Wood waste disposal?................

Postby Leveller2911 » Thu Nov 03, 2016 7:40 pm

Evening all, We dispose of our wood waste and assorted building rubbish via an REL (Rear End Loader) 11 yd Skip which we have emptied every 6 weeks or so. We have our extractor rigged up to the REL so all of our wood waste goes straight inot the skip. Wood waste accounts for around 85% of the waste and just about all of it is Hardwood so no good for equestrian use. Its now getting expensive and the skip guy is struggling to find anywhere locally to tip it. All the local waste transfer stations are getting arsy because its wood shavings/dust,glass etc and they struggle to separate it all for recycling.

The skip guy now has a 75 mile (minimum) round trip to tip and its now gonna cost us £285 for him to empty it and we need a solution.

My question is how do you guys get rid of your wood waste?. We have looked into a woodburner ,big jobby that stands outside ,you feed it and it blows hot air into the workshop but it wouldn't get used for 6 months of the year and the waste would build up. We have also considered a briquette machine but the problme there is we are small scale and haven't got the time to keep feeding the hopper.

We offered to kep the glass waste separate and when theres a sizable amount get a skip to put it in so its easity sorted at the WTS but again its another added cost.

Any ideas or advice would be welcomed............

:lol: Yeah nice idea Murdoch but if we saved it all up we would drwon in it by the time Bonfire night comes round. Some little sh*t would more than likely torch before hand ... We have a river 100 m away so could just put the extractor hose out the door and let the wind take it all.

I buy skips for my MDF (dust and offcuts), £192 for an 8yard skip, I get through more than I'd like, 8-10 a year ish.

All the shavings/chips from proper wood (all Oak and Walnut) go to the local horses. Why don't your horsey types like yours?

For one reason or another I can't find any other means of getting shot of the MDF so I'd be very interested in what you find out. Either the big burny thing can't deal with MDF (not hot enough?) or the big burny thing is massively expensive, or the big burny thing needs to be inside and I don't have space!

Hardwoods are no good for horses as they can give them breathing problems, theres a name for it but I can't remember what it is. We had horsey people in each week until we stopped using softwood then they weren't interested. I know Oak is not good for horses as when they wee in it it reacts with the tanins and gives off a gas which can also be harmful.

You can get a bug burny thing that sits outside and blows hot air inside, Insurance companies like them because there is no naked flame in the building . The down side is they are £5k minimum and you can easily add another £1.5k on flue as our roof is easily 15 m to the ridge..I'm gonna do as much research as I can and will post back but always interested in what you guys do . Looked into briquette machines but they need feeding constantly and the auto feed ones are around £30k .. :lol:

My sawdust goes to a local dude who uses it for his horses.............He's the local vet who specialises in horses! Ho hum, he knows it's Oak and Walnut, so I've always assumed is more qualified than me to decide :-)

I want a MDF burny thing, that will heat the workshop in winter, heat a pool in summer, and cost £100 to purchase!

If you can separate the shavings then try contacting local: Smoke houses, Poultry breeders, pig farmers etc. It's worth a try as they collect and could reduce the problem. I don't do that much joinery but when I do, I can get rid of as much shavings as I can make through a local poultry club (softwood mainly though).

All of our shavings are taken by a local broiler chicken farmer. They use them to scatter on the floor in the chicken sheds. Unlike horses it doesn't matter if it's hardwood shavings or mdf dust, he takes it all, comes every couple of weeks. All our solid wood offcuts are sold for wood burners. Mdf offcuts go in the heater. There's only 4 of us so we may not produce the same volume of waste as you.

I have an Irish bloke who comes and takes mine oak,tulip,mdf for their horses, they aren't bothered, they even pay me £1 per bag.
Another kitchen company I know and do some specials for, were having the same problem as you. they were
using a skip a week at £165, the skip company came to them and said they couldn't put any sawdust or chippings
in anymore because it could cause an explosion in their yard when emptied. They went and bought a Talbot wood
burner paid about £12k for it, 100% tax relief, its paid for itself in a year. They burn all year round as they shut all the
vents inside in the summer and open a vent to the outside so all the heat goes their. worth considering?

I was going to say the same as paul .. you can still burn in the summer .. just don't use the heat !

Mark Numbers just put a thread up with a woodshredd/briquette machine combo ..
lots of people will buy wood to burn at home these days, as the heating prices keep rising !

The local farmer will take any sawdust/chips here, he brings me ton bags to fill and takes them away.

I have plenty of people wanting the oak chips for smoking, cant keep them all happy!. I chop the plank ends off before machining and keep the oak chips as clean as possible, its not too bad because its nearly all oak. I also use a separate extractor to keep the oak chips as clean as possible now.

Off cuts and kindling get burned in the home woodburner. Would be nice to use it as workshop heating in the winter but isnt possible at the moment.

Maybe a bit pricey but maybe look at woodgas generators, burn and use the electricity generated in the shop and i think you maybe able to get FIT on what you put into the grid.
I reckon at some point there will Biochar plants being developed and all organic waste will be charred and getting rid of wood waste will be cheap.

There are biochar plants in the US as Aus and NZ already on farms mainly. BIOCHAR is amazing stuff not got around to making my own yet but ill get around to it.

Have a google its called Terra Preta in the Amazon area where it was discoverd meters in depth, its a way of locking carbon back into earth and when used as soil ammendment (has to activated with compost first). From what I have seen on the net plants, fruit and veg grown in this stuff is like putting them on steroids!!

Need to get back to work ill link some stuff later.

Great replies guys and will do some more digging.

Interested in the Woodgas Generators Jon ,sounds like a really good concept and does sound expensive but I'll have a look.

I was having a quick look online last night and came across these guys. Its similar to what we do now as all our machines extract into the REL.

http://www.plattsrecycling.co.uk/

Getting rid of offcuts/old frames etc is not a problem because we have an old boy take all of it away for his woodburner.

Had a look at a briquette machine and exterior woodburner but they both need feeding regular , costs are around £15k upwards and time is money. Looking at an automated system and they start off at around £35-40k and its just not viable for us.

Keep em coming guys............... :)

Have you thought about local tradesmen with woodburners who would take it off you? I have a burner and struggle to create enough waste for the "cold spell" - I have it lit from October to April (ish). During the summer I just stack up all the offcuts/bags of shavings etc.

I only burn extractor shavings and mdf/chipboard/plywood in my workshop burner - solid timber is reserved for the home woodburner.

Cheers

Karl
