Gumboot pots and Paper chains

Want to make your house pretty without consuming more, find creative activities for children that don't involve buying more, and/or re-use some of the stuff around your house that is no longer wanted? Here are two ideas that do all three.


Gumboots! There are so many cool kids' ones around but, no matter how funky, they still wear out or (if you're lucky) kids grow out of them. What to do with all that rubber-plastic prettiness?


A few spring flower punnets and an hour of working together and we have had these decorating our entrance for the last two months.


Although we did buy potting mix, more than half the soil was made up of our own compost. (We have three compost tumblers and our guinea pigs contribute substantially to this enterprise!)


Five of these six gumboots drained sufficiently without any help; the sixth needed a couple of holes added. Summer has nearly killed them off now and direct sun has faded the gumboots significantly, but we may get second season out of them and meanwhile, it has been a lot more fun than just binning them.


Your children might not rip through gumboots at quite the rate we do, but if you have anyone small in your house you are certain to have a pile of kids' artwork mounting up. And old posters. Calendars. Wrapping paper. (Most people I suppose have junk mail or magazines, but we don't receive them here)


Eva got inspired to make paper chains for Christmas and it was a great use for the build-up of paper.


Because they were using their own old artworks and posters they were willing to 'repurpose' things that I had not been allowed to throw away (sneaky, huh?!).




Note the hole-punching above. If you have someone who loves hole-punching, its not a bad way to add interest to strips from old calendars while keeping those hole-punching-hands from less productive outcomes.


They both loved making the chains and I am happy to have our living room decorated by their creativity and enthusiasm.


Initial Time: Both of these activities took about an hour. That was part of the point. We have no TV and its school holidays again. Creative, engaging, sustainable activities are what we need plenty of here. (I last wrote specifically about this when Eva was quite small but if you search the labels below for 'free kids activities' there are also other places it has come up as she has got bigger)

Initial Cost: Gumboot pots: about $30 for seedlings and a bag of potting mix; Paper chains: a couple of dollars for a big box of staples.

Ongoing time or cost commitment: We will eventually have to take both these things down and they will ultimately end up in the recycling (chains) or the general rubbish (boots).

Impact: It is impossible to really calculate an impact for these activities and, to be honest, it would probably be quite small anyway. But both are little bits of a bigger picture: finding ways to reuse everything until it really is beyond use, rather than chucking it out after its first purpose; avoiding buying stuff to meet a need (and considering whether it is in fact a need at all); helping children to be creative; celebrating colour and beauty and natural things; finding the quality in our own creative effort rather than needing a professional or 'perfect' outcome (often with associated waste) in order to be happy; sharing activities together and working collaboratively on a combined project.

A visit to the super composter

This 'sustainability action' was one to educate ourselves.


We were given the opportunity to join a group from Uniting Church in the City for a tour of the Neerabup 'Resource Recovery Centre', which is operated by Mindarie Regional Council. Basically, it is a huge composting plant, taking the waste from general (green lid) rubbish bins and processing it to extract organic matter and make it into usable compost.


If this doesn't sound like fun to you, ask any pre-school child how they would like to see where the bin trucks go with our rubbish.
 


Our small boy was beside himself with excitement; our big girl was jealous because she had to go to school instead. The word 'grapple' entered our basic vocabulary and play.


The Mindarie Regional Council serves the local government areas of Wanneroo, Stirling, Perth, Joondalup, Cambridge, Vincent and Victoria Park. However, the bulk of the waste taken to the composting facility comes from Joondalup, Vincent, Wanneroo and Victoria Park. The facility processes 100,000 tonnes of waste a year; the seven councils that make up the MRC together put about 160,000 tonnes of waste into our general rubbish bins, so quite a lot still goes straight to landfill. About 30-40% of the tonnage received at the facility comes out as compost; the non-organic remainder also ends up in landfill. So, there is still lots of behaviour-change work to be done, but 30-40,000 tonnes of compost each year diverted from landfill is a great thing.

Here's the page that explains how the 'Resource Recovery Facility' actually works to extract compost from general rubbish. Or here for the commercial version.


