SECTION A. General description of project activity A.1 Title of the project activity Title: Letaba Biomass to Energy Project Version: 6 Date: 5 May 2009 A.2. Description of the project activity PROJECT DESIGN DOCUMENT FORM (GS-VER-PDD) Voluntary Offset Projects - Version 01 This template shall not be altered. It shall be completed without modifying/adding headings or logo, format or font. page 3 Letaba Estates is a large citrus farm near the town of Tzaneen in the Limpopo Province of South Africa. The farm grows, sells and exports fruit and fruit juice. The fruit juice is made onsite in a juicing plant that needs electricity and steam to operate. In the processing of citrus fruit most of the waste fruit peels are dried for cattle feed in peel driers fired by coal in adjacent combustion chambers and a portion of the peels is land-filled. Since 1961 when the plant opened, the steam requirement has been met from large coal-fired boilers installed onsite. Until recently the installed steam capacity was 31 tonnes per hour from four coal fired boilers, and at present the capacity is still 26 tonnes per hour from three coal fired boilers. The coal is sourced from 380 kilometres away in Middelburg in the province of Mpumalanga. Tzaneen is also home to a thriving forestry industry and there are several sawmills around town. In addition to much wood, large quantities of biomass waste is produced in the form of woodchips and sawdust. The wood chips have a market value and are freely available in a spot market, especially as Silicone Smelters in Polokwane (traditionally a large buyer) is no longer doing so 1 . The main supplier of wood chips and sawdust will be Matumi Sawmills (Pty) Ltd, a company that never before used to chip or sell its waste wood. There is thus no danger of a leakage through wood chips being taken out of the market. The sawdust produced by these sawmills seldom finds any useful large scale application and in several places has been disposed on what have become sizeable heaps (informal solid waste disposal sites). In total there are between 15 and 20 producers of sawdust of whom about a third possess large sawdust heaps in excess of 5 metres where methane is created. The total annual production of sawdust within a 49 kilometre radius from Letaba Estates is estimated at 35 000 tonnes per annum of which about a third is stock-piled on waste dumps in excess of five metres high. These high stockpiles listed in A.4.1.4 below are conservatively estimated to contain 175 000 tonnes of sawdust at 65% moisture. Transport leakage is not considered. The reason for this is that the only source of potential leakage is transport emissions and the effect of the project will clearly be a positive leakage - the coal used in the baseline was transported from 380 kilometres away in Middelburg while the sawdust/wood chips will at most be transported 49 kilometres from the landfill sites to Letaba. As a most conservative approach it will require 4.33 tonnes of wet saw dust at 65% moisture to displace 1 tonne of coal. If this is sourced from the furthest saw mill (49km) then the effective distance will be 4.33*49km=212km for saw dust, which is still far less than the 380km for the coal transport. The moisture content of wood chips will be 40% at most and so the positive leakage on a fuel switch to wood chips will be even greater. A sawdust drier fuelled by sawdust/woodchips may be installed at the site of the prime supplier, Matumi. This if viable will increase the positive leakage by making the fuel lighter. The feedstock would again be biomass and lead to no emissions. Project Activity Interventions 1 The wood chips at most sawmills and specifically at Matumi, the chosen fuel supplier, are made from waste wood (off-cuts) produced in the sawmills. Matumi acquired a chipper specifically for this project. At sawmills in the area, smoke can always be seen as the prevalent method to dispose of waste wood is to burn it. There is thus no competing use for the biomass wood chips or the sawdust.
