Estimates of the final amount and final disposition of materials generated in the Construction and Demolition waste stream measured in total mass of each material. Traditional C&D materials included are concrete, asphalt pavement, asphalt shingles, bricks and clay, metal, wood, and gypsum drywall. Non-traditional materials in this stream include cardboard, organics, carpet, glass, plastic, and fines. The estimates are based on generation amounts described in the EPA SMM Facts and Figures reports. The method used to estimate final disposition is called CDDpath. This dataset is associated with the following publication: Townsend, T., W. Ingwersen, B. Niblick, P. Jain, and J. Wally. CDDPath: A method for quantifying the loss and recovery of construction and demolition debris in the United States. WASTE MANAGEMENT. Elsevier Science Ltd, New York, NY, USA, 84: 302-309, (2019).

This is USDA-ARS data from the publication: "Performance of a cotton gin machine that removes plastic contamination from seed cotton." The study was conducted during the Fall of 2020 with continued data analysis thru September 2021. Plastic contamination is the most pressing issue for the U.S. cotton industry today. Due to this problem, U.S. cotton has lost the 7 cents per pound premium it brought on international cotton markets. Plastic contaminants are often introduced prior to ginning, but cotton gin machinery can tear and shred the plastics so that they become more difficult to remove. A cotton gin machine developed and used to combat the plastic contamination problem in Chinese cotton was tested to compare its performance at removing typical plastics found in U.S. cotton to that of conventional cotton gin seed cotton cleaners.
