Problems solved by technology

Thus, while recycling does significantly reduce the environmental cost of producing virgin plastic materials, it has its own environmental disadvantages
These issues make conventional plastics no longer a sustainable solution in applications such as packaging and short-term use products, where large amounts of plastic material are generated and discarded

Embodiment Construction

[0019] The present disclosure provides, in some embodiments, macrophyte-based compositions that exhibit thermoplastic properties. The composition may include macrophyte biomass material mixed with a thermoplastic polymer and other additives to define a bioplastic composition. Natural compounds in macrophyte biomass materials such as natural proteins and carbohydrate polymers in macrophyte biomass materials can be combined with thermoplastic polymers and other additives to produce plastic materials that appear to be acceptable for most plastic material applications. Balanced composite composition of polymeric and reinforcing properties.

[0020] Unlike plastic compositions made from non-renewable raw materials and renewable raw materials derived from edible food sources, macrophyte biomass in macrophyte-based compositions can be readily obtained from environmentally sustainable sources regeneration. For example, macrophyte biomass material can be harvested from wastewater col...

Abstract

A bioplastic composition may contain certain biodegradable and renewable components. In some examples, the bioplastic composition includes at least one kind of aquatic macrophyte biomass, which may contain a native composition of protein and carbohydrates, in a blend with one or more types of biodegradable or durable thermoplastic polymers. The aquatic macrophyte composition may provide a balance of both polymeric and reinforcing properties to the blended bioplastic not typically exhibited by terrestrial feedstock such as soy meal or corn starch. Such a bioplastic composition may be formed into molded articles using extrusion, injection molding, compression molding, or the like.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 526,814, filed August 24, 2011, the entire contents of which are hereby incorporated by reference. technical field [0002] The present disclosure relates to polymeric materials, and more particularly, to polymeric materials comprising macrophyte biomass. Background technique [0003] In our modern consumer society, plastic has dominated the market as the material of choice for most applications including packaging. This phenomenon is not entirely unwarranted, as conventional plastics are strong while maintaining low weight, offer resistance to degradation by water, chemicals, sunlight, and bacteria, and provide electrical and thermal insulation . All of these properties make conventional plastics versatile for many applications; however they also pose environmental concerns. HIPS (High Impact Polystyrene), a commonly used plastic polymer, uses 99.8 GJ of energy mainly from natural gas as an en...
