Black plastic black plastic does not raise soil temperature as high as clear plastic and will not kill pathogens or fungi.
The black polyethylene film is 4 mil thick and can cover up to 200 sq.
Whether the latter results in true biodegradation is a matter of hot debate.
But it can be more effective at killing weeds.
Adding a catalyst to conventional plastics to hasten the degradation after exposure is another approach.
We are neutral about which approach is the most sustainable packaging.
