What environmentally friendly materials are generally more environmentally friendly and sustainable? 1. Bio-based materials Bio-based materials are extracted from renewable natural resources and are therefore more environmentally friendly and sustainable than traditional petrochemical materials. For example, bio-based plastics are made from natural substances such as vegetable oils, starches, and wood fibers, and their manufacturing process produces fewer carbon dioxide emissions than petrochemical plastics. In addition, bio-based materials can degrade and will not leave toxic microplastics in the natural environment, resulting in less impact on the environment. Compared with traditional materials, bio-based materials have better reproducibility, degradability and biodegradability and are considered
