Program Overview<\/h3>\r\nThe DC Department of Parks and Recreation (DPR) supports a Community Compost Cooperative Network<\/a>, which encompasses 56 sites spanning each of the District of Columbia\u2019s eight wards. In addition to 36 sites located at DPR gardens, one is at a national park, six are at schools, and 13 are located at partner gardens. Each garden is run as a cooperative, and individuals using the site join by taking a brief training and agreeing to contribute. The program is largely run and managed by volunteers. Each site has one to three volunteer managers, who train their co-op members, organize work days as needed, and are responsible for quality control. Each co-op site can accommodate around 100 active composters or one ton of food scraps per month. There are currently about 1,000 people composting around 20 tons per month. Materials accepted are primarily fruit and vegetable scraps, garden trimmings, and small amounts of bread and shredded paper.\r\n\r\nThe program began in 2013. It started with a few years at one garden. DPR spent several years on community outreach, building community trust, and developing a cooperative model to avoid volunteer burnout.\r\n\r\nThe program has inspired similar community compost networks in other cities, such as Philadelphia\u2019s Community Compost Network<\/a>.","":null,"settings":""}},{"acf_fc_layout":"layout_anchor","_acfe_flexible_toggle":null,"component_anchor":{"title":"Municipal Motivation"}},{"acf_fc_layout":"layout_wysiwyg","_acfe_flexible_toggle":null,"component_wysiwyg":{"content":"

Municipal Motivation<\/h3>\r\nWhen the program began, DPR was having to buy soil amendments. At the same time, the haphazard way that garden members were piling up their gardening trimmings was creating rodent habitats. By enclosing the composting process and producing onsite compost, DPR was able to solve two problems at once.","":null,"settings":""}},{"acf_fc_layout":"layout_image_grid","_acfe_flexible_toggle":null,"component_image_grid":{"repeater":true,"images":null,"images_repeater":[{"image":31758,"caption":"Volunteer day at compost co-op site.

Composting Activity<\/h3>\r\nEach site uses a 3-bin composting system called the Compost Knox that was designed by Urban Farm Plans (which no longer exists). The system was designed to withstand \u201cabuse,\u201d such as youth climbing on the bins. Each bin, which is a 4-foot cube, is locked with a combination lock to prevent passersby from throwing trash in them. Those interested in joining the program agree to volunteer at least one hour per month for at least nine months of the year and have to participate in a short training session to learn the do\u2019s and don\u2019ts of composting. Once completed, the co-op managers provide the combination lock numbers, and the co-op members earn the right to drop off their food scraps at their convenience. The co-op managers organize workdays such as to 1) flip material from bin one to bin two or three, or 2) screen finished compost.","":null,"settings":""}},{"acf_fc_layout":"layout_anchor","_acfe_flexible_toggle":null,"component_anchor":{"title":"Divulgaci\u00f3n y educaci\u00f3n"}},{"acf_fc_layout":"layout_wysiwyg","_acfe_flexible_toggle":null,"component_wysiwyg":{"content":"

Divulgaci\u00f3n y educaci\u00f3n<\/h3>\r\nMany of the Community Compost Cooperative Network\u2019s site managers have been recruited from the DC Urban Gardeners (DUG) network, a volunteer organization promoting urban agriculture, food justice, and sustainability resources for the greater DC area. For many years, as the program was starting up, DPR offered a 30-hour Urban Master Composter Certificate Course<\/a>.\r\n\r\nEach bin has a metal sign affixed to it explaining what it is and how to get involved. DPR also set up a listserv specifically for site managers to communicate with each other.\r\n\r\nFor onboarding new members of each cooperative site, DPR created a training guide for managers. The guide covers steps such as the importance of oxygen, moisture, and mixing food scraps with \u201cbrowns\u201d (mostly fall leaves and wood chips). It also covers site orientation and how to compost in a 3-bin system.\r\n\r\nDPR maintains a website on the program along with an mapa interactivo<\/a> to facilitate finding a site. Each site on the map lists the address and how to contact the site manager.","":null,"settings":""}},{"acf_fc_layout":"layout_anchor","_acfe_flexible_toggle":null,"component_anchor":{"title":"Compost Markets"}},{"acf_fc_layout":"layout_wysiwyg","_acfe_flexible_toggle":null,"component_wysiwyg":{"content":"

Some of the bins were constructed by a contractor (at $5,000 each) and some were built by volunteers on community bin build days. Tumbler sifters cost $50 in materials to construct. DPR hired a contractor to build some of these for $500 each. Not every site has a tumbler sifter. The only paid staff is Joshua Singer, who works a fraction of his time on the program.\r\n\r\nThe benefits to the District have included: building a culture of compost know-how at the neighborhood and school level (along with a culture of shared responsibility), reducing rodent issues at gardens, enhancing local soils for local food production, and facilitating community volunteerism and connection.","":null,"settings":""}},{"acf_fc_layout":"layout_anchor","_acfe_flexible_toggle":null,"component_anchor":{"title":"Financiamiento"}},{"acf_fc_layout":"layout_wysiwyg","_acfe_flexible_toggle":null,"component_wysiwyg":{"content":"

Financiamiento<\/h3>\r\nA Sustainable DC grant of $25,000 enabled the purchase of the wood to build 20 of the 3-bin systems. Those were built with volunteers. Then DPR secured more funding and was able to build about half of the additional bins with contractors and about half with volunteers. One school raised $1,000 with its Parent-Teacher Association (DPR paid for the tools).","":null,"settings":""}},{"acf_fc_layout":"layout_anchor","_acfe_flexible_toggle":null,"component_anchor":{"title":"Lessons Learned"}},{"acf_fc_layout":"layout_wysiwyg","_acfe_flexible_toggle":null,"component_wysiwyg":{"content":"
