Reduce, reuse, and recycle are the three Rs of sustainable practice. Of these three actions, reduce is the most straightforward, with the goal of minimizing energy use, raw material consumption, and dead-end waste production. On the other hand, recycle and reuse have multiple facets. For example, in last month’s Topical Collection, “Sustainable ceramic and glass raw materials,” there were several examples of materials produced for one purpose being “recycled” into raw materials for other purposes. Could this practice be considered reuse? Perhaps.
