RRT Design & Construction

This seminar will introduce topics regarding methods for converting solid waste into an engineered feedstock for combustion and gasification. Over the past four decades engineers and scientists have used the technologies of screening, size reduction, separation and classification integrated into complex material handling systems. Improved understanding of the heterogeneous nature of solid waste continues to be applied for the correct selection and engineering of the material handling equipment and processing equipment. This seminar will outline key engineering principles that are applied toward solid waste processing facility design.

The fastest growing area of solid waste management is the field of recycling. This seminar will discuss the specifications for recovered materials from recycling plants; what will the market buy, at what price and in what form and for what use. Today over 25% of our waste stream is recycled compared to less than 5% before 1985. Community based curbside collection programs numbered under 300 in 1989, they are now over 10,000 in United States. As a $40 billion a year industry, the field of solid waste management has fully embraced recycling as a cost-effective and environmentally beneficial process. This seminar will discuss some of the pressing needs for new technologies and advancements to improve the economics of how recyclables are recovered and how to better prepare them for reuse in manufacturing.
