Comparision of decentralised cold pressing to industrial extraction with solvent
decentralised cold pressing	industrial extraction with solvents
medium scale, co-operative or private enterprises	corporations that are mainly connected to multinational concerns
Located near to agricultural production	Located near to central traffic points
Directly or indirectly connected to the agricultural production(no middleman)	Normally separated from the agricultural production(with middleman)
Capacities<25t/d	capacities>500t/d
Production of cold pressed plant oil and press cake	Production of refined and half refined plant oil, extraction press cake
Higher feed value of the press cake (12-17% oil content)	Oil content of extraction press cake <1%
Low investment costs	High investment costs
Lowenergy consumption (80kWh/t seed)(on average 6 times lower than for industrial extraction)	High energy consumption(470kWh/t seed
No use of chemical solvents or thermal conditioning of the seed	Solvent extraction and thermal pre-conditioning
No waste water	Waste water from the refining(approx. 50l/l oil
Low logistical expenses and security requirements	High logistical expense and security requirements
Short local transportation distance (typically 50km), stimulation of local sconomy	Long, sometimes international transportation to and from central plants, high investment costs to ensure environmental protection
High flexibility (faster process adjustments to other kinds of oil seeds)
Addiyional creation of value in rural areas
