Have a word with Defra I think from memory chinese tallow is on the list of invasive plants which cannot be imported into the country.

billi in Kerry

 

Me in cork    (Bob is the "Kerryman")

Looks like that it can grow here and nearly all over  upto -15 °    , but its invasive  

A bid windy here   , but perhaps fine ( donot know how much sun/heat is needed to produce the desired quality fruit/nut

Have defra banned oil seed rape yet - that's invasive, isn't it?!

I once considered renting a unit for processing old tyres. But the economics (£10k pm) of running it, potential planning problems, manual handling problems etc put us off.

There is now a plant in South Wales that cryogenically destroys car tyres to recycle the steel and the ex-tyres as rubber crumb

What would you like to know. Anything to do with wood, woodchip, wood pellets for biomass production and generation  Lack of government support I can give you chapter and verse

With regard to hemp it is not illegal to grow in this country but must be grown under licence otherwise it is illegal. Main growing area is in Norfolk.

Yes John, a few locals have been imprisoned for it

hi renewablejohn,
Since I started researching the biomass processing idea it seems to me that either hemp or the chinese tallow tree offer the most potential. The Pyrolysis Reactor seems to be the most efficient and there is a good description and diagram in an earlier posting. Getting No2 fuel(diesel),methanol,wood gas,charcoal and No 6 fuel (Heavy oil but burnable probably in a Turk burner) in significant quantities seems not too difficult once the biomass material has been collected. There appears to be a mechanical way (Cherry /olive tree shaker or an adapted combine harvester)of collecting the ctt seeds which will keep for some time. A Forage harvester could be used for the brash/prunings to keep the ctt plantation in a set format . It all seems to good to be true. I could run the car and aga on no2 fuel,charcoal in the Russian Masonry stove,heat water for the house and underfloor heating with the turk ,a generator with the methanol- the list is endless-I am gobsmacked as to the possibilities- I will wake up in a minute

I think your problem will arise when you start looking to make the Pyrolysis reactor perform as well as being suggested. I have gone down a similar route with woodchip and based on kens musings regarding the vedbil gasifier I have found the Jenbacher gas engines and generator which will burn biogas but the problem is cleaning the gas sufficiently so that the engine will not be damaged in the long term.

For your interest, biogas can be improved by bubbling through water, to scrub out some of the CO2, giving it a higher BTU rating (and less gas, of course). Not sure if this could work on a large scale, though.

To remove SO2, I think they fit a load of wirewool in the gas delivery pipes - the wire wool reacts with the sulphur dioxide, removing it from the gas stream.

Just something I've read - no idea how effective these are.

Bubbling through water does this mean I would have a ready CO2 food supply for the Algae to feed on as described in another thread.
