\n\t\t\t\t\t\t\t\t\tPreviously, silphium was used in its entirety to generate energy. Now, by focusing on cascading use, we also enable the fibers to be used as a raw material. Prior to bioenergy production, the fibers are separated using a biothermal procedure and are processed into a new, locally grown and sustainable raw material. And with zero chemicals. Just a small amount of water and energy are used. The remaining parts of the plant are fed into the biogas plant as a fermentation substrate.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The finished product features a good strength value thanks to the binding properties of the fibers and their high volume.

The Fraunhofer Institute for Environmental, Safety and Energy Technology (UMSICHT) examined the potential environmental impact of silphium-based paper and fibers and compared this with virgin fiber-based conventional pulp and packaging paper produced in Europe (data source: ecoinvent). The environmental impact of silphie fiber production is lower than that of cellulose fiber production, particularly in terms of energy and water use. The environmental impact of silphie fibers is far less than that of pulp. Silphie paper also features a host of environmental benefits that set it apart from pulp-based board: less fresh-water eutrophication, ozone depletion and smog buildup, more environmentally friendly use of mineral and metal resources, and an improvement in land use thanks to the silphium.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The use of silphie fibers as a substitute to cellulose is sensible from an ecological perspective. Based on our LCA (Life Cycle Assessment) carried out in 2021, there are advantages in 10 out of 13 impact categories. The only disadvantages are in the impact categories of eutrophication (marine and terrestrial) and acidification. These disadvantages are due to the fact that the silphium is an energy plant and is compared to wood. Would you like to take a closer look at the LCA? <\/strong><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

This supports rural areas, increasing regional value creation thanks to innovative bioeconomic solutions and safeguarding and creating jobs. By giving value to what was previously a by-product of biomass creation and processing and turning it into a raw material, we are simultaneously generating a new source of income for biogas plant operators. This boosts the profitability of biogas plants and secures their continued existence and the supply of renewables even after funding under the German Renewable Energy Sources Act (EEG) expires.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