Initial Time: Half a day

Initial Cost: $10 for the bus.

Tours are offered free, but you need to book. Here's the website with details for various tour options (I have heard there is more rubbish truck action at Tamala Park landfill, if entertaining children is part of your brief). Our tour was run by the inimitable Peg Davies, who I think does a great many of them. She really knows her stuff.

Ongoing time or cost commitment: Continued sorting of rubbish into regular or recycling bins, with greater attention to keeping glass and ceramics out of the regular bin.

Impact: I learnt a lot. I also found it really encouraging to see the efforts being made to keep organic matter out of landfill. It helps me to keep doing our little things when I see organisational attempts at bigger things like this.

removed section of composter
The biggest learning was the call to keep glass and ceramics out of general rubbish. Put them in the recycling, broken or not. Glass in the compost is a major problem, because it is nearly impossible to completely sieve it out. I had not taken the notices about keeping glass out of general waste very seriously, because I couldn't conceptualise how general waste could be turned into compost anyway. Now that I have seen it in action I get it: If you live in Wanneroo, Stirling, Perth, Joondalup, Cambridge, Vincent and Victoria Park DON'T PUT GLASS IN YOUR GREEN-LID BIN. Thanks.

If you are in the East Metro Regional Council - Bassendean, Bayswater, Belmont, Kalamunda, Mundaring and Swan - planning for a similar facility at Redhill is underway, aiming to be operational by 2019. So when the 'no glass' notice comes around, take it seriously! 

If you are in another area - how about writing to you local council to let them know that you think these places are a good idea?

Special birthdays

When Tyson turned forty in June we wanted to celebrate him well, without massively increasing our footprint. 

The main agenda was to gather people together and enjoy each other, with good food. But here are a few things that also had an eye to our sustainability commitments:


We asked for gifts of sustainability actions in lieu of presents, and were touched by how many friends offered Tyson some idea of what they are doing to live within our earth's means. Some made new commitments; others reiterated choices already made. I was particularly moved by one (slightly) older friend who gifted to Tyson her decision to make more use of public transport, along with an invitation to ask her how it was going and an admission that the idea of using public transport scared her a bit. The traditional photo board included space for people to add notes about their sustainable choices.


Cooking one big roast dinner for sixty people used less energy than all those households cooking their own roast dinners at home (and was more fun!). We used about 15kWh of energy for cooking; a household roast dinner takes around 2kWh. The meat was free-range pork.


We borrowed cutlery and crockery from Tyson's parents to reduce our use of disposable items. We still have a pile of disposable plates, cups and cutlery in the cupboard from before we really got moving on this sustainability journey, some of which have been reused and returned to the cupboard several times, and these bumped up the numbers, along with some compostable plates. (I have my doubts about how they compost, though - I tore them into quarters and soaked them in water for a week and they were showing no signs of breaking down or being suitable for our compost any time soon!) Despite me encouraging guests to leave the dishes for us to run through the dishwasher in big loads the next day, a happy team got going in the kitchen and cleaned them all for us. They really did seem to be having a great time in there. Perhaps for some this was their sustainability 'gift', but most I think just enjoyed talking and laughing while working together.


We minimised our use of gladwrap and alfoil. So often at parties or events these are used to cover food for quite short periods of time. Instead, we used baking trays to cover salads.


We labelled our bins and encouraged people to separate out compost, recycling and genuine rubbish.
 

Eva made her own decorations. We also re-used the cloth bunting made for us by a friend last year, and ran one string of LED fairy lights.


Cards were home-made. The two gifts we did purchase were wrapped in cloth, one from each of the children. (We are not scrooges; its important our kids experience both giving and receiving. We encouraged them to be involved in choosing gifts that suited Tyson, to help them learn to think of someone other than themselves) The cordless drill set in particular will be put to use to facilitate many future projects along our sustainability journey.


