CREATING THE CASSAVA REVOLUTION Cassava Processors
DADTCO General DADTCO established in 2002. Shareholders; people with Africa experience who share the belief that economic development comes from private businesses with the aim to improve income standards of African Farmers. MISSION OPERATIONS APPROACH HOW Create the cassava revolution In Africa and then to the rest of the World Reach as many smallholder farmers as possible Provide a guaranteed market to farmers Create new processing technologies Make quality products, matching buyer s needs Substitute expensive imports Export grade A starch to Europe and the USA.
Why cassava? An edible root crop with about 23% starch content (82% on dry matter basis). Root is stable in the ground for up to 2-3 years. Roots start to degrade as soon as harvested. Approximately 9 12 months cycle with high yields (10 to 60 MT per HA) Can be planted and harvested throughout the year. Easy to grow, drought tolerant, low fertilizers, pesticides and maintenance demand. Cassava has many advantages for starch production: High level of purity. Excellent thickening characteristics. A neutral bland taste. Desirable textural characteristics. *A cheap crop containing a high concentration of starch that can surpass the properties of other starches (maize, wheat, sweet potato, and rice).
Global distribution of cassava Cassava prefers ambient temperatures > 30 C and grows particularly well in the agro-climatic conditions found in most parts of Sub-Saharan Africa.

Why cassava projects fail in Africa Perishability Roots degenerate the moment they are harvested Transportation time too long Smallholder crop Lack of regular root supplies Farmers widely scattered, small volumes and bad feeder roads Transport costs 65-75% fruit water adds to transport costs Transport costs too high
Why cassava projects fail in Africa No Suitable processing technology Either centralized, large economy of scale or Cottage type industries Both resulting in starch losses Quality issues Cyanide in the roots, lack of validation methods Non food grade processing Plantation farming not feasible Crop too labour intensive at replanting time High yielding crop only when personal care is provided. Over-invoicing by importers Import monopolies and price cartels Coastal bound, makes local souring unattractive
DADTCO Solution; 5 essential technologies Demand driven cassava farmers management Full release of all starch from plant cells Removal of fibres and non starch substances Removal of all cyanide containing contents Reducing moisture content (drying) Roots Supply AMPU, same day processing ASPU (Mobile Refinery Unit) DADTCO enzymatic process Mobile Drying/ Flash Drying Production of cyanide free Starch Grade B with 1,8% fibres
DADTCO Solution; same day processing 1. Wet processing part Decentralized Releases starch Removes non starch Extends shelf life 2. Dry processing part Centralized Close to cheap energy sources Urban area, markets
Why Decentralized Processing Same day processing No post harvest losses Better quality starch Transport costs To transport cake instead of roots is three times more efficient Pollution Centralized fruit water causes pollution. Close to farmers fields Management regular supply workable
Demand driven cassava farmers management Root supply management is a core skill: Alliances with local governments, farmers, research institutes and agricultural organisations. Use of advanced information technology systems, media, barcoding and GPS/GIS systems. Communication and information sharing with farmers. Team of mobilizers in the field organizing farmers Cash payments DADTCO ID cards Track & Trace of all root supplies *Farmers have a guaranteed market and direct payment upon delivery
Building trust Processing on farmer s door step; Awareness campaigns involving radio messages, chiefs, farm leaders and local administrators Organize farmers sessions and identify farmers Registration of cassava farmers and issuing of ID cards Introduce improved agricultural practices and follow-up Issuing of a purchase guarantee for next year Organize a cassava platform with research, farmers and extension services. Guaranteed market; farmers know the price at planting date
DADTCO supports farmers with know-how Use clean tools Select healthy plants Mobilizers spread know-how on 4 most limiting factors in cassava farming: 1. Access to disease free high yielding varieties 2. Production, stocking, treatment and planting of stems. 3. Replanting dead stems. 4. Increase plant density Store under shade for 10 days Make 30 cm long cuttings Cut off the top and basal parts of the stems Make sure the cuttings have 5 to 8 nodes
Socio-economic IMPACT one AMPU Local economy $1,200,000 per year in the villages amongst 4000 farmer families. $300 per family additional money on a cash income of not more than $100 -$300. Foreign exchange savings per AMPU $3,800,000 foreign exchange savings per year, replacing imported wheat and/or malted barley. Building alliances Creating market attracts other investments Building bridges between multinationals and local farmers
Autonomous Mobile Processing Unit (AMPU) AMPU processing The AMPU is assembled in a 45 foot high cube container The AMPU moves around a cassava growing region, stays 3 to 4 months at one platform(site) and moves in rotation to 4 or 3 sites per year. Roots are processed into cake with 98% released starch 50% reduction of water. Cassava cake properly packaged and stored, can be kept for at least 6 months under ambient conditions. Washing & peeling Chopping Rasping Dewatering by decanter Cassava cake 52% moisture *If the farmer cannot come to the factory lets bring the factory to the farmers
AMPU Capacity An AMPU has a capacity of 5 MT cassava roots per hour On a 2 shift basis one AMPU will process 80 MT roots per day or 24 000 MT per annum. This in turn is equivalent to: o 13 000 MT Cassava Cake o 12 000 MT Cassava Starch Cake o 7 000 MT Cassava Flour (HQCF) o 6 500 MT Starch Grade B. o 6 500 MT Starch Grade A o 6 700 MT Mixed syrups AMPU Cassava Cake quality standards Dry matter 47-50% Starch Min 92% (dry matter basis) Fibers 2.5-5% (depending on enzyme addition) Ash <0.6% Protein <0.5% HCN <2 ppm ph 3.8 4.0 Starch granule Excellent integrity for modification process One AMPU creates a market for 4500 smallholder farmers. Shelf life Storage Density Load >6 months Shade, ventilated, ambient temperature 1m3 equals 1,000 kg 33 ton in standard 40ft container *A single AMPU can supply sufficient starch adjunct for over 1 million hl beer per annum

