Can Biodegradable Products Be Bad For The Environment?


"If a biodegradable material is placed in a landfill, then during biodegradation it’s going to be converted into methane and carbon dioxide. Some landfills recover the methane for energy. Some recover it, but just burn it. Some do not recover it. According to the EPA, about 35 percent of waste is in landfills that use the methane for energy. About 34 percent is in landfills that burn it, but don’t recover energy. And about 31 percent is in landfills that just release it to the environment.


Even when we say methane is a good energy source, which is true, it’s only good if you recover it and use it. That’s not always happening. That’s one major point. The landfills that don’t collect the methane and just have it released in the atmosphere are the subset causing the environmental problem."
