Dirty Diapers Used To Grow Mushrooms 97

Posted by samzenpus from the hold-the-mushrooms-please dept.
Zothecula writes While their contents might be considered an environmental hazard by many, disposable diapers themselves pose a more significant problem for the environment. According to the EPA, the average baby will work their way through 8,000 of them before they end up in landfill where they'll take centuries to break down. In an effort to reduce the problem, scientists at Mexico's Autonomous Metropolitan University, Azcapotzalco (UAM-A), have turned used diapers to the task of growing mushrooms.

    Mushrooms used to be grown on horse manure, and I doubt they are very "selective". So this is no surprise.

    However, it is well known to be a bad idea. You do not grow food for human consumption on human feces, because the risk of contamination is too high. Horse manure is ok, as is growing animal fodder on human feces.

    And there are better schemes to get rid of old diapers - since they are rich in high quality cellulose that can be used after a good clean.

"However, the mushrooms could be used as food supplement for cattle, the gel can be used to increase moisture retention in some crops and the plastic can be sent to recycling."

      Nothing new. If you have a compost toilet, you will have encountered spontaneous mushroom growth on your compost pile often enough. Also edible ones, like inkcaps. There is nothing against seeding it with a known mushroom kind. When you do that for your own household, you will know what diseases you have, and you get them anyway or are already resistant to them. Also know that the compost process kills any disease over time, and most diseases within days.

      But I would never add a plastic, chemically poisoned diaper to my compost pile. Most modern diapers are chemical waste and need to be processed as such.

      • Only thermophilic composting can kill diseases, and even then only the material in the core. A composting toilet usually doesn't have the critical mass.
        • You'd be surprised. My compost toilet is a "collector" type, so it is basically a bin with a toilet seat on top (see http://www.thingiverse.com/thi... [thingiverse.com] ) and it must be emptied on a compost pile. So the composting should take place outside the toilet itself. However, the composting process already starts in the toilet and hardly needs any mass at all. It just needs rest and the right ingredients.

    • Try and look up a video of a modern mushroom farm. This is damn near appatizing compared to the way they're normally grown. After I saw it first hand, I started vigorously cleaning all mushrooms I got from the market.

      Who are you, Jon Snow? You know nothing.

      As long as the faeces is properly composted/treated to break down pathogens, its perfectly safe to use for food crops.

      Better yet... create a manufacturing tax... $3 per individual diaper sold. With 95% of the valuable refundable, upon proof of the volume of materials being recycled.

          I expect that the families would refuse to purchase the product at such a price, therefore, the manufacturer will not be able to sell them for $3. The manufacturer will have to meet the recycling requirements, in order to continue to sell the product.

        The problem with detergents is that they *ARE* biodegradable. The phosphate in the detergent encourages algae to grow which causes problems in the rivers.

          There are degrees of biodegradability. Even gold is biodegradable in the longest term (you use some in your biochemistry). As I said, you have a choice of detergents. Pick the right one.

The main reason for this is interfering with biofeedback. The better the diaper the less feedback the baby gets so the less it is inclined to change its behavior.
