At Hackerspace Phnom Penh we are always trying to new ideas. Salla Mäkinen had been talking about composting kitchen waste. One afternoon I decided to try to make DIY compost bin with Salla's help. The design is simple and easy to make in less than an hour.
We head down to hardware shops along the Russian Market area to buy used paint buckets. The first bucket with a lid holds the composting material and the second one collects the drainage seeping from the compost. Salla and I drilled lot of small holes in the first bucket. Then put in four large bolts to hold the bucket up, this seems better design than putting a brick at the bottom. That's it. Now the compost bins are ready for my kitchen waste.
We need to improve this design to make it easy to churn the compost for aeration. Let's use know if you have any design suggestions. And do come over to Hackerspace Phnom Penh if you are interested to learn to make your own DIY compost bins for your kitchen waste.
