Posted by: Tim Clarke on 1/27/04 Title: Disposable, non-biodegradable Horticultural cubes
Postnum: 217 EntryID:1026
Hi My Company has an invention called Mechanical Soil ( http://www.timothyclarke.com ) It is a reusable, washable cube(10yrs+) designed to replace the tens of millions(30+ est) of disposable, nonbiodegradable(nonrecycleble) stonewool horticultural cubes which are thrown into Canadian (& US, Aus, China etc...) Landfills every year. So I have heard, in Holland and other Northern European countries, they have already brought in laws to deal with this, due to the large scale of Greenhouse Horticulture and the limitations of Landfill space in these countries. I noticed that legislative steps have been taken here in Canada to make sure that Gyproc (Plasterboard disposal) is properly separated due to the nonbiodegradable/inert nature of that product. My question and concern is this: "Will the Canada/North America ever acknowledge this waste and environmental impact being caused by rockwool disposal in the Greenhouse industry as has been done with Gyproc in the Construction Industry and who would be responsible for writing and tabling/requesting such new legislation?" Thank you very much for you time, please feel free to call or write if you have any questions. Sincerely,

Well, around here you cant tell that there are any environmental laws. They haul all the gyproc waste to the landfill along with lead wheel weights, and other things. I am a scrap metal dealer and recycler of other materials, trying to do as much as I can to recycle as much as possible. One problem I run into is when trying to buy scrap from farmers who won't sell it to me, but will hire a cat to come in a burry it. The only environmental laws that excist in this country, excist to make a few government departments rich. I have been trying to find a use for waste gyproc, but no luck so far.

I do some greenhouse planting and like your product, although I never use rockwool, and am trying to get away from using peatmoss. I use worm castings for everything since I can't find a market for them.

That's interesting Brent, I guess the recycling infrastructure here in Canada isn't as developed as I thought. One of the Greenhouse owners told me that since we can make our plastic cubes for the same price as the rockwool ones, we could sell them also as a disposable option, it's funny how it is sometimes a preferred option to dispose rather than recycle. The worm castings are a great organic fertilizer. If you could dry the stuff it would probabley be a great product in the Hydroponics industry, the most common organic hydroponic fertilizer I know of right now is Seaweed, which they condense and sell. Bat Guano is another one that is seen in a dried form. Thanks for the reply and best wishes for your business. Tim, Richmond, B.C.

People find it way to easy to just through things away. I drives me crazy when a tire shop tells me they just tossed 3 20 litre pails of wheel weights in the dumpster. If it would quit snowing and get above -20, I would dive back into that dumpster on a rescue mission.

There is no shortage of worm castings where you are, but no one knows what they are here, and they rather dump chemical on everything. I did tests with casting tea to grow plants in chicken grit(crushed granite), with a NPK of 1-1-1, it grew great cucmbers, beens, peas and radishes. I can dry the castings, but still have no market for them here, so I will use them myself and have all the advantages.
