  1. Recycling Requirement.  All commercial establishments shall be required to separate designated recyclable materials generated on the premises, which represent greater than five percent by weight of the establishment’s total refuse and shall arrange for the collection for recycling of these materials. These materials must be source separated and kept in a condition to meet minimum market standards.

    In instances where space for storage of the recyclables is limited, the City would allow for an exception to source separation on site, provided that all other options have been exhausted and it is documented in writing to the City prior to the change. Tenants in a commercial building must recycle any designated mandatory recyclable material that represents greater than or equal to 5% by weight of their trash, even if that material is less than 5% of the building’s total trash. Landlords with gross lease arrangements with any or all tenants must either total all tenants’ waste audit figures or do a building-wide waste audit to submit one building plan.

    Landlords offering gross lease arrangements must provide centralized storage containers and recycling service for any designated recyclable material generated in quantities of 5% or more by weight of the refuse of any one tenant. Landlords offering exclusively net lease arrangements must submit the information indicated on the Recycling Plan form and a list of all tenants. 
  2. Program Responsibility.  Program development, implementation and operation shall be the responsibility of each commercial establishment. Each landlord must also submit a Recycling Plan for the building. In cases where the landlord is the contracting agent for refuse disposal in a building, the landlord shares joint responsibility for developing, implementing, and operating the recycling program in conjunction with commercial tenants. 

  3. Recycling Plan.  Each commercial establishment and each landlord of a building housing a commercial establishment must submit a Recycling Plan to the Commissioner of Public Works using hard copy or online forms provided by the City. All establishments must submit an updated plan when requested by the City or within 60 days of any changes to the currently filed plan. These plans, unless otherwise noted, must include:

    A.  Waste audit.  A description of the process by which recyclable materials are to be segregated from the waste, including what materials are to be separated Identification of how the recyclables will be collected and transported to market.

    B.  Information on the process used to notify and educate tenants/employees of the recycling requirements. Recycling haulers and drop-off centers used must have a certificate on file with the City of Cambridge Recycling Division that certifies that they are a bona fide recycler. 

  4. Update to Recycling Plan. In the event that there are any changes to the currently filed Recycling Plan, the commercial establishment and/or landlord must inform the Commissioner of Public Works in writing with 60 days of the change. This includes, but is not limited to, changes in tenants, management companies, elected recycling option, or percentage of recyclable materials by weight in the waste stream.

    The plan shall be submitted by the commercial establishments and its landlord. 

  5. Storage of Designated Recyclable Materials. It shall be the responsibility of the commercial establishment and/or landlord to provide and keep, at its own cost, a sufficient number of containers to hold all designated recyclable materials which may accumulate during the intervals between collection of such recyclable materials. Any such containers, or any designated storage locations, shall not interfere with public or private sidewalks, walkways, driveways, roads, streets, highways, or entrances and exits of public or private buildings shall be in compliance with all applicable laws, including Fire and Health laws. Containers shall be of sufficient quality and design so as to maintain the marketability of the recyclable materials.

Education Program. It shall be the responsibility of all commercial establishments to adequately inform all employees and/or resident users and patrons of the requirements of the recycling program. The required educational program, at a minimum, shall include written instructions to all parties identifying the materials to be recycled, how the materials are to be prepared, how to use the collection system, and updates detailing any changes in the program.
