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

in 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.
