Which of the following materials is part of the 12 master categories for "reduce"?

The identification of materials as part of the master categories for "reduce" is centered on the environmental impact and sustainable practices connected to waste management. In the context of this question, glass falls into a category that is often recognized for its recyclability and longevity in the ecosystem. By focusing on reducing glass consumption, we can minimize the environmental footprint associated with its production and disposal.

Reducing glass use emphasizes the importance of rethinking packaging choices, promoting the use of reusable glass containers, and opting for bulk purchasing to decrease overall demand. This aligns with sustainability practices that aim to lower waste generation.

When considering other materials, while plastics, concrete, and food waste all present significant opportunities for reduction, they may not fit neatly into the same master category focused specifically on glass. Each material has distinct implications on waste management strategies, and their reduction strategies may differ based on usage, lifecycle, and recyclability in various contexts.
