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 to obtain Brassica seed oil, and feedstock comprising the Brassica seed oil is converted in a converting step, whereby renewable fuel or renewable fuel components are obtained. 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.
Claims26
A method for producing renewable fuels and renewable fuel components, where 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,
- in a first farming season, the doped Brassica seeds are planted in soil and a Brassica seed crop is harvested,
- in a farming season preceding or succeeding the first farming season, at least one plant selected from Brassica species, grain species or forage species is grown in the soil,
- the Brassica crop, grain crop or forage crop obtained in the farming season preceding or succeeding the first farming season is harvested, and at least part of plant biomass is left in and/or on the soil,
- 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, where 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,
- in a first farming season, the doped Brassica seeds are planted in 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, where 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,
- in a first farming season, the doped Brassica seeds are planted in 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.
