Information for property managers

Information for your property manager or whomever contracts directly with a garbage and recycling company.

  1. Composting service for office spaces is often shared by multiple tenants in one building.
  2. Estimating your service needs and cost will require a conversation with all the potential participants, to determine how much food waste will be produced on a weekly basis. The property manager can facilitate this conversation with tenants and the garbage and recycling company.
  3. The City of Portland does not set garbage, recycling, or composting rates – businesses choose a garbage and recycling company to work with and negotiate the type and cost of service directly with the company.
  4. Businesses often find it helpful to request bids for the proposed composting service from their own garbage and recycling company, as well as a few others doing business in Portland.
  5. Garbage and recycling companies can help you estimate what service level – the size of your containers and number of times they're emptied – you will need. There is a service level for almost every situation.
