  21. 21. Recovery 50 %:1 kg Potatoes = 0.5 kg French Fries Raw material:100 ha x 15 T/ha = 1.500 T processing potatoes 750 t French fries for the market in the 1st year Vegetable oil content 5-7 % (crisps: 30%) Investment processing line: >1.3 M USD (modules) 100 ha of production requires 250 t of seed Organize seed, contracts storage Waste (water) Farmers’skills Some business deliberations
  22. 22. Frozen potato products and raw material for crisps have become global commodities To be competitive farm gate price less than 150 USD per ton; availabilit year-round Yields should be at least 25 t/ha in e.g. Rwanda and Ethiopia Meeting specs: colour, L/W, DMC, Reducing sugars (McFry?) Ethiopia or Rwanda ? Consider yields, sunshine, irrigation, storage and size of the market (capital) Competitiveness of raw material in Africa