Two weeks later my dad turned eighty, on the opposite side of the country. We celebrated by all my siblings (five of us) gathering, along with spouses and children, to share a holiday in the Grampians with my parents. The emphasis, again, was good time together. Bushwalking. Eating. Talking. Cuppas. A visit to the farm where Dad grew up. Grandkids' shenanigans. Reading books. Spotting wildlife. My gift was to arrange for my sisters and I to sing a couple of songs for Dad.


However, as we don't live near each other (not even all in the same country) a very great amount of fuel was used to bring us together. Would we have had less environmental impact if we had all sent my dad expensive presents instead? Maybe. But we would not have celebrated him well, and we would not have modeled for our children that people are always, always more important than stuff. 


Happy birthday to two of the finest men in my life.  

Some of the sustainability actions Tyson was gifted:



And finally from our small man, a gift not of sustainable actions but of hope:

Reusable barrier bags

Do you know what a 'barrier bag' is?


You might not be familiar with the terminology, but chances are you are very familiar with the item: the single-use lightweight plastic bags that are available on rolls when you buy fruit and veg, or whole foods, so your apples and potatoes don't get in a muddle in the trolley.

I have for some years now tried not to use these bags, keeping items loose wherever practical. However, while it might be OK to have a few onions rolling around, soft things like stone fruit or small things like almonds really need something to contain them.

For my birthday last month, my caring and ever-thoughtful mother-in-law made me a set of cloth barrier bags. They are a simple rectangle, in various sizes, with a ribbon draw-string. The fabric is silk voile (lace curtaining) which means the checkout staff can see what is in each bag. 


So our May commitment is to remember to use them! We also intend to use paper bags to cover any excess need, to be added to compost when they become unusable. Fruit and veg shops generally provide paper bags for mushrooms, and they can easily be adapted for other uses. The wonderful Kakulus Sister in Fremantle provides them for their dry goods in general, which gave me the idea.

We also use these bags for storing some fruit and veg in the fridge, which so far seems to be working fine. There will be a few things that are very powdery for which we will have to use paper, as I think flour or the like would not quite be contained.


Initial Time: For me, zero. I'm not sure how long it took Tyson's mum to make them. She's very good at sewing, but even if you were less skilled it is a simple project. 

Initial Cost: For me, zero. To make yourself: simple ribbons generally cost $3-$5 a metre, although they also seem to turn up on all sorts of things, so if you are not picky about making them match you can probably find some around the house. Or use string. Wool. Old shoelaces. Whatever you can salvage. Fabric prices vary widely, but at say $10/metre your bags would cost about $1 each.

Ongoing time or cost commitment: Remembering to take them and use them. They are stored with our cloth shopping bags, so in theory this is easy, but we are taking a while to get into the groove. Occasionally they need to be washed after use (mostly not). When empty, they need to be returned to their storage place rather than binned. 

Impact: 

Australians use approximately four billion single-use shopping bags a year. The average useful life of those bags is twelve minutes. Around 86% end up in landfill, where even if they are supposedly compostable they do not really break down, due to the highly compacted nature of landfill. Although most people report using plastic bags two or three times before disposing of them, ultimately they still end up in the bin. The remainder end up as litter, choking up our environment and particularly damaging waterways. Marine life is severely impacted by plastic waste. Once the bags begin to deteriorate, they contribute to 'micro plastics' - microscopic plastic fibres that are being found in sea creatures in increasing quantities. Including sea creatures we eat. 

At the other end of the process, producing plastic bags is a polluting process using non-renewable resources. China banned plastic bags in 2008 and it is reported to have saved 1.6 million tonnes of oil the following year.

I estimate that our family uses around 260 barrier bags in a year. There is some environmental cost in producing the cloth bags. Choice has calculated that a green shopping bag needs to be used 23 times before its production footprint is less than the equivalent in plastic. Given that our bags are of polyester fabric, I imagine we need to use them at least 23 times and probably a few more, so we pull ahead after about one year of use. 

