Twist’s biodegradable sponges are made from sustainably harvested, biodegradeable wood cellulose. The company makes sure that more than 99 percent of its waste gets reused in production. They also package their products in paper instead of the usual plastic, which further cuts the use of nonrenewable resources. The naturally tough loofah side of the sponge does every bit as much work as plastic scrubbers. Find them at your local natural grocery; about $5 for two sponges.
