During IPL 9, RCB initiated a Waste-to-Recycled-Kits program where special collection bins were set up in different stands across Chinnaswamy Stadium to collect used plastic bottles from fans in the audience. The bins were set up in the stadium from the match preceding the Green Match.
These post-consumer PET bottles were recycled to develop the Green jerseys for RCB players for IPL 10. The waste is processed using a patented chemical recycling technology, where in the PET waste is depolymerized by dissolving it into glycol. The glycol is then filtered out and the depolymerized PET is again polymerized to convert it into the yarn. This 100% recycled polyester yarn is then used for manufacturing the kits.
• Quantity of waste which is required to spin a standard unit of the recycled yarn. For making 1 kg of recycled yarn, we require 1.3 kg of bottles.
• Details of energy consumption, carbon emission, and any other savings during the processing of the recycled yarn from waste. Energy consumption 16.27 MJ/Kg against 69.4 MJ/Kg for Virgin polyester (77% saving) Water consumption 8 lit/kg against 60 lit/ kg for virgin polyester (86% saving) Saves around 0.7 barrels of oil and 0.20 meter cube of landfill by recycling every 1 Ton of PET waste
• Quantity of bottles used for manufacturing the green jerseys. Approximately 11000 PET bottles weighing 250 kg were used for developing filament yarn (100% recycled polyester) to manufacture the kits.
Waste Management at Stadium
RCB has initiated a comprehensive waste management program for all the home matches at the Chinnaswamy stadium. RCB believes in leading by example and have therefore implemented a program to ensure that the 8-10 tons of waste generated in each match is managed effectively, to create a positive impact on the environment. Some key highlights include:
• Installation of separate bin system in all the stands to promote waste segregation at source into Dry and Wet waste
• Promotion of waste segregation practice amongst fans through on-site awareness posters and videos
• Volunteers to help with primary segregation and fan awareness
• All the collected waste is then sent for recycling (Dry Waste) and composting (Wet Waste) accordingly
Statistics including the total quantity of waste generated, amount of waste recycled and composted and the total reduction in greenhouse gas emissions as a result will be reported for all the 7 home matches.
