Local wildlife trust bog had contractors strimming and raking  up with  hay rakes.  Bagging the stuff in dumpy bags (was about 20 bags)

 

Looked very ineffiecent for large area

 

They may of had to pay a commercial green waste site for disposal as they are funny about "enriching" the site.

Finding a home for arisings from habitat maintenance is a problem the wildlife trusts  just don't seem to want to address, on heathland sites they bale, scrape and dump stuff in the treeline and that's no long term solution. Burning (swaling) would have been the way to promote new shoots in the past.

 

For over 20 years now I have advocated making use of it for heat and co production of biochar but get no interest.

There is/was a experimental composting/fuel biomass enterprise they were talking about taking it too locally.

Unsure if anything came of it

 

Stuff it was making was abit like eco briquettes

 

Theres some pics here  of previous versions:

Thanks I'll have a read tomorrow

Whta do you make of it?

 

Idea is all the bracken on the welsh hilsides would be harvested ....

I didn't seem able to find much detail, it seemed to be a well intentioned vertically integrated system making use of all the components of the waste, the volatile solids element ( that bit which heats up  heaps of mulched greenery) producing methane and then all the residue being dried and compressed into pellets/pucks/briquettes for combustion.

 

I suspect, like our charcoal, heat and power project, the capital cost escalates to make commercialisation non viable. We have seen in field devices for making straw pucks fail after initial field trials because even though the straw is dry the forces are too great for a mobile machine. Not to mention trying to harvest on a steep rocky hillside.

 

All that energy creamed off in the biogas process would still be available as heat if the whole biomass were burned and less problems dewatering and drying the residue. They seem to be hooked on the holy grail of generating electricity from biomass (as we were indirectly).

 

I'm all for utilising waste heat from such a process for buildings but with a simpler pyrolysis and co producing the char as a saleable product for soil amelioration.
