Mellow Compost Lab

 Compost Bins Descriptions 

We describe the physical properties, types, geometry and volume size of our compost bins.


The Mellow Compost Lab  (MCL) has a total capacity of 1520L and five compost bins of three different types. The  compost bins parameters and attributes are important in the MCL project to provide a baseline and  consistency in measurements, data analysis, insights and error management.
