Proposed Workshop
Integrated Waste Management
Summary: A workshop is proposed to give the attendees a background in Integrated Waste Management (IWM). The workshop involves the following areas of study: waste generation and composition, waste characterization, collection, processing, recycling, landfills, thermal conversion and composting. The lectures are argmented with a series of hands on activities ranging from conducting a waste audit to developing a recycling plan.
Background: “All creatures, human included, constantly make decisions about what to use and what to throw away. A chimpanzee knows that the inside of the banana is good, and that the peel is not, and throws it away. A paramecium uses certain high-energy organic molecules and discharges its products after having extracted the energy in the carbon-carbon or carbon-hydrogen bonds. And humans buy a can of soft drink with the full understanding that the can will become waste. Waste is a consequence of everyday life- of all creatures”. Vesilind et. al. (2001)
Day-By-Day Topics
Day 1 - Waste Generation and Composition
Knowledge of the quantities of solid waste generated, separated for recycling, and collected for further processing or disposal is of fundamental importance to all aspects of solid waste management. The purpose of this days lecture is explore the importance of waste quantities, measures and methods used to quantify quantities, generation rates and the factors affecting them, types and quantities of materials recovered from MSW, and quantities of household hazardous waste.
Hands on activity: Attendees will broken into groups of no more than 3 individuals. One member of each group will have been asked previously to bring in a weeks worth of trash including recyclables. The attendees will sort their waste. Data from all groups will be combined to form a waste audit.
Day 2 - Waste Characterization, Collection and Transfer Stations
The purpose of this days lecture is to introduce the physical, chemical and biological properties of MSW and to the transformations that can affect the form and composition of MSW. This background will be followed with a discussion of the collection of solid waste and the use of transfer stations.
Hands on activity: Attendees in groups will compact different types of waste into a mold of known volume using different amounts of energy. This information will be used along with the waste audit to estimate the volume that the waste will potentially occupy.
Day 3 - Waste Processing and Recycling
The purpose of this days lecture is to discuss the recovery of separated materials, the separation and processing of solid waste components, and the transformation processes used to alter the form of the waste and to recover useful products. In addition, utilization of both community curbside and recycling centers for post-consumer materials found in MSW will be discussed.
Hands on activity: Attendees will develop a design for a MRF to process waste identified from the waste audit developed in the first days work.
Day 4 - Landfills
This days lecture will discuss the safe and reliable long-term disposal of solid waste residues that are not recycled, that remain after processing at a materials recovery facility, or that remain after the recovery of conversion products and/or energy.
Hands on activity: Attendees will develop a recycling plan to capture recyclable materials identified in the waste audit.
Day 5 - Thermal Conversion and Composting
The function of thermal processing for both reducing the volume of MSW and energy recovery is discussed. Topics discussed are fundamentals of thermal processing, combustion systems, pyrolysis and gasification systems, and environmental controls. In addition, biological processes such as aerobic and anaerobic composting will be discussed.
Hands on activity: Attendees will construct a compost pile for use by an individual home.
