produce thermal energy and biofuels. Multi-stage bioconversion takes place in several stages. To perform a multi-stage bioconversion, you need to use mixed cultures of microorganisms or add different strains of microorganisms at different stages of the process.

compost piles, special boxes and barrels.
It is advisable to add:
sugars, nitrogenous compounds and composting bacterial accelerators.

Green raw materials are rich of nitrogen. And brown raw materials are rich of carbon. Optimal proportion of carbon to nitrogen is 25-30 to 1.

2016 in New York 23 thousand tons of waste were collected, such as: orange peels and apple seeds etc. Now their main problem is in densely populated areas, it is difficult to find a place for additional containers.
