7 Research-Cleaning Further research shows the benefit of washing clothes is negligible when waste content is <25% File: Effect of cleaning on Processed Material 203%20Subsystems%20Design/Cleaning% 20Sources?rev=0 Cleaning may only be beneficial during specific circumstances Level of soil in clothing & cleaning method When selling complete garments File(s): Textile Washing Trial summary & %20Subsystems%20Design/Cleaning% 20Sources?rev=0

8 Research-Material Handling Material handling accounts for 10-30% of production cost Eliminate unnecessary handling Adds to cost not value of product being sold Factors to Consider: Type of material Quantity Building layout Material flow Associated costs Equipment Personnel Space requirements Transporting Cotton Bales: Truck, train, or ship Between facilities Shipping finished goods Pallet jack or fork truck Within facility

9 Research-Storage of Cotton Bales Information taken from the Joint Cotton Industry Bale Packaging Committee (JCIBPC) Grade A Completely covered with JCIBPC approved packaging Specified number of ties Permanent Bale Identification tag on bale Grade B Completely covered Any holes covered up by approved material Some exposed lint/fibers Identification on bale

10 Research-Long-term effects on Storage of Cotton Bales Information taken from The Journal of Cotton Science Cotton Foundation 2011 Testing Conditions: Tested permeability of moisture on various bale materials: Cotton Burlap Woven polypropylene LLDPE film Hot and humid climate Effects: Increase in yellowing of fibers Minor decrease in grade of fibers Increased risk of permeation from insects Recommended Storage Setting: Humidity level of 50% or less Storage temperature of ~70 The

11 Research - Sorting Manual Textiles are sorted and graded (condition, composition, and color) using the eyesight and common sense of trained employees Throughput: 220,000 lbs sorted by 1 person per year metric from WRAP Cost: ~$900,000 yearly (labor) metrics from assumptions Reached out to SMART, TRA, and Worn Again

12 Research - Sorting (cont.) Semi-automated (FTIR & manual) Textiles are sorted both manually and using automation. The automation (FTIR) can only sort by composition and color, so manual sortation is still required Throughput: 11,000,000 lbs per year metric from WRAP and CPME Cost: ~$540,000 for first year (labor, maintenance, floor space, overhead + investment) metrics from WRAP and CPME Reached out to Valvan and Weiland

13 Research - Sorting (cont.) Automated (NIR) Textiles are sorted both manually and using automation. The automation (NIR) can only sort by composition and color, so manual sortation is still required Throughput and Cost: unknown Similar to FTIR, but possibly higher accuracy Reached out to people on past projects (Textiles4Textiles) New technology but promising through research

14 Research - Shredding UNTHA-America (Charles Hildebrand) Remains Inc. (Kelly Stewart) He has worked with Goodwill in the past Remains works in the textile recycling industry Provided information on 3 machine options Inquired about their processes, data, maintenance, etc. Haven t heard back, but we will look to send a follow up Cut into strips with varying thicknesses Potential throughput values, but still working at getting better information Another contact ---->

15 Research - Shredding (cont.) Hoper Machinery Full Line including : SMART Cutting, feeding, recycling recycling industry machines Inquired about their shredding machines Electric panel, dust collector, SMART members do not actually do any baling machine Specifications and capacity for each machine provided Association that works in the textile Maintenance and operation cost: missing Initial Cost and throughput calculated Advantage: Produces variety of end products recycling Still in contact as they can help in other areas of our research
