The document discusses biodegradable plastics as an alternative to traditional plastics. It states that biodegradable plastics break down into water, carbon dioxide, and biomass when exposed to oxygen and microorganisms, just like dead organic matter in nature. However, biodegradable plastics still require proper disposal in industrial composting facilities to fully degrade since regular environments may not provide suitable conditions. The document also notes that biodegradable plastics are primarily produced through microbial fermentation of plant biomass.
