Recycling bags: 16.8% compost,  55.1% recycling, and 28.1% trash.\"><\/p>\n\n\n\n<p><strong>Here are some major insights the we gained:\u00a0<\/strong><\/p>\n\n\n\n<p><strong>Compost: <\/strong>On average, 93% of waste in compost bags belonged in the compost (the rest being contaminants). This is a great ratio of compost to contaminants! Food waste was the largest compost subcategory.&nbsp;<\/p>\n\n\n\n<p><strong>Recycling:<\/strong> On average, 63% of waste in recycling bags was recyclable and paper\/cardboard was the largest recycling subcategory. There were a lot of dirty paper cups in recycling bags. Instead, these should be put in compost bins if they\u2019re compostable, or trash bins if they\u2019re not compostable. There was also a lot of liquid left in recyclable plastic cups. This liquid can contaminate other recyclable materials like cardboard. Be sure to empty your cups and bottles before recycling!&nbsp;<\/p>\n\n\n\n<p><strong>Trash:<\/strong> On average, 36% of waste in trash bags actually belonged in the trash and flexible plastics were the largest trash subcategory. We found a lot of compostables in the trash. While we still encourage the norm of \u201cwhen in doubt, throw it out,\u201d we can all still do a better job identifying recyclables and compostables to keep them out of the trash stream.<\/p>\n\n\n\n<p>This data from this waste audit also helped to inform decisions for our new waste signage we are designing, potential changes in bin locations, and future waste education and engagement opportunities. We\u2019ll be conducting more waste audits in the future so stay tuned for future results. In the meantime, make sure your recyclables are empty, clean, and dry, and to compost all your leftover food if you have access to a compost bin!\u00a0<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/lh7-us.googleusercontent.com\/hM09RsIRX-u4PVhCKDrjs25G8keP784ZLy9G3UDauHnsmlem1UZpkP2oNcKBgT_Rt-OdwdnpPDIPUp2lb5CUtyf9wxujkrE9xYto1UOy_Z7fsAaieF7q11r6VPbwR-aQM2QxRTTSVn5r2i5aLGqGPU4\" width=\"400\" height=\"532\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Sustainability Coordinator Jacqui Moy Waste Diversion Fellow, Ria Wipperfurth suited up for our waste audit.
