Hard to easily compare GHG as some last longer in the atmosphere than others, though most of them turn into CO2 anyway (a good reason to stop combusting thing).]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253445#Comment_253445 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253445#Comment_253445 Sat, 28 Jan 2017 23:07:55 +0000 ringi Posted By: SteamyTeaExcept most is now captured and turned into electricity (and CO2).

Yes maybe to burning chemically-polluted timber (chipboards/melamine etc) if the flue gases can indeed be scrubbed efectively - tho it sounds crazy to have fuelled gas burners in the flue for that purpose.

No to general waste burning esp plastics. These are much more valuable as a precious resource of high-potential long-chain hydrocarbons for all sorts of future use, than for atomising to lowest possible potential by burning as fuel.
They should be stockpiled aka landfill until costs and techniques make it feasible, even necessary, to quarry/automatically sort the stores in lieu of more oil drilling.

Once we stop thinking of oil-based hydrocarbons (whether new/virgin or old/recycled as suggested) as an energy source, but primarily as feedstock for miriad other vital purposes,
at the same time as renewable/solar energy continues its ever-accelerating trajectory to dominance/sufficiency,
then we'll find that pumping in energy to medium-potential recycled 'raw' material, to convert it to high-potential pure feedstock,
will be a best-possible use for solar energy,
just as we agree that plastic insulation is a best-possible use for petroleum hydrocarbons today.

This will be systematic recycling such as we've still not conceived of, even when we call it 'upcycling'.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253476#Comment_253476 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253476#Comment_253476 Mon, 30 Jan 2017 09:55:29 +0000 orangemannot With a bit of genetic modification.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253496#Comment_253496 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=253496#Comment_253496 Mon, 30 Jan 2017 16:12:39 +0000 fostertom Posted By: orangemannotgrow or synthasize hydrocarbons & plasticsThat will be another, poss biological way of capturing into materials the solar energy necessary to create high-potential long-chain pure feedstocks.

But what's the raw material - bulk C and H - which the growing or synthesising process transforms?

Most of the waste we ship to Scandinavia for combustion is purely for economic reasons - it's cheaper to ship it than burn it (and a lot cheaper than burying it).

Their waste to energy plants are desperately short of feedstock (as everyone has got better at recycling and they are not seeing the volumes the plants were predicted to consume)

In the UK we aren't so good, so building energy from waste plants (in the shadow of coal fired plants) is still feasible to do as we have enough crap to use and also to sell - obviously the balance will shift but still doomed as UK recycling gets "better"

Partly before we don't have anything to use the low grade heat for that is left after some generation is done.

Not as bad as it seems, as most of the heat can be recovered from the flue gases after they have been super-heated by the gas burners. The recovered heat can be put into their heating networks, that would otherwise have been heated with a gas boiler.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=258697#Comment_258697 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14864&Focus=258697#Comment_258697 Wed, 07 Jun 2017 20:52:14 +0100 Mike1
"In winter, this part of the Alps has the worst fine-particle pollution in France... the main cause is a renewable energy source with an environmentally-friendly reputation - the humble wood-burning stove...

The latest surveys show that between 60% and 80% of fine-particle pollution here comes from wood-burning stoves and fireplaces in people's homes," says Vincent Hazout, who recently organised a demonstration calling for action against air pollution. It rallied 1,000 people in Sallanches."
