Syllabus
Introduction to waste production in different sectors such as domestic, industrial and agriculture etc. What is Waste? Waste Management Hierarchy and 3R Principle of Reduce, Reuse and Recycle. Waste minimization –reducing waste generation at source. Principles of Waste Utilization and introduction waste as a resource and recovery of this resource from waste. Types of waste (organic, inorganic, hazardous, infectious etc.). Characterization & Classification of waste –agrobased, forest residues, industrial waste (hazardous and non-hazardous), municipal solid waste, plastic waste, biomedical waste, e-waste etc. Concept of–Zero Waste–Zero Pollution–Zero Landfill Three general methods of attaining zero pollution. Economics of zero pollution.
Technologies for Waste Utilization and cleaner production processes–aerobic digestion and anaerobic digestion composting, vermin-composting, briquetting/pelletization. Waste-to-Energy –combustion, gasification, pyrolysis, biomethanation, bio-refineries. Landfill gas generation, collection conversion to fuels for useful energy applications-engine, compressors, burners, lamps etc. Waste recycling to recover resources –Value added chemicals from acid gas, novel adsorbents from fly-ash, red mud etc. Clean Technologies and their applications in production processes.
Case studies & Success Stories of waste utilization in different industrial sectors: Manufacturing process, pollution sources, waste characterization, waste reduction/reuse/recovery and final treatment methods for–Pulp and Paper, Sugar, Distillery, Tannery, Dairy, Textile, Cement Manufacture, Thermal Power Plant, Dye and Dye Intermediates, pharmaceuticals and any other industry of importance.
Course Objectives
- At the end of the course the students are expected to be able to define and describe waste, its categories, the waste chain, the situation in flanders, hazardous waste, the waste hierarchy.
- At the end of the course the students are expected to be able to describe, explain the principles, and other relevant aspects of waste recycling, recovery and reuse
- At the end of the course the students are expected to be able to select the best treatment option for a given waste/rest stream
- At the end of the course the students are expected to be able to explain the environmental implications of each treatment.
Course Outcomes
After completing the course, the students should be able to: <br />(1) Describe and analyze waste streams in terms of resource recovery <br />(2) Identify and describe suitable resource recovery processes from waste streams <br />(3) Compare and evaluate sustainable resource recovery processes from waste streams
