Look out for toilet paper wrapped in paper not plastic and choose a paper that is either recycled; nonbleached; or at least FSC sustainably sourced (look for the FSC symbol)
OR Green Cane and smartass both home deliver a big box of toilet paper made from the residue from sugar canes after they’ve been crushed to extract sugar. Normally this would be a waste product. Check the number of sheets per roll to work out the beset value. I believe most toilet papers are around 200 sheets per roll. A 2ply guilt free fluffy white soft experience.
Both Green Cane and smartass also do tissues. And they are also both available at organic stores. Check them out online for stockists.
