Most plastics are non-biodegradable mainly because plastic is widely used because of its low cost, versatility and durability. This durability is partially based on plastic being an uncommon target for bacteria, which makes it non-biodegradable. Biodegradable plastic is made from fossil fuels and is subject to accelerated environmental degradation due to its chemical formula. The main problem with biodegradable plastics is that they don’t usually work. The problem is that 25 weeks for composting a product is too long. Create. Continue Reading. Mixing biodegradable plastics with regular waste can hold some problems – the waste management infrastructure in most places is not suitable for biodegradable plastics. The major problem with traditional plastic is that it takes an extremely long time around more than hundreds of years to break down once discarded, whereas biodegradable plastics use alternate materials or specialized enzymes or chemicals to break down the content between three and six months, once exposed to the elements. So making the biodegradable plastics common material in this area can save the world from pollution with conventional plastics. plastic pollution around the world [5]. Compostable plastics are biodegradable in composting conditions, while other plastics degrade in the soil (landfills or anaerobic digestors). It is important to note that compostability is a characteristic of a product, packaging or associated component that allows it to biodegrade under specific conditions (e.g. Even biodegradable plastics can take years to break down if they end up in the sea. The Problems with Petroleum-Based Plastics The push to develop bioplastics emerges from alarming realities starting with the staggering quantity of plastics being manufactured. Biodegradable alternatives to conventional plastics. In a marine environment, plastics may migrate long distances, accumulating on shores and in mid-ocean vortices, causing harm to marine life and to the marine environment. But the idea that bottles and packaging made of plant-based material can simply be discarded and then break down and disappear is false – recycling and … They are usually mixed with additives that give the products properties such as durability, flexibility or color.
