Abstract
The present invention relates to production of renewable fuels and fuel components from plant oil originating from at least one Brassica species, where said Brassica species, doped with at least one nitrogen-fixing bacteria is cultivated, in a rotating manner by alternating with at least one nitrogen-fixing plant species, plant oil is obtained from the Brassica species, and converted to renewable fuel or renewable fuel components. The invention also relates to a method for reducing nitrate release in renewable fuel production. Further, the invention relates to a method for reducing greenhouse gases in renewable fuel production.
Claims24
A method for producing renewable fuels and renewable fuel components, wherein the method comprises the steps, where
- seeds of at least one plant selected from Brassica species are doped with a doping composition comprising at least one nitrogen-fixing bacteria to obtain doped Brassica seeds,
- at least one nitrogen-fixing plant is grown in a soil in a first farming season, harvested and at least part of plant biomass is left in and/or on the soil,
- in a second farming season following the first farming season, the doped Brassica seeds are planted in the soil and a Brassica seed crop is harvested,
- the Brassica seed crop is treated to obtain Brassica seed oil and meal, and
- feedstock comprising the Brassica seed oil is converted in a converting step, whereby renewable fuel or renewable fuel components are obtained.
A method for reducing nitrate release in renewable fuel production, wherein the method comprises the steps, where,
- seeds of at least one plant selected from Brassica species are doped with a doping composition comprising at least one nitrogen-fixing bacteria to obtain doped seeds,
- at least one nitrogen-fixing plant is grown in a soil in a first farming season, harvested and at least part of plant biomass is left in and/or on the soil,
- in a second farming season following the first farming season, the doped seeds are planted in the soil and a Brassica seed crop is harvested,
- the Brassica seed crop is treated to obtain Brassica seed oil and meal, and
- feedstock comprising the Brassica seed oil is converted in a converting step whereby renewable fuel or renewable fuel components are obtained.
A method for reducing greenhouse gases (GHG) in renewable fuel production, wherein the method comprises the steps, where,
- seeds of at least one plant selected from Brassica species are doped with a doping composition comprising at least one nitrogen-fixing bacteria to obtain doped seeds,
- at least one nitrogen-fixing plant is grown in a soil in a first farming season, harvested and at least part of plant biomass is left in and/or on the soil,
- in a second farming season following the first farming season, the doped seeds are planted in the soil and a Brassica seed crop is harvested,
- the Brassica seed crop is treated to obtain Brassica seed oil and meal, and
- feedstock comprising the Brassica seed oil is converted in a converting step whereby renewable fuel or renewable fuel components are obtained.
