Biodegradable materials are less expensive than plastics because they go directly to the state plastics aim to achieve, which not only saves on processing, experimental, and labor costs but also saves time. Biodegradable materials help save the cost of products in two significant aspects:
(1) Save the cost of the product itself. Thinking about the cost of removing BPA from plastics, heavy metals from plastics, and harmful chemicals from plastics, biodegradable materials are really cheap. What is the cost if you make petrochemical plastics degrade like paper and wood in a short period of time? The cost is high, and R&D will take a long time, but biodegradable materials could be produced directly, such as paper and wood, at very low cost. Also, microplastics are always a headache that has never been solved for all kinds of plastics since their invention. Many sea mammals and fish died from microplastics, and many microplastics even enter the human body. How can you solve it? What will be the cost? Plastics factories should ask their R&D department to estimate the cost; it should be an astronomical figure. But the cost of biodegradable materials is only the negligible price per ton.
(2) Save all kinds of hidden costs, especially related to social. Plastics have a substantial environmental impact, forcing governments to incur considerable costs to address environmental pollution and to spend a lot of funds to address public health problems caused by plastic pollution. Where does this money come from? It comes from factories, other companies, taxpayers, and individuals. If this money could be saved, it could be used to support education and help people in need, thereby increasing a country's consumption capacity, which would benefit manufacturers and lead to better sales.
