What exactly is “Zero Waste”?

Zero Waste is a philosophy and a functional framework. It moves us away from the “Take-Make-Waste” linear model and toward a system where every discarded material becomes a resource for something else.

The internationally recognized definition involves managing products and processes to systematically avoid and eliminate the volume and toxicity of waste. In short: If it can’t be reduced, reused, repaired, rebuilt, refurbished, refinished, resold, recycled, or composted, then it should be restricted, redesigned, or removed from production.

Circular Economy

Keeping the Loop Closed

A circular economy is the “engine” that makes zero waste possible. It’s an economic system aimed at eliminating waste and the continual use of resources.

Example InitiativeCircular Benefit
Tool LibrariesReduces the need for every household to own (and eventually discard) power tools.
Right-to-Repair LawsEnsures electronics stay in use longer, keeping rare earth metals out of the “ghost stream.”
Industrial SymbiosisOne factory’s “waste” (like heat or scrap metal) becomes a neighbor factory’s “fuel” or raw material.
These are just a few examples of ways our communities and governments can and will continue to move toward waste neutrality.

Why “Zero”?

We call it Zero Waste for the same reason a company strives for “Zero Workplace Injuries” and carbon neutrality We might not hit the absolute integer of zero tomorrow, but aiming for anything less means we’re planning for failure. By designing waste out of the system, we’re building a more resilient, localized economy.
