Negative Impacts of Bioplastics
A. Risk of Contamination: Biodegradable plastics and Non Biodegradable plastics must be thrown away in separate garbage bins, and not all people know how to distinguish between the two, so there is a risk of contamination. If both the plastics are mixed, then they are of no use as then we might not be able to recycle biodegradable plastics.
B. Need for Composters: To convert bioplastics into composters industrial composters might be needed and if this is not the primary preference of the government then some countries might not be having the required equipment and as a result, bioplastics will not be discarded properly.
C. Engineering Issues: Since bioplastics are Bio-based and that means their source of origin is organic, i.e. soybeans and corns. But these organic plants contain chemicals that can be harmful to the crops because of the pesticides that are sprayed on them and that can pollute or contaminate the final product.
Bioplastics: Application And Impact On Environment
Bioplastics are the kind of plastics that requires the use of renewable or organic resources such as vegetable oils and starches for their manufacturing. By 2025, petroleum used in the manufacturing of Bioplastics is expected to decrease by 15-20%.
Bioplastics can be made from renewable resources (Biobased), or they can break down naturally (Biodegradable), or maybe both. Carbon Dioxide produced by almost all the bioplastics is less than the usual plastics. They are not always wholly green. While biodegrading, some bioplastics can also produce carbon dioxide or monoxide. Under the right circumstances, some biodegradable plastics can take 180 days to break down.
