Usually, modern plastics are forming a useless waste of our natural resources when they’ve hit the landfills. The Sierra Resins SR Series of bioplastics is giving us and the world around us the tools required for breaking down the highly complex molecular structure of plastics so it can return into our world as vital products like water, carbon dioxide, water, and salts. For the sake of argument, take also a look at this video with some opposing views:
Despite everyone’s best efforts, a vast majority of plastic produced annually ends up in landfills, for what could be thousands of years. As a result, environmental sustainability is compromised. Sustainability knows one single simple principle: All the things that we need for our well-being and survival is depending on our natural habitat and environment.
Sustainability is about creating and maintaining conditions in which nature and humans can co-exist. Sustainability is also important to ensure that we will be able to continually have the resources and water required for the protection of our environment and human health. With this in mind, years of development and testing have gone into the SR Series of bioplastics.
All plastics begin their life as a natural molecule. As the plastic decomposes in a landfill it creates salt, water, carbon dioxide, and methane, a natural gas and one of the most energy-efficient and cleanest burning fuels known. In a modern landfill, methane capturing is not just mandated by regulations, it is a big part of the business model. That methane fuel is worth a lot of money. Our polymer additive significantly accelerates methane creation and maximizes the return on investment. By making our domestic landfills more productive, we can begin to reduce our dependence on imported fuel.
Over 500 billion pounds of plastics are consumed each year – plastic bottles, shopping bags, packaging materials and the like. Some plastics can last thousands of years in the environment. This is what spurred the creation of the Sierra Resins SR Series polymer additive.
Degradable or bioplastic resins and polymers are tested to see if the producers’ claims are trustworthy. The tests use both mass loss and gaseous measurement techniques to determine the rate of biodegradation. Mass loss studies determine the degradation degree which is a more conservative way than gas-based measurement because solid particles may be adding weight to the end results. Degradation, however, can also be observed visually as mass reduction, embrittlement, or a discoloration.
Sierra Resins SR-Series biopolymer molded products break down in most landfill environments. The SR Series works with most plastics and foams and was designed to allow Planet Earth’s hungry microbes to release enzymes that in effect eat plastic products that bloat our landfills.
separate collection of polymers
Plastic has become the most common material since the beginning of the 20th century and modern life is unthinkable without it. As a result of this growth, the total share of plastic waste is getting more and more extensive. Nearly all types of plastics can be recycled, however, the extent to which they are recycled depends upon technical, economic and logistic factors. As a valuable and finite resource, the optimum recovery route for most plastic items at the ‘end-of-life’ is to be recycled, preferably back into a product that can then be recycled again and again.
We enhance a separate collection of polymers and/or their recovery from bulk collection in specific waste streams and supply the best quality recycled polymers available to the plastic processing industry.
Many companies supply high quality recycled polymers in different optical and physical properties suitable as input for injection molding, film- and sheet extrusion companies.
