Habitat for Humanity Metro-West/Greater Worcester needed a new method to estimate landfill diversion from their ReStore sales. The nonprofit uses diversion numbers to apply for grants that support them financially. We developed a methodology to find the average weight of inventory being purchased by customers. We compiled data by physically weighing items to create departmental averages. We created a calculator on Microsoft Excel to allow ReStores to calculate how many pounds of inventory they diverted from the landfill. We crafted training documentation on how to use and customize the calculator to each unique ReStore’s needs. The results of our project are sustainable, simple, and customizable within the organization.
