Renewable & Recyclable Materials

Renewable materials are also knon as sustainable materials, these materials do not use up non-renewable resources. They can also be produced in high enough volume to be economically useful. Biopolymers are one such renewable material. A biopolymer is a naturally occurring polymer, such as carbohydrates and proteins. Some examples of biopolymers are cellulose, starch, collagen, soy protein and casein. These raw materials are abundant and biodegradable, and are used to make diverse products such as adhesives and cardboard. Recyclable materials include many kinds of glass, paper, and cardboard, metal, plastic, tires, textiles, and electronics. The composting or other reuse of biodegradable waste—such as food or garden waste—is also considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials destined for manufacturing. PHAs are biodegradable plastics, they are used as an energy and carbon storage compound within certain bacterial cells. The industries are looking forward to replace the Plastics, which are non-Bio degradable.Some of the biodegradable biopolymers are compostable: they can be put into an industrial composting process. Biodegradable polymers have an innumerable use in the biomedical field, particularly in the fields of tissue engineering and drug delivery.