While researching to write this post I discovered that a government campaign in 2003-2007 to phase out plastic shopping bags, which I had thought was ongoing, ceased in 2008. Plastic bag use leapt 17% the same year. Some States have gone on alone to regulate against single-use plastic, but not Western Australia. After this election I think I will write to whoever forms government to remind them that quite a lot of people would like those bags banned. If China, Rwanda and Bangladesh can do it, surely we can manage here?

Sustainable catering

Last month Tyson and I organised the catering for a one-day retreat.


Back in May I wrote about taking cutlery and crockery from home to attend a conference, to avoid using the disposables provided. In fairness to the organisers of that conference, I should have noted that they were all volunteers (some of whom read this blog) and that they had made the effort to provide compostable disposables, which cost quite a bit more.

So when it was our turn to cater, we thought we had better listen to my own critique and aim for sustainable catering. Primarily, this meant not using disposable cups, plates or cutlery. We were ready to wash dishes ourselves, but set the kitchen up so others could easily wash or dry. We found that the friendly retreat participants were mostly happy to pop into the kitchen and do it themselves.


The central kitchen sink had its own hot water system. We opted not to turn it on and have it run all day, but rather to use water from the urn (a wall unit that was permanently on anyway) to top up the sinks. We provided Fair-Trade tea and coffee. We also offered a compost bin, to reduce the amount of food waste going into landfill and use it instead for our garden.


Initial Time: The set-up time was no greater. A little extra time for thinking around how to do it, perhaps.
 
Initial Cost: Zero. The cost of a few teaspoons of washing up liquid and laundry powder is negligible. There was a cost saving in not purchasing single-use items.
 
Ongoing time or cost commitment: 
Actually washing dishes was a small part of our day, shared between the three of us running the kitchen and many of the retreat participants. The chatter around the kitchen sink was a lovely community-building space.



There were small follow-up tasks, like carting the compost home to put into our compost tumbler and putting the tea-towels through the wash, but these were very minor within the overall tasks of organising the food.
 
Impact: As discussed in May, Australians use about 2.7 million disposable cups a day, and probably nearly as many plates and pieces of cutlery. In China it is disposable chopsticks that are a problem - causing deforestation to keep up with demand for tens of millions of chopsticks each year.

Catering for thirty people, we saved from both production and disposal around thirty dinner plates, thirty dessert plates, thirty bowls, sixty coffee cups, fifteen water cups, sixty spoons, thirty forks, and ten or so knives. That's a small dent in the millions used each day, but a dent none the less. 

And as often happens when we take an action in a public space like this, even quietly, it generated quite a few conversations and hopefully set people thinking at least a little about their consumption and disposal.

12 December 2010

Now its December...

So as you can see, I have not been the least bit successful at keeping up with this blog. I have to confess that as we headed into the second year of our sustainability commitment we also began slipping away from doing something every month. Having said that, though, we are still averaging one thing a month and not naming it as part of the original commitment.

Things we have done this year since May:

Garden make-over. This involved help from about ten friends, bless them, especially the guys who forked a whole trailer load of woodchips in and then out of the trailer, and around the garden. The garden make-over was to reduce the water needed for the garden (and also to reduce the number of spidery corners as our little girl began to get mobile) and also, we hoped, to improve our vegetable returns. We installed a raised garden bed and Tyson reworked the gravity-feed irrigation system to service it. Most of the front courtyard was woodchipped to get rid of grass areas, and the remaining woodchips were used to mulch every pot and garden bed around the house. Initial time: one full working day with an average of five workers at a time, plus another day with two of us finishing things off. Initial cost: about $300 for sheets of corrugated iron and a few sturdy posts (all from the salvage yard), two trailers of good quality soil, and a donation for the woodchips that we collected from the front lawn of a church that needed to get rid of a large fallen tree. Ongoing cost: various bits and pieces, but no more or less that for any other garden - well, perhaps less, as vegetable seeds cost less than, say, pots of orchids, and the most successful vegies have been the ones grown from seed either harvested at the end of season or accidentally sown through the compost. Ongoing time: Less than for most gardens, as the woodchips stop most weeds and there is no longer grass to mow. Impact: Sorry, I just can't calculate that one. But I know that the new garden makes me happy, and I spent much of winter just enjoying looking at it out our windows.


