Waste Buddy allows local authorities to specify up to 24 collection and treatment services. Of these eight can be 8 kerbside services, 4 CA site activities, 2 bring site and 4 commercial waste collection activities. These can feed either directly to the market, specified by contracts, or through 4 treatment facilities or 4 landfills. Each of these service can be selected or hidden for ease of use.
Each service has a standardised form, similar for all services, but with some customisation for treatment and landfill services.
Even though spreadsheet based, the tool automatically integrates the services behind the scene, to allocate waste from one service to another or to a treatment facility. In essence waste flows through different modules of the model, and attracts the appropriate costs.
The figure illustrates how Waste Buddy works for garden waste collected at the household.
- An amount of garden waste is estimated, based on expected yield from a household. This garden waste is taken from the total waste arisings based on the yield and the number of households receiving the service
- A collection service, with vehicles and crew are applied, together with the gate fee contract from the composting contractor.
- If the Council operate the in-vessel composting plant then the collected material is send to a treatment module. Otherwise it is sent to market for the agreed gate fee.
- In the case of energy recovery plants, there will be process loss and some residual material landfilled.
Waste Buddy can be configured for all treatment facilities
