Quick answer

Select a compost machine based on waste flow, density, operating schedule and site conditions. 250, 500 and 1000 L describe single-chamber volume; model selection considers daily waste quantity and operating patterns.

Describing the waste flow

Observe peak periods as well as normal days. Collection times, material types and quantities support preliminary assessment. Restaurant seats or hotel beds alone do not describe actual waste flow.

S72 models

S72L250F, S72L500F and S72KL1F are single-chamber options of 250 L, 500 L and 1000 L. Compare dimensions, installed power and empty/full weights together. Installed power does not equal continuous energy consumption.

Installation and service

Plan bin access, discharge area, maintenance clearance and electrical infrastructure together. Equipment fitting within floor dimensions is not sufficient on its own. Assess safe operator movement and output handling.

Scope of a quotation

Evaluate equipment price together with installation, site works, training, service and data services. GreBotics includes data connections and reports free for the first year with machine purchase. Process and energy reports help you track operating data over time.

Litres describe chamber volume. Installed power is not constant consumption. Confirm installation scope in the current quotation.

Practical checklist

  • Do not equate litres with kilograms per day.
  • Distinguish installed power from measured energy.
  • Obtain written installation and data-service scope.
