Solid Waste Institute
The Solid Waste Institute for Sustainability (SWIS) at UT Arlington will combine science, engineering, and social science expertise in developing new methodologies and solutions in order to explore international paths to sustainable waste management. Located in the heart of the Dallas-Fort Worth Metroplex, SWIS has goal to work for better future by developing sustainable solid waste management that incorporate the economy, people and environment which will be beneficial to all cities in Texas, USA, and other countries.
World cities generate about 1.3 billion ton of solid waste per year. This volume is expected to increase to 2.2 billion tonnes by 2025 (World Bank Report, 2012).
Cost increases will be most severe in low-income countries (more than 5-fold increases) and lower-middle income countries (more than 4-fold increases).
Average waste collection rates are directly related to income levels. Low-income countries have low collection rates, around 41%, while high-income countries have higher collection rates averaging 98% (Cointreau, 2008).
