On a totally different note, my Mom was one of the bloggers contacted by John at Envirokats. We like that this litter is reusable and leaves less waste in the landfills. We also like that the processing isn’t hard on the land. We are however concerned about the potential for toxins in ingestion and also any potential off gassing from the product.
Tire crumbs can be made into many different things. In rubber flooring they are considered green, although if you really want a healthy house, they recommend looking up how much off-gassing goes on. These are the VOCs in any given product. We are not at all sure why one would have less VOCs than another given that they are made of basically the same material. This is the main concern when using these for children’s play grounds.
When used in gardens, a big concern is if something leaches into the land. The most common thing to leach into the land in a garden is zinc. On the West Coast where land is zinc deficient in general this is actually a good thing. On the East Coast where there is plenty of the mineral, it’s not so good as plants can be overwhelmed by it.
Finally we have to worry about ingestion. Again, there are questions about whether this is safe. We are wondering if any of the bloggers have done any research into tire crumbs to use for other things and what they have found.
We think this is a great idea in that recycling tires is an important thing. We really like that this company has found a way to take something that is clogging up the landfills and creates toxins when burned and is using it for something else. We like the idea of reusable cat litter (okay so the Woman isn’t thrilled with the idea of having to wash it out). However, we have concerns about the health. We’ve been emailing with Jan over at the Funny Farm as well and hope that she will post anything she has learned too–although she is concerned about all the confusing information.
Our best understanding is that the jury is still out about using tire crumbs but we’d love it if someone who has studied it more can send us links to offer their perspective. We think that John is trying to do something really good. We also think that the idea of reusable cat litter (so that it doesn’t just go to a landfill in a plastic bag) is a really good idea too.
