Biodegradable plastics are commonly used for disposable items, such as packaging, cutlery, and food service containers. [13] In principle, biodegradable plastics could replace many applications for conventional plastics. However, this entails a number of challenges. Many biodegradable plastics are designed to degrade in industrial composting ...
Using minimal packaging has also been a common goal to help reduce costs. Recent years have accelerated these efforts based on social movements, consumer pressure, and regulation. All phases of packaging, distribution, and logistics are included. [11] Sustainable packaging is not focused on just recycling.
Other properties of biodegradable polymers that are common among those used for medicinal usages include being: non-toxic; capable of maintaining good mechanical integrity until degraded; capable of controlled rates of degradation [8] A goal is not to elicit the immune response, and the products of degradation also need not to be toxic.
Starch-based films (mostly used for packaging purposes) are made mainly from starch blended with thermoplastic polyesters to form biodegradable and compostable products. These films are seen specifically in consumer goods packaging of magazine wrappings and bubble films. In food packaging, these films are seen as bakery or fruit and vegetable bags.
Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14] Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts.

House Speaker Mike Johnson, R-La., spent hours on Thursday behind closed doors meeting with other lawmakers and hammering out the pared-down bill, absent several of the provisions that had upset ...
Biodegradable films need to be kept away from the usual recycling stream to prevent contaminating the polymers to be recycled. If disposed of in a sanitary landfill, most traditional plastics do not readily decompose. The conditions of a sealed landfill additionally deter degradation of biodegradable polymers.
