Abstract [eng] |
Recycling is the method of changing waste materials into reusable objects. It reduces the consumption of raw materials, energy usage, pollution (from incineration) and pollution (from landfilling) by decreasing the requirement for \"conventional\" waste disposal and lowering gas emissions and by identifying the possibilities to recycles new product. Plastics is considered to be dangerous material because of its low-end disposal rate and it degrades the fertility of the soil. So, the possibilities to recycle plastic wastes are considered n this paper. The wastes from the landfills are collected and the Polyethylene Terephthalate (PET), Polypropylene (PP) and Polysulfone (PSU) plastics are sorted and separated from the collected wastes. These polymers are the most needed semi-crystalline and amorphous thermoplastics in their group in recent times. Waste Plastics are collected, sorted carefully and then grinded. The issues occurred during the process in the industry are eliminated using Lean techniques and Six Sigma concepts. This helps the recyclers to perform the recycling operation in a more efficient manner by reducing the amount of master batch utilization during recycling. Polypropylene (PP)and Polysulfone (PSU) are subjected to melt flow index testing with certain temperatures 230°C and 250° under the load of 2.16 kg to identify the density and melt flow rate and the product strength and viscosity of the polymers are predicted with thus making better possibility in recycling saving resources and cost of production with addition of some reinforcement agents. |
