Biochar Sample Clauses

Biochar and put all Bioenergy section into the Biomass/bioenergy annex rather than here. Accepted, Moved to bioenergy annex 5050 11 20 29 20 29 biochar is not necessarily a stable C-rich co-product it is highly vcombustable after production, some percentage oxidizes on application. Also it comes in very different rates from fast and slow pyrolysis and also creates vastly different amount of C in char under fast and slow. we did an economic analysis considering c prices in ▇▇▇▇▇▇, ▇.▇., ▇. ▇▇▇▇▇▇▇▇, ▇. ▇▇▇▇▇▇▇▇, C.C. Kung, and ▇.▇. ▇▇▇▇▇, "Economics of Biochar Production, Utilisation and GHG Offsets", Biochar for Environmental Management: Science and Technology, Chapter 19, Edited by ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, Earthscan Publications, UK, 341-358, 2009. and in ▇▇▇▇, C.C., and ▇.▇. ▇▇▇▇▇▇, "Economics of Taiwanese Biochar Production, Utilization and GHG Offsets: A Case Study on Taiwanese Rice Fields", 2011. (that paper is under second review at an energy journal) Accepted, Revised for SOD. I think this is captured in the box with the range in estimates of cabron stability in biochar (haf life ranging from 50-10,000 yr). 15963 11 20 3 21 8 Chapter on Biochar is not very clear, some sentences do not seem to be complete. Accepted, Revised for SOD 10244 11 20 4 21 8 Biochar: as stated before, Biochar application is still controversial, potential risks (HAPs, hydrophobicity, …) have to be considered, even more that this is a nearly non-reversible option thus biochar is stable! Biochar can also be made with animal wastes (manure but also bones when processing the animals) Accepted, Revised for SOD. Hydrophobicity seems to be very short term and not likely to be a problem at real rates of application - however, contaminants worth a note. Now added to the box "Standards to ensure that biochar is produced in a way that does not conserve or create toxic contaminants are also required, to regulate deployment." 16559 11 20 4 21 8 Given the small amount of field data showing that biochar is an effective mitigation technique in practice, this section could be shortened very considerably. Accepted, Shortened and revised for SOD. Actually the scale of the opportunity warrants maintaining share of document, but if the document is shrinking…. The stabilisation of carbon is the main element of the abatement from biochar and is both pretty certain and also - importantly - verifiable (comparitively at least) and not reversible with land use change.

Biochar unit- Pilot scale kiln (50 kg/hr) integrated with oxidizer system and provision for kiln flue gas/hot syngas recovery system for wood vinegar production (in procurement process). 5. Steam generator (to be sized to meet steam demand for the pilotRDH digester, and any other future steam demands at BIDF) – At Contract Date a supplier still needs to be appointed. 6. Pilot RDH Digester (30 kg capacity). This also will include farm tanks (4 tanks), and provision for washing and screening unit (in procurement process).
