Waste Flow Analysis and Modeling

We develop powerful waste stream scenario models that forecast likely policy impacts to support strategic solid waste planning.

Cascadia prepares sophisticated, configurable modeling and decision-making tools to support communities in managing waste and recycling and growing a circular economy. Our tool development team works flexibly across platforms—including Power BI, Google Forms, ArcGIS, QuickBase, and others—to collect and manage data from a variety of sources and in a variety of formats. Our tools are designed to reveal both big-picture trends and granular insights that support planners in maximizing diversion, minimizing costs, and reducing greenhouse gas emissions across the whole product lifecycle.

Examples of our support include:

  • Waste generation models
  • Feedstock projections and analysis
  • Policy and programming cost-benefit models (e.g. EPR, single-use disposables bans, etc.)
  • Waste-related greenhouse gas emissions inventories
