Composting Toilet Coconut Coir


We use coconut coir because it’s more sustainable than peat moss and it comes in these compact dehydrated blocks. You can see all of our composting toilet info and videos here: Composting Toilets

    We are getting ready to purchase our coconut coir and see that the Nature’s Footprint blocks that are shown on your website have this California Proposition 65 warning on Walmart’s site. “Warnings:California Proposition 65 Warning: WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.” We assumed this product was completely natural. Do you recommend any other brands that do not have this warning? We are looking forward to our first composting toilet and thought we might as well be as green as possible. Thanks for your great videos!!

      This is text directly from the company website: “Nature’s coconut coir is a 100-percent natural by-product of harvesting coconut. Coir consists of the coarse fibers extracted from the husk on the outer shell of a coconut.” I don’t think there is anything added but they may be required to put that label on because of the country of origin or about a million other reasons. California has insane labeling laws (good, but can be a little vague). The only way to truly know is to contact the company directly for more info. This is the coir we use and have purchased from local hydroponic stores as well but find that Amazon is usually the best pricing and we prefer the dehydrated bricks for storage.

    How long does one 5kg block normally last for you?

    When we first got the toilet we bought this coco coir and loved it except I had never really read (let’s be honest I hadn’t done it at all!) the directions and was trying to hack off chunks of dry coir each time we mixed it up. So, when it was nearing time to order more I happened upon some other brand that came in small blocks. I thought that would be the answer since I could use 3 or 4 and get the right amount. So far, so good. Until about 3 days after and I noticed tiny black bugs all over in the exhaust pipe, and when I opened it to lift out the urine jug they were all over and came out onto the walls. Gross!!! But, we were far from everything and I just dealt with it. I was determined to get some of this again and now have. However, to be fair to the other place-I was about to reorder cat litter that had been recommended by a friend and which we had started using, which is wheat based. When I went on Amazon I saw terrible reviews talking abut little black bugs…Since I started using them around the same time it IS possible that it wasn’t the coco coir. But I am not taking any chances. I am sticking with Coco Coir because I love my composting toilet so much I’ll wait to get back to the camper rather than use a public toilet.
