Choosing recycled toilet paper and toilet tissue is a great way to do your part for the environment—especially if you buy for a large office or school. And selecting recycled doesn't mean you have to sacrifice quality. All of these recycled toilet paper and toilet tissue options will still be strong, soft, and absorbent. They're just made from post-consumer materials, which helps capture and reuse waste that otherwise would end up in landfills.
You don't have to spend a lot of extra money to do good.
Recycled products, especially high-quality ones—used to come with a premium price. But today's competition has brought recycled toilet paper and toilet tissue down to about the same price point as non-recycled. In fact, we used to only carry one or two different brands of recycled toilet paper. Today? More than ten. That means you have more products to choose from, prices are lower, and you can help the planet without hurting your bottom line.
Recycled toilet paper and toilet tissue is available in regular and industrial-sized rolls.
If you're purchasing recycled toilet paper and toilet tissue for your home, we have rolls designed to fit into standard TP holders. We also carry jumbo and industrial rolls for large offices, schools, and government buildings. These large-capacity rolls last for a long time, even in restrooms with heavy foot traffic, so you won't have to replace them as often. Depending on what type of dispensers you're using, you can even have coreless backup rolls automatically slide into place when needed.
Recycled toilet paper and toilet tissue is also available with other sustainable options.
Even if you're buying toilet paper made from 70% post-consumer content or 100% recycled fiber, you can still do more. Look for additional features like toilet tissue whitened without chlorine bleaching.
