3 Most important challenge of mankind will be Feeding the world and Solving the energy problem Depletion of today s resources e. g. oil, gas, coal and phosphate AND Global warming because of greenhouse gas emissions The only long-term solution is the increased usage of renewable resources. ESOF,
4 Südzucker Group: Overview Globally operating European food group Segments: sugar, special products, fruit 18,600 employees 5.8 billion annual turnover Sugar production: 4.6 million tonnes Leader on the European sugar market Member of German MDAX ESOF,

8 Common sense Energy savings have highest priority Increased efficiency e. g. in industry is inevitable Exchange through renewables has to be brought forward ESOF,
9 Energy needs for different purposes We need energy for different purposes Heating and cooling Production Transportation Electricity (different purposes) However, we are used to have energy supply on demand. Not alle renewables are staple energies (solar, wind). ESOF,

11 In a country like Germany Today, 8.5 % of end energy usage is based on renewables of which two thirds are based on bio-mass. In future (2020), exp. share of end energy usage will be 18 % of which two thirds will be based on bio-mass. *) This means that due to the increasing share of renewables in total energy consumption an important additional bio-mass production will be needed. *) acc. to BMU ESOF,

31 Bio-energy from European crops (e. g. bio-ethanol) Uses only the fixed carbon All valuable parts of the bio-mass are further used in the traditional chain e. g. as Feed and/or Fertilizer The menure of feed usage following state of the art technology can be processed to Bio-gas (again consuming the fixed carbon) The residues incl. all NPK will be recycled as fertilizer. ESOF,
32 Breeding the crops More towards carbohydrate yield/ha Accepting a slight decrease in protein yield/ha and Accepting a decrease in oil yield/ha Could result - as proven for beets - in A strong increase in energy yield and In case of using these crops as e. g. raw material for bio-ethanol an excellent energy yield besides a balanced feed production and an optimized fertilizer recycling.

35 Meat production and GHG emissions More meat means more GHG emissions? Today s meat production in large regions of the world works with very extensive methods Grazing fodder high in fibres low in easily accessible energy No state of the art menure treatment The Commission has decided to reduce meat production in Europe and to import more meat from regions with extensive production. ESOF,

37 Meat production and GHG-emissions Extensive meat production causes intensive GHG-emissions esp. CH4 which is 25 times more GH efficient than CO 2 and N2O which is 298 times more GH efficient than CO 2 Exchange of extensive meat production with feed high in fibre by a more starch based feed incl. state of the art menure treatment with bio-gas production will result in reduced CH4 and N2O emissions A more industrial agro-crop feed production instead of pasture will help to reduce the negative emissions of meat production.

57 Conclusions (1) Worldwide, there is a lot of potential future arable land, however, due to possible liberation of bound CO 2 deforesting (esp. rain forest) has to be avoided and is not necessary. Huge yield increase in the past, however, esp. the last 10 % of the increase often has an unfavourable cost to income ratio. If breeding progress is focused on fixed carbon (for bio-energy) as successfully proven for beets, future success for cereals seems to be probable while retaining the feed/fertilizer value of the by-products and optimum energy yield. GHG emissions in meat production could be reduced using more industrially intensive methods by exchange of fibre rich fodder (grazing) through a more starchy one and state of the art menure treatment (incl. biogas production) and resources recycling as fertilizer. This combines optimized energy yield with lowest land use and optimized resources saving. ESOF,
58 Conclusions (2) Comparison of different bio-mass based energy uses shows Lowest CO 2 saving cost for wood burning producing heat and power (however availability??) followed by bio-ethanol used as fuel in low blends. Power production via bio-gas seems to be the most costly solution. Land use is not easy to judge All additional bio-mass production for bio-energy use is competing with the available area, however, the net effect incl. optimized bio-fuels by-products use as feed and fertilizer has to be integrated into the calculations. ESOF,
59 An optimized bio-mass production to Feed the world and Contribute best to the energy problem needs an industrial agrarian bio-mass supply with optimized meat production (incl. by-products use) and resources recycling using all available technologies from breeding over processing to consumption. ESOF,
