Recycling Management

Polymers are designed to exhibit durability and strength, however, an unfortunate consequence is that they create environmental pollution after use, i.e., synthetic polymers do not easily degrade in the outdoor environment and accumulate at dump sites causing litter. The required properties for the end use of synthetic polymers results in their relative resistance to environmental degradation, which includes biodegradation. 

The recycling of plastics waste provides an ecologically acceptable way of reutilising the energy content of the waste. The plastics processing operation is damaging to the environment and inefficient if the polymer composition of the waste is unknown. It is necessary to conserve and dispose of plastics waste as there is no alternative solution, hence it should be considered as a resource disposal techniques depend on the type of waste and location. 

With ever-increasing oil prices, recycled plastics are becoming an economical alternative for the production of a wide range of commodity plastic parts. Polyolefinic polymers, such as polyethylene (PE) and polypropylene (PP), contain approximately 14% hydrogen these materials could provide the hydrogen required for thermal coprocessing with biomass, which could lead to an increase of the liquid production of oligomers or short chain polymeric materials.

Guiding principles, such as the recycling management system or natural raw materials for example, had in the past a considerable effect on the irmovation processes and the public debate in the field of chemicals and/or substance economy. It must be presumed that this will remain the case in the future too,... 

In the past twenty years many legal provisions have been created to regulate substance flows (recycling management systems, waste management, electrical and automotive recycling). In many instances these laws exphcitly contain threshold values for certain substances or even ban certain substances. They are thus very effective on the use of these substances in production processes. This is also tme for threshold values of chlorinated compounds in industrial waste, the ban on certain heavy metals in the automotive industry and substance-related requirements for waste water from the textile industry (Annexe 38 of Waste Water Ordinance ).

An efficient recycling management of filtrates and mother liquor is also important in this case. Filtrates and mother Uqnor can be recirculated after optional concentration for the preparation of the initial reactant solntions, for example, the aluminum trihydrate dissolving step. It can be reentered into the process not only for the dilution of sodium silicate solution, but also directly into the hydrogel precipitation vessel [169].

Electronic identification can be attached to materials or products that reveal information about material handling and waste management. Por example, plastic bottles used in consumer products usually have an identification symbol that can be used in recycling management.