Rugs and Carpets. Our living space is tiled, which in winter means it can get quite cold, but in summer it is lovely. This year we acquired two more floor-covering pieces for winter, making five rugs on the floor in winter. One was a second-hand piece from a nearby carpet store, which Tyson trimmed and turned around to fit under our dining table and chairs. The other was from his parents as they were replacing a large rug at their house. For summer we have lifted three of the pieces, leaving soft coverings only at the areas where Eva's toys are kept, so that she has some softer play space. Initial cost: zero (except maybe the $5 for a roll of duct tape for reshaping carpet pieces into the floor piece we needed. We didn't use the whole roll, of course) Initial time: about 15 minutes going through carpet off-cuts to find a decent piece; about 30 minutes for Tyson to work the carpet into a good shape. The rug given to us was no time at all! Ongoing time and cost commitment: about 5 minutes at the change of seasons to pull up and store or lay down again the rugs. Storing a couple of large rolled carpets through summer is also a bit of a space-taker. Impact: Its hard to prove whether we turned the heater on less in winter once the carpets were down, but I suspect we did, as my feet didn't feel cold when working on the laptop at the dining table. As for summer... Eva sometimes lies down on the nice cool tiles when it is hot but so far I have not got hot enough to shake off my social conditioning that says adults probably shouldn't be found lying on their kitchen floor.

Bamboo blinds for the back window.  We were given a couple of bamboo blinds so Tyson rigged one up on the back toilet window. This room gets the afternoon sun and absolutely bakes in summer. The blind fits perfectly and makes an amazing difference! Initial cost: zero, as the blind was a throw-away. Initial time: about 15 minutes to attach the blind - hooked into the small screen/vent at the top of the window with hooks Tyson made for the job. Ongoing time and cost: zero. Perhaps in winter we will decide to take 5 minutes and roll the blind up again at the start of the season. Impact: We never heated or cooled the toilet, but it was a very hot buffer between outside and inside temperatures. As it is now substantially cooler, the inside temperature is not pressured nearly as much from this side. Its also much MUCH nicer in there on a hot day - which, although it is not the toilet we mostly use ourselves, is a huge improvement as it is the room where nappies get dealt with.



Making Eva's Christmas present out of items salvaged from hard rubbish. The items: two dolls' houses. Tyson is in the process of renovating them, pulling bits off one to make the other perfect. So far everything he has done has used recycled materials from around our home, except for the rewiring of the lights. Initial cost: I think Tyson spent about $30 on wiring and little LED lights. He tells me he is working on a plan to put a solar panel on the roof and run the house lights that way. I'm not sure how serious he is. Initial time: Lets just say this is a labour of love for Tyson and he has spent many happy hours in the shed pottering about creating the perfect recycled dolls house. Ongoing time/ cost: hopefully zero, but probably a few repairs along the way. Impact: most of two dolls houses saved from landfill; numerous bits and pieces of household 'waste' saved from landfill (did you know a plastic honey sachet makes a great sink?); all of us saved from buying more stuff for Christmas for this one time, a tiny ripple against the great tsunami of Christmas consumption.

Shed vent. The shed is a tiny tiny place, from which Tyson has to unpack several items in order to have space for himself to get inside if he wants to use it as a work space. It is also extremely hot and humid, as it was built with no windows, vents, or openings other than the door. Tyson bought a vent and installed it so that hot air could escape into the roof space above the ceiling and thus through the tiles. I don't go into the shed except to reach in and get a broom or snail bait, but even those brief forays were unpleasant pre-vent. Tyson says the vent has totally transformed the place into a viable workspace. (For the record, no we didn't ask permission from the landlord. I'm sure he would have said yes - eventually. Everything takes forever on that front. We figure we've made an improvement, at our cost, so if he even notices the vent he surely can't complain). Initial cost: bout $15 for the vent. Initial time: I'm starting to forget details, but I think cutting a piece of ceiling out and fitting the vent into the space took about half an hour. Tyson is pretty handy. It would probably have taken me at least twice that long. Ongoing time/ cost: zero. Impact: we didn't heat or cool the shed, partly because there is no power point in there (you gotta love investment builders ... don't put anything in past the bare minimum specs if you won't be living there yourself!) but Tyson doesn't come inside wilting and need cooling down like he used to. Also I think it counts as a sustainable action to improve quality of living without increasing energy usage or global impact.

