Geography Inhabitants Industry Cities Rural areas Infra structure for

transportation Infra structure for

providing energy

Wine All surface is more than 56000 ha

3-7% Stems

Biohydrogen production by thermochemical conversion

Sugar beet

Two major factories in Castilla y León

Ebro and Acor 2.8 million tons per year Organic side product

called molasses Potential biomass for

ethanol fermentation due to high sucrose content

Breweries Mahou San Miguel

21,43 kg per liter beer in the Year 2005

70,45% organic waste (bagasse)

Used oil waste-oil collection system and management network in

Burgos and Avila used-oil collected from restaurants and households, also

from factories, schools etc. green spots and containers provided by the waste

management company problems: lack of budget of the local authorities, refusal of

restaurants and factories to keep the containers in their

establishment and the lack of implication of the citizens

Potential for biodiesel 1st generation biodiesel:

- Sunflower, cultivated in CyL Rapeseed - Food vs Energy: ethical issue

2nd generation biodiesel:- used vegetable oil collected from restaurants and

households of the region

Castilla y Leon responsible for 15% of Spain´s total energy production (5 Mtoe/year)

Current energy requirement: 7Mtoe/year

Potential for hydrogen wine industries could serve valuable biomass for

bioenergy production a total of 56337ha of land devoted to the vineyards the de-stemming process of the winemaking technology

generates from 3 to 7 % of stem depending on the grape type

The stems are lignocellulosic materials, and could serve as potential biomass in the thermo-chemical conversion (gasification and pyrolysis) for hydrogen production
