Project overview
Cascadia is helping Bay Area Rapid Transit (BART) determine waste targets for this year and for future years—which includes conducting visual waste audits, estimating fill rates and material composition, setting baseline waste targets, and creating waste diversion strategies.
Approach and impact
As part of this work, we wanted to provide BART a snapshot of the types of waste containers available to riders—including details such as colors, labels and locations. This inventory will help BART understand how to create a more uniform collection system for its riders.
The data collection process included recording bin data for almost 600 bins at 45 out of BART’s 50 stations. Staff also noted bin fullness, the types of waste being thrown out—including areas where recycling bins were not available—and signs associated with the bins.
Data analysis revealed opportunities for BART to improve contamination rates at stations, including providing signage and collocating waste, recycling, and composting bins for ease of use by passengers. These recommendations will support standardization of the waste, recycling, and compost bins available at BART stations—which will not only improve contamination rates for BART, but also improve the ease with which passengers can dispose of their waste as they ride transit. We’re excited to continue working with BART to develop their waste targets and find new and innovative ways to meet them.
