The industry is interested in establishing a biorefinery sector in Denmark that can replace oil-based products with biofriendly materials, chemicals, energy and fuel. But this requires a larger biomass production than we are currently achieving. Scientists from University of Copenhagen and Aarhus University have published an extensive report that shows how we can increase the production of biomass by more than 200% in an environmentally friendly way.
The report called "The ten-million-tonne plan" shows how we can increase the Danish production of biomass from agriculture and forestry by 10 million tonnes per year without affecting the current production of feed and food.
The plan also shows how we can substantially reduce the environmental impact compared with current levels.
"It sounds too good to be true, but it is quite realistic. By concentrating on a number of areas we can in practice double plant production and improve the utilisation of existing resources so there is enough both for food and feed production and for an additional 10 million tonnes of biomass in 2020," says Morten Gylling, senior advisor at the Faculty of Science, University of Copenhagen.
The report contains a number of specific subelements that combined provide a solution for how we can use sustainable biology and technology to get an additional 10 million tonnes of biomass a year by 2020 without incorporating more agricultural land.
"One of the options is to double crop yield per hectare in selected areas. This can be done by converting to cropping systems with improved perennial crops and break crops to extend the growing season and thus more fully exploit the solar radiation. This will be sufficient to meet the requirements for both feed and food production and for the biomass production for a number of biofriendly products," explains Uffe Jrgensen, senior scientist at Aarhus University.
