  1. By pyrolysing it. Fixed carbon in woody waste is about 15% of the dry matter in woody waste, less in non lignin containing stuff. At lower temperatures there is more yield but the tars in the char are less recalcitrant but still fairly long lasting. The term coined for using this char to store carbon in the soil long term, by a late ex-pat, Peter Read, is biochar. The challenge is to make this biochar from high moisture content green waste and utilise the heat in the process.
  2. non sequitur anyway what makes you think I think current government in UK is any good at regulation, which is what we were discussing. In fact everything points to that growth in wealth disparity since 1970 is going the way to favour people with wealth aspirations by removing resources from regulators.
  3. This is patently not so, without regulation we would have far more pollution, not to mention slavery and other abuses of workers.
  4. It seems to me that local government attracts a lot of people looking for security and avoiding working but that's another matter. As to green waste; I think that too came as a result of someone in a LA realising that while there was no mandate to collect it once it was collected and sent to a composting facility it counted as recycling and in one hit put the recycling percentage up. As I have mentioned here before I think, once collected, green waste would be better used by fixing the carbon in it rather than composing it and returning the carbon to the atmosphere
  5. Yes a properly regulated market can but as I said government takes a while to adapt whereas there/s always somone looking for a wrinkle to make some easy money without concern for the consequences for others.
  6. I feel for your sentiment but it was an ill thought out directive that gave a financial reward in the form of recycling credits for stuff that was exported. This went entirely against the ethos of dealing with waste locally. It didn't take much for the entrepreneurial types to see they could collect rubbish, export it anywhere and claim these credits whereas the legitimate recycling industry had to actually do some recycling to claim theirs. Such is the capitalist system we live in, it allows any innovation then takes a while to react and regulate the new activity once someone realises it is done at a cost to the commons we all depend on. In the meantime fortunes have been made. Just consider how long we have had a two, or more, bin system, 20 years yet? Also consider that segregation near to where the final user wishes to discard something keeps the "resource" cleaner and purer, once you start mixing it it becomes of less value to the recycler. e.g. originally glass bottles were kept separate by my local waste collection but many people did not feel they should be responsible for keeping it separate, the council relented and allowed glass bottles of any colour, tins, paper and plastic food containers all in one bin. This immediately devalued the glass cullet but worse it contaminated the paper and card with shards of glass after sorting and damaged the re pulping machines, making the waste paper fraction less valuable and reduced the yield. However it increased the total claimed recycling and the chief executive was awarded a number of tens of thousand to his already corpulent salary for the increased performance.
  7. Probably and I doubt I ever ate a whole one. From a very distant memory it was a sweet taste wasn't it? My mother talked about kids eating them during rationing when anything sweet was sought out.
  8. Yes Yes That's plain ambiguous, yes you get more volume for the same weight so it looks a bigger load.
  9. We started designing an incinerator for nappies for a care home, about 20 years ago, it all looked promising and there's mostly only aliphatic (straight chain plastics) in them, the sodium polyacrylate that is used to absorb the liquid shouldn't be a problem either, it is apparently a problem in landfill.. The main problem would be the effect of all that moisture on the combustion conditions of the burner.
  10. I did say unsorted municipal waste and you had implied that you had sorted yours into combustibles. Mind your virgin wood ash is now contaminated with whatever minor chemicals went into your combustibles and as your woodburner was not designed to retain all the massflow for a couple of seconds at above 1200C and then exhausting them through a wet scrubber AND/OR an electrostatic precipitator a number of nasties could have been emitted, which a properly managed incinerator would have trapped.
  11. trouble is incinerating unsorted municipal waste still leaves 30% of the mass as ash which has to be landfilled. Mind burning plastics in a properly regulated incinerator to steam plant for generating electricity seems more sensible than producing poor quality recycled paraphernalia like boardwalks and fencing which will be a future disposal problem, or sending them halfway around the word to be thrown in the sea. All the time we burn oil for transport why begrudge the small fraction used for plastics production? It is foreseeing the consequences of plastics use that's the problem,
  12. RHS wisley definitely grew from a leylandii cone. What you have to consider is both crosses occur so a male Nootka and female macrocarpa produce one leylandii hybrid and a male macrocarpa and female nootka produce another, one may be sterile but the other not.
  13. @shavey perhaps without the space
  14. good stuff re asthma but yew berry snotty gogs are not poisonous, the seed in the middle is but better safe than sorry.
  15. I'm not sure I like the idea of the neighbour provoking the fell but good on the TO for relaxing the TPO in this instance
  16. Good use for the tracked MEWP. It was a lapsed pollard and while reduction was an option it probably was as well to bite the bullet and get the expense done with.
  17. I bought one for 60 quid delivered from Paddocks for use with the Eder winch. it easily holds 1tonne in our sandy soil. It's two flat bars with 4 5/8" clearance holes and 6 2' 5/8 pegs with an eye welded on, all plated. Just set it out as a Vee with a shackle at the apex and hammer the pegs in. Unfortunately it is not listed now.
  18. Possibly one of the gaultheria, shallon was used for pheasant cover, invasive.
  19. I've not found very small burners in narrow boats, Morso Squirrel seemed popular and that takes over a 10" log. I tried to interest my local boatyard in nets of logettes from slabwood passed through a branch logger. The costs didn't compare well with coal. Also at this time of year the stove needs to be kept running constantly and kept in overnight. I would consider the small logs from a branch logger for my own use if I had access to one and was able to handle IBCs or potato boxes of them straight from machine to seasoned in store to fire with no handling in between.
  20. Try Steve (alternatorman portsmouth) 02392368419. These engines are used in canal boats and straters seem to be about 130 quid but Steve may rebuild yours.
  21. There are two reasons why a bit of warmth helps, one is that the dehumidifier removes water from the air by passing it over a cold surface to condense it, if it's too cold the heat exchanger ices up and stops working, this causes mine to pause and defrost. The other is that you are circulating moist air into the dehumidifier, condensing it and sending warmer, drier air out but air holds more moisture when it is warm, so you need to circulate less warm air to get the same drying. Air at freezing point holds a tenth of the moisture of air at 40C.
  22. Probably worth considering both.
  23. I'm not sure that would give out enough heat but then you only have to get the temperature up to about 22C so that a dehumidifier like @Paddy1000111 suggests in a wardrobe sized enclosure will dry most things. Boots and chainsaw trousers from drenched to wearable using a 200W dehumidifier overnight, in an alcove that previously housed an old gas boiler in the kitchen and will get 10 litres of water out in 24hrs. As the water is condensed the energy used by the dehumidifier is added to heat the small space, mine has the central heating pipes running through it.
  24. I test for spark then compression then this. Not something I've come across with saws but the Stihl BT45 drills were forever clogging their mufflers and it was the spark arrestor that clogged.
  25. It was always stone to hone and file to sharpen but last time I felled with an axe was 1983 and I cheated for all but the last 10 blows for the camera.
