FIBRE SHORTAGE IN SOUTH AFRICA RISKS TO THE BIOMASS SUPPLY FOCUS 2010 Willem Olivier & Andrew McEwan
Sources of Fibre in South Africa • Plantation Roundwood • Plantation Waste • Sawmill Waste • Woodlands • Bush Encroachment
Plantation Areas Pine 672,109 ha E. grandis 277,955 ha E. other 215,377 ha Wattle 177,401ha Total 1,342,844 ha Crickmay and Ass
Roundwood Supply Average Sustainable Supply: Pine Sawlog 4,962 mt Pine Pulpwood 3,731 mt Euc Sawlogs 0,261 mt Euc Pulpwood 9,664 mt Wattle Pulpwood 1,097 mt Total (AD Tons) 19,716 mt Crickmay and Ass
Roundwood Demand Demand in 2008: Pine Sawlog 5,414 mt Pine Pulpwood 3,809mt Euc Sawlogs 0,235 mt Euc Pulpwood 9,554mt Wattle Pulpwood 1,797mt Total (AD Tons) 20,809mt Crickmay and Ass
Supply vs Demand of Roundwood Supply vs Demand (million tons) 35.0 30.0 25.0 20.0 15.0 10.0 5.0 0.0 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 Supply Demand Crickmay and Ass
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 Thank You!
