What can waste gyproc be used for?

Waste gyproc can be recylced into new gyproc. It just can not be buried in landfill. When Gypsum is deprived of O2, such as when it is buried in a landfill, it begins to break down in such a way that casues it to release a toxic gas. I shudder to think how much of that material is buried in Manitoba's & other Canadian landfills.

Can gypsum be used for soil amendment for organic farming?

I also was thinking it could be used as an ingredient in refractory. What do you think?

Hmmmmmm...might want to consult someone more familair with the effects of gypsum mixed with the soil in that fashion. Someone with an agriculture background who knows about what various contaminations of soil will result in. I'd suspect that there emay be some variables involved, depending on the natural occuring chemicals in various soil types.I'd think it would react the same way as it would in landfill, really, but who knows. Not sure what other chemicals are involved, either. Check with some of the manufacturers as to what they add to their board. Just went into my reference materials to find out what is typcially done. If you find that it can be used in that fashion, let us know.

In the long term, that is, the very distant future, we are considering trying to purhcase a demolition firm & get into deconstruction, and getting rid of unreusuable drywall will become an issue for us, I'm sure. Having some alternate uses would be helpful.

Where are you from? I have always been intrested in reuse/recycling. Everything I do is done as much as possible with what people through away. I salvage scrap metal, melt down aluminum, and also am a machinist and carpenter. I recycle paper, cardboard, and over a ton and a half of coffee grounds through my nightcrawlers. Keep in touch with your deconstruction efforts.

We're in Winnipeg. I've always felt that as a society we throw far too much in the trash. 99% of what we toss is reusable in some way. I figure in 20 years we'll be mining old landfills for materials that will become scarce. Not to mention all the contamination that we have caused with our modern (last 100 years) chemical filled trash & toxic metal containing trash.

I agree with you 100% about the amount of usable material that goes to the landfill. I try and do as much as I can here, but it seems its an uphill battle with the attitudes of the people here in my area. I view things in two ways, in manufacturing components make an item, then when the item is tossed out I see it as the components it was made with instead of a piece of junk. How do all of us scavengers/ environmentally contious people get together on this? Forums like these are great, but we need some hands on systems set up through an exchange of ideas and technologies.

Brent, you've got the same view we have. Each item needs to be dealt with as a bunch of components that can be separated, not as a single object. There are really two trains of though in the recycling business, one with breaking down things to their very basic components (plastic chips, glass cullet, steel ingots,etc) and those who prefer to deal with each object & break it down part by part, with the 'waste' being recycled in the traditional manner. Doing things that way will cause less material to enter the recycling stream of raw material, and prevent a complete flooding of the market as more & more people become enviromentally concious. Many plastics really have little $ value as raw materials, and limited markets compared to virgin plastic newly produced, so a flood of more of it isn't going to help the situation any. The type of recyling you're talkign about has been going on for years (the old time scavengers were/are smart people, way ahead of their times!), and has only been recently restricted by cities, municipalities, towns, etc putting up military compound style barb wire topped chainlink fences to keep scavengers out. What are they guarding? A gold mine? (Well, potentially, yes it is a gold mine if worked properly, but they prefer to destroy it all & bury it.) "Legal Liability" is their argument for these fences..."what is someone gets hurt?" Very weak argument, but that is all they can say. The local city landfill has put in a camera system to catch scavengers! Gawd,give me a break! Frankly, in my opinion, we had more being pulled out of landfills before they were fenced off & locked down than we are actually recycling now. Politicians & short sighted busy bodies tend to be a real pain when it comes to actual progress.

I think the security at landfills is more to keep that load of new merchandise from stores out of the hands of the public. A local landfill here had a trucklooad of bicycles still in the boxes dropped off. Any landfill that is open to the public gets visited regularly by my uncle and others, but the large ones at the cities still remain closed to anything being taken out. Ive been a scavenger since I was old enough to ride a bicycle and only plan on do more as time goes on.

Most of the small town & municiple ones in Manitoba are fenced, locked & guarded now. I'm a long time scavenger as well. As a kid my father & I would take out a load & bring a load back...much to my mother's chagrin. He just picked up userul things, motors from washing machines to make things out of, metals, wood, etc. I gravitaed towards old objects & neat 'junk'. He didn;t make his living at it, but I know for a fact that a number of people made their livings off of scavenging the landfill at that time, and not bad livings, either, some far, far better than minimum wage. Isn't it scary how much new merchandise gets tossed out there? it gets written off the stores accounting books, so it now doesn't exist. So worried about it ending up in the 'wrong' hands & comepeting with their own sales....No giving it to underprivilaged, the poor, etc, where it wouldn't be problem competing with the store's normal business. Same goes for fresh food...You don't want to know how many tons of new food & produce hits landfill. They refuse to donate it to soup kitchens, food banks, etc, where it would do some good. They would rather let it rot.

As for the written off, non-perishable stock (non-food), defective merchandise, store returns, etc, we will be setting up a program to keep the material out of the landfill. Unfortunately, we won't be able to sell the items in their original form, for obvious reasons, the same reasons they send it to landfill. Still have a bunch of legal details to work out yet, however.

Let me know how the legal things go and maybe you can help me do the same thing here? I know how much food goes to waste from grocery stores too, and I can't get any of it any more. I had a shock today as I had made a deal to trade a few doghnuts to a tire dealership for their lead wheel wieghts. I got the ok for this yesterday, but when I went to pick them up today, I was told that they were tossed into the dumpster a couple days ago. So, I went dumpster hopping...lol. Too cold to dig to the bottom today, so I just grabbed a garbage bag out of the dumpster that came from the area where they change tires. There was less than a 20 litre pail of garbage, but I melted 2.5 pounds of lead from it. They tossed a couple 20 litre pails of them. I will be going back into the dumpster monday when it's a bit warmer. I might take everything out, since 99% of it is recyclable. All the shops in town do the same thing, its unimaginable to me why.

Starting this spring at the latest, I will be putting an add in the paper to haul peoples unwanteds away, and try to get more commercial waste diverted to my shop. Keep in touch.

I just got a call this morning from a fellow letting me know a buddy of his with a TV repair shop was moving & had rented a trash bin for the weekend. Would have loved to go digging/treasure hunting, and still might tommorrow, but with the weather (-33C with windchill here today) and the fact our warehouse is full, and our van is full, my yard is full at home (to my neighbors' chagrin), my business partner's garage is full, my shed is full, my basement is full, etc, etc, I figured we need to get some decent space before we can accumulate too much more of that type of material. Can be some decent money in it if you know whta you're doing, but it is a fair bit of work dismantling, sorting, etc. Then there is the safe disposal of material that isn't of value. Are you in Yorkton, or outside of Yorkton? I got to Regina occassionally, dealing with a recycler there. Yorkton is how far from Regina, time wise? & From #1 highway west? Any materials you are looking for that you have a use for that have no commercial value? You mentioned coffeegrounds, but I doubt we'd be purposely picking that up, unless you really need more & want to buy them. :)

Sent you an email off list with some information. Should start a new thread dealing with landfills and laws pertaining to them, and other related information.
