Benefits

• Production of Renewable Energy

• Alternative to fossil fuel

• Prevents leaching of nutrients

• Recycling of nutrients to croplands

• Potential for organic/ecological fertilizer

• Preserves the open landscape

• Increase in biodiversity

• Recreational value will increase

Conclusion: - ongoing learning

• Cheap carbon sources; identify feedstocks on location – regional.

- But it have to be cheap and sustaiable!

• Manure of any kind; including solid manure types

• Straw and lignocellulosic byproducts incl. bagasse (Brazil!)

• Grassland products from nature, extensive & intensiv farming

• Organic food waste and organic wasted byproducts

• Industrial organic waste streams and byproducts. Recycling

• Aquatic algaes macro/micro & byproducts (have to be developed

Thank you for your attention!

Biogas is growing world-wide to be a big & sustainable energy

player!!!☺- But we don’t have to time to do it wrong!
