A construction polymer made from multi-layer packaging waste has been developed at the Ogarev Mordovia State University (MSU). This was reported by the university's press service.
Secondary polyethylene and TetraPak multi-layer packaging waste were used to create the polymer composition.
Compared to analogues, the development has improved elastic-strength characteristics - increased strength, modulus of elasticity in tension of products and a decrease in cost by two to three times due to the reuse of waste.
The first stage of creating the new material was melting the polyethylene at low pressure and a temperature of 150°. In the second stage, crushed pieces of packaging were added. The resulting mixture was cooled in a tray at room temperature.
The use of recycled materials is one of the steps towards reducing production costs, efficient use of resources and improving the environmental situation. For example, the invention of scientists at our university can be used for the production of engineering products, which will create conditions for the conscious use of polyethylene and TetraPak packaging.
The new processing method differs from similar technologies. It excludes the process of separating TetraPak packaging into aluminum, cardboard and polyethylene.
Earlier www1.ru reported that Russian scientists created ceramics from coal ash of thermal power plants.
