Packaging Strategies Feb 7, 2019
Various life cycle analyses on compostable packaging demonstrate that compostable materials have lower environmental impacts than traditional plastic packaging. A life cycle analysis is a tool that looks at the impact of sourcing, manufacturing, and transporting a product.
Compostable products use less water, require less energy, and generate fewer greenhouse gas emissions during the manufacturing process. This is true for both products made from plant fiber and compostable bioplastics.
Plastic packaging, on the other hand, generates more greenhouse gas emissions because it is dependent on fossil fuel extraction and processing. There are also uncalculated negative impacts from disposal, because plastic packaging is usually too dirty to be recycled (see below), and instead ends up as litter or in the landfill.
