Understanding Mass Balance Bookkeeping: A Key to Sustainable Supply Chains
In today’s era of heightened environmental awareness, mass balance bookkeeping has emerged as a vital tool for companies aiming to track sustainability in their supply chains. This method allows businesses to account for the flow of materials through their systems, especially when dealing with mixed sources—such as renewable and non-renewable raw materials—within the same production processes. Mass balance bookkeeping works on the principle of input-output tracking. For every unit of certified or sustainable input material added to the system, a corresponding amount of output can be claimed as sustainable, even if physically mixed with non-sustainable inputs. This approach is particularly useful in industries like chemicals, packaging, and biofuels, where separating sustainable from conventional resources is not feasible at the molecular level. One of the key benefits of mass balance bookkeeping is its flexibility. It allows companies to gradually transition toward more sustai...
