Non-Roundwood Supply

Approximate Supply from 1,34 mil ha Plantations: Non-spec logs 1,000 mt Bark (excl wattle) 2,000 mt Branches 3,250 mt Total (AD Tons) 6,250 mt

Supply from Processing Plants

  • Sawmills

“Waste”- sawdust, offcuts 2,6 mil tons Bark 0,5 mil tons Estimated Usage 2,0 mil tons Available for bio-energy 1,1 mil tons?

  • Pulpmills

Bark 0,37 mil tons Available for bio-energy Nil

Supply from Woodlands

  • Woodlands

Area - 39 million ha Annual yield and usage not measured

  • Bush encroachment of indigenous

pioneer and alien species

Volumes not measured

Future Markets for Energy Bio-mass

  • South Africa

Biomass competes with cheap coal Export in the short term Eskom e.g. will require 28 mil tons air- dry biomass to generate 10% electricity

  • Europe and North America

Growth in demand expected up to 30% pa over next 10 years

Summary

  • No additional roundwood available for bio-

energy

  • To produce bio-energy from roundwood

fibre must be bought in competion with current processors

  • Bio-mass will be available from non-

roundwood products, bush encroachment and woodlands. Volumes unknown

  • The economy will dictate volumes used
