Architects from the Japanese design firm Bakoko have developed a circular structure, called the Comploo, that could be the perfect sustainable compliment to Japanese Tea Gardens during chilly winters--heated by a unique composting system built in the walls. Designers say that the heat captured from the organic waste breaking-down could heat the space to temperatures nearly 120º F, all while producing compost for the garden.
The key to the design is in the special decomposing compartments that line the walls. When food or garden waste is put inside, the heat generated by the microbial processes is circulated throughout the room. A glass ceiling acts like a greenhouse to capture heat from the sun as well.
And, after the heat has been captured from the material, what's left is useful as well. According to the designers:
A steady supply of rich organic compost is extracted from a door at the bottom of each bin. It fertilizes new vegetation that will eventually become fuel for the next cold season. The concept is suited to large urban parks, community gardens, or even serving as an outdoor café - anywhere that generates a continuous supply of organic waste for fuel.
There are a number of kinks that need to be worked out before the Comploo can be considered a viable alternative to outdoor garden structures--namely the stench produced by the decomposing organic waste. Nevertheless, according to a report in Galileu, designers will be unveiling a prototype in the near future.
