There are already polymers that are 100 % biodegradable and are not made from oil. A "100% biodegradable polymer" is one that is totally turned into carbon dioxide, humus, and water by soil microorganisms. Genecis produces biodegradable polymers called PHA or PHBV (poly hydroxybutyrate-co-hydroxy valerate).

Even though the phrase "biodegradable polymers" is very well-known, the debate about whether polymers should be called biodegradable remains inside the market.
Genecis' biodegradable polymers are synthesized by microorganisms and have received a lot of interest. In a large-scale decomposition experiment, the PHBV film decomposed, and in the research lab control compositing test, the rate of microbial degradation was 81 percent.
Genecis is a company that converts food waste into biodegradable polymers. Polymers generated from natural sources, such as food waste, could be used to make bioplastic. Sewage trash, cassava skin, fruit peels, papaya peel, durian kernel, jackfruit kernel, avocado kernel, and poultry feather all come out from the processed food industry or domestic usage.
Genecis has developed the first budget PHA polymer for commercial application by using food waste for disposal.
Food waste is defined as food that is not consumed. Food waste can happen at any point in the food supply chain, including during manufacturing, processing, transmission, wholesaling, and consumption.
Approximately one-third of the planet's food is wasted in landfills. Fruit peels, coffee beans, rotten fruit, expired bread, and other food waste that needs to be disposed of might be turned into biodegradable plastic packaging that could be used instead of single-use plastic materials.
Bioplastics are made from bacteria found in sugars, carbohydrates, and proteins found in food: PHAs or polyhydroxyalkanoates are produced by microorganisms that feed on bacteria and are isolated and used to make polymers.
The two-step method depends on two groups of unique bacteria that work together to decompose food waste and produce short-chain carbon covalent bonds in the form of vfas or volatile fatty acid, which serve as a preparatory feedstock for the second category, which consumes those carbons and transforms them into PHA bioplastics.
PHA is a biodegradable material used to make injection-molded packing, plastic containers, glasses, straws, grocery bags, and other environmentally friendly packaging.
Genecis’ PHA polymer is a breakthrough and an eco-friendly alternative to standard plastic that has similar qualities as oil-based plastic. In proper conditions, PHA dissolves in about a year. It might take as little as eight months in an aquatic domain.

The plastic can dissolve between 6 and 8 weeks in industrial processing settings. Unlike other biodegradable substitutes, PHA has a highly appealing biodegradable character while yet retaining the functions needed in many implementations. Genecis' CEO estimates that her firm can cut emissions of greenhouse gases by 80% through using organic waste as a feedstock, in addition to manufacturing biodegradable plastic and decreasing plastic waste in landfills.
Considerable progress has been made in the production of biodegradable polymers for diverse uses in past years. The creation of the next age of substances, goods, and operations is guided by sustainable development, green innovation, eco-efficiency, and environmental remediation.
Biodegradable polymer substances (also referred to as biocomposites) are of significant importance. They are used worldwide for manufacturing, agribusiness, healthcare, and other purposes. Biodegradable polymers are the foundation of plastic materials that are used in an ever-growing number of applications.
Due to the greater variety of composting alternatives with minimal ecological impact, these biodegradable polymers substantially advance sustainability. Consequently, the opportunity for these environmentally friendly materials is growing at a fast pace, approaching 10%-20% every year.
Due to increasing demand in a wide range of end-user sectors across the world, the world demand for biodegradable polymers is predicted to rise. Despite the fact that biopolymers have been on the market for some years, biodegradable polymers are still regarded to be in the initial stages of the life cycle of a product.
Using PHA plastics can positively impact a wide variety of industries, such as decreasing plastic waste and lowering greenhouse gas emissions. Genecis also creates solutions with a target price that is 30%-40% lower than those already on the marketplace.
Producing PHA using food waste helps eliminate the ecological consequences that come with sole crops like maize, sugars, and potatoes, which are commonly used as the base for bioplastics.
Microorganisms produce a great category of biodegradable materials copolymers known as polyhydroxyalkanoates (PHAs). Consequently, a number of drawbacks prevent them from competing with standard plastic products or serving as perfect biomaterials.
Weak mechanical qualities, high manufacturing costs, restricted functions, instability with traditional thermochemical conversion processes, and sensitivity to heat deterioration are only a few drawbacks. PHAs must be customized to optimize performance in individual applications to overcome these disadvantages.
The research for overcoming the disadvantages is still ongoing. Blending is a fast and convenient way for producing new biodegradable polymeric materials with enhanced qualities while minimizing the disadvantages of the original materials.
The mechanical and physical characteristics of polymer blends may predominantly be modified by selecting the right starting materials and adjusting the blend's mixture and processing procedures. Biodegradable blends also provide PHAs intriguing features, including 100% biodegradability and great biocompatibility.
These blends have piqued attention since they utilize standard technology at a cheap cost and offer a wide variety of applications, including biodegradable polymers and medical instruments, as well as digestible surgical threads.
PHAs' efficiency can be considerably improved by combining PHA with several other biopolymers. By combining PHAs with natural ingredients derived from environmentally friendly materials or other synthesized biodegradable polymers, the substances can be improved.
