PLASTICS RECYCLING & WASTE MANAGEMENT

PLASTICS WASTE MANAGEMENT (PWM) 1.        Sources 2.      Collection segregation 3.      Identification by simple methods 4.      Techniques employed for its separation Plastics have made remarkable contribution in almost every field of human activity today- Medical, transportation, agriculture, piping, electrical and heat insulation, Manufacturing of household and electronic goods, packaging, furniture and other items of daily or specific use. WHY PLASTICS ARE USED Plastics are widely used because of their light weight nature, durability, non-breakability, transparency as well as opacity, potential for diverse application, and low price. CATERGORY OF PLASTICS 1.      RECYCLABLE PLASTICS (Thermoplastics):   PET, HDPE, PVC, LDPE, PP, PS etc. 2.      NON-RECYLABLE PLASTICS (Thermoset and others):   Multilayer & laminated plast...

ROTATIONAL MOULDING MACHINE

Image
  ROTATIONAL MOULDING INTRODUCTION ·          Rotational molding is a process of making hollow articles. ·          The part is formed inside a closed female mold. ·          In this process the mold rotates biaxially during heating and cooling cycle. ·          Rotational molded pieces are stress free because the pieces are produced without any external pressure. ·          The ability to manufacture large containers of capacity 30,000 gallons as well as small items like golf ball is responsible for the growth of this process. ·          The Process requires relatively in expensive equipment and exerts on only small pressure on the material being formed. PRINCIPLE ·          The principle...
