EN3015 Plastic and E Waste Management Syllabus:
EN3015 Plastic and E Waste Management Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To know various sources of plastics waste generation and the segregation methods for recycling the plastics and recycling codes of commodity and engineering plastics
To learn about primary recycling techniques with examples/case studies.
To understand the recycling of various commodity and engineering plastics.
UNIT I SOURCES AND CHARACTERIZATION
Plastic and environment value additions, global policy, regulations, waste energy management. Waste treatment of various plastic plants, estimations of power requirement & efficiency of size reduction operation of plastics, environment pollution aspects. Need for recycling – Sorting and segregation of waste – Plastics identification- Plastics Production and composition – Plastics waste – Composition, quantities and disposal alternatives.
UNIT II PRIMARY RECYCLING OF PLASTIC WASTES
Primary recycling – Equipment’s for primary recycling. Specific recycling techniques – PE films, PP battery case – Crushing and separation – PET films.
UNIT III SECONDARY RECYCLING OF PLASTIC WASTES
Recycling of plastics from urban waste – rheology, density, mechanical behavior. Secondary recycling Plastics wastes containing paper – hydrolytic treatment – processing methods – processing of mixed plastics waste – household waste – industrial sector – TPO based materials.
UNIIT IV TERTIARY RECYCLING OF PLASTIC WASTES
Use of recyclable plastics in motor vehicles – recoverable materials – disposal of residuals – recyclable plastic components – virgin and recycled HDPE – Fluorinated and unfluorinated HDPE – fuel tanks. Tertiary recycling – Reactors used – Advantages – Dry method wet method – use of recyclable plastics in automobiles.
UNIT V E WASTE MANAGEMENT
E- waste; composition and generation. Global context in e- waste; E-waste pollutants, E waste hazardous properties, Effects of pollutant (E- waste) on human health and surrounding environment, domestic e-waste disposal, Basic principles of E waste management, Component of E waste management, Technologies for recovery of resources from electronic waste, resource recovery potential of e-waste, steps in recycling and recovery of materialsmechanical processing, technologies for recovery of materials, occupational and environmental health perspectives of recycling e-waste in India
TOTAL: 45 PERIODS
