According to the research, “when natural gas was used, the impact on production was comparable, and when clean, renewable energy (geothermal) was used, the research shows that bio-bags are 80% more environmentally friendly.” The following diagram describes the life cycle of polypropylene plastic bag, made from crude oil, and bioplastic from renewable resources such as crops. Although bioplastics are preferred over petroleum-based polymers, the amount of energy used in the life cycle process causes some concerns. Looking at the life cycle provides some insight into where the real problem lies