Better compost system. We decided to put some of the money left to us after Tyson's beloved grandmother died towards buying a decent (read: completely sealable) compost system. It works. It also seems to breed tomatoes, capsicums and pumpkins effortlessly. Initial cost: $200. Initial time: about an hour to assemble the tumbler, transfer the existing compost pile into it, and get the new tumbler settled into its garden home. Ongoing cost/ time: five minutes a day to put the scraps from the kitchen into the tumbler and give it a spin. Impact: great soil! and self-sown vegies. I don't think we will need to buy potting mix for a while. Also of course we are saving all that organic matter going into landfill.

Tarpaulin shading the northwest wall. In summer this wall soaks up heat in the afternoon, and transfers it pretty quickly through into the living area. Our clothesline is there, and last summer I had tried making sure there was washing on the line on hot days to provide some shading, but this was not really enough. This week Tyson has rigged up a tarpaulin to cover about half of the courtyard on that side of the house, shading much of the wall - and also a decent chunk of the shed. It is hooked into the gutters with metal hooks, and tensioned with shock cord (left over from earlier exercises in shading windows). So far we think it is helping reduce house temperatures. We haven't had a real heat wave to trial it on yet. Much of the clothesline is shaded now, but only the nappies really need direct sun and they can either go on the sunny bit or go on a free-standing drying rack out in the hot bit of the courtyard. Initial cost: zero (the tarpaulin was given to us by a neighbour who was getting rid of it; the shock cord was left-overs) Initial time: about half an hour. Ongoing time/ cost: this one will need to be taken down in heavy weather, as it blows around a bit. Its also quite noisy, so Tyson is thinking of ways to soften the scratchy noise of the hooks in the gutters. Even if it doesn't come down in heavy weather, it will need to come down at the end of summer.Impact: Reduced need for airconditioning in summer. Possibly also longer life for clothes that don't appreciate drying in direct Perth summer sun!



 
Front blinds. It took us ages but we finally found a spot suitable for the second of our donated bamboo blinds - a larger one. I was hesitant to allow Tyson to put the blind on the front living area window, as I love sitting in the lounge looking out at our front garden - especially since it got remade at the start of winter. However, we tested it out and to my amazement you can see right through bamboo blinds, much like a fly screen but not so grey! I'm sure everyone else in the world already knew this, but it was news to me. The blind is hooked into the gutter - no permanent fixtures. It can be retracted with a draw-cord, but so far we haven't bothered. Initial cost: zero (blinds were a cast-off gift). Initial time: about 15 minutes to put the blind up. Ongoing time/ cost: need for removal at start and end of season, and probably during heavy weather as they are loosely attached to the guttering. Its the lee side of the building, though, so not too punished by weather. Impact: I can have the inside venetian blinds open in summer without heating up the house dramatically - which is extremely good for my mental state when I am home all day with Eva on a hot day. I know shutting the blinds is good sustainability sense, but I get tetchy living in a cave. Somehow the sun still sneaks in the side of the blind until about 9am (later when its not the middle of summer), so the venetians are still shut then. Overall it seems this is making the room much cooler, hence less airconditioning. And the not-cave effect makes me happier about living in a shaded house.

Tyson's work. In October Tyson passed his 100th home sustainability assessment. That's something like 200 hours spent one-on-one educating people in their own homes about ways to reduce their impact. If everyone he visited reduced their energy bills by one unit per day (not an unreasonably estimate as an average) he would have taken about 21.5 tonnes of carbon out of the air (as of today). We heard yesterday of a family of four who he visited about six months ago who have since installed solar panels and made lifestyle changes so that their last energy bill was $1.05!