Types of flour made from cassava Four types of cassava flour can be distinguished: 1. High Quality Cassava Flour(HQCF), obtained by industrial wet processing 2. High Quality Cassava Flour(HQCF), obtained by Small Medium Enterprises (SME) wet processing. HQCF Washing and Peeling Grating Pressing Drying and Cooling 3. High Quality Cassava Flour(HQCF), obtained by cottage industry manual wet processing. Milling Sifting 4. Cassava flour obtained by grinding of dried cassava chips Low quality, high in cyanide content, unhygienic Quality.
The art of making cassava flour High Quality Cassava Flour, its quality is determined by: 1. The Rasper (to rasp the roots into a mash); the more powerful the rasper the more released starch and the lower the cyanide content. 2. The Dryer; the quicker the drying and cooling down process the less moulds and microorganisms in the end-product 3. Hygiene and water quality.

Elimination of cyanide: a Prerequisite Cassava roots contain cyanogenic glucosides which breakdown to form hydrocyanic acid (HCN), a toxic compound. Processing is necessary to reduce the HCN potential. Traditional processing methods ineffective to reduce HCN potential to safe levels. To reduce cyanide levels you need to mechanical break down the cell walls with industrial raspers. Insufficiently processed cassava roots cause high levels of cyanide causing neurological disorders.
New developments 1. DADTCO s R&D team In collaboration with RIKILT, University of Wageningen and the Mondlane University Maputo Mz, has validated the fluctuating and high presence of Linamarin, a cyanogenic component present in cassava. On the basis of this validation the team has developed and patented an enzyme to produce 100% cyanide free cassava products (the research was financed by the Kutemann fund). 2. DADTCO s technology department has developed an ASPU (Autonomous Starch Processing Unit). The ASPU is built in a 20ft container and is designed to remove 70% of the fibres in the cassava slurry. The Starch Cake produced by a combination of AMPU and ASPU is: Cyanide free Contains very few fibres (can be compared to native starch in its behaviour) and contains 20% less water than the original Cassava Cake Is odourless and white in colour *DADTCO excited about development new technologies ASPU and Cyanide free cassava products
