    Mark Waite Cromwell Tools
  • The decision to provide compostable liners free of charge to residents has greatly contributed to the success of the scheme … the liners assist in keeping odours to a minimum, ensure food waste collection is as easy and convenient as possible for householders as well as making the prices of emptying the caddy into the larger bin as clean as possible.

    Debbie Mansell East Riding of Yorkshire Council
  • Cromwell has already proved with a number of our member companies that they are a reliable and price competitive supplier and we feel sure that the rest of the group companies will reap the benefits of their appointment.
