Comparing biobased products from oil crops versus sugar crops with regard to non-renewable energy use, GHG emissions and land use

Non-renewable energy use, greenhouse gas emissions and land use of two biobased products and biofuel from oil crops is investigated and compared with products from sugar crops. In a bio-based economy chemicals, materials and energy carriers will be produced from biomass. Next to side streams, also vegetable oils and sugars are expected to become important resources for these products. Application of these resources calls for effective resource use, with minimal environmental impacts. In this paper we study a number of available options and their trade-offs. Use of vegetable oils in a chemical and a resin results in a higher reduction of non- renewable energy use and greenhouse gas emissions than their use as biodiesel. Furthermore, similar savings in environmental impact per unit of land can be reached by products from either oil or sugar crops as transportation fuel, but the sugar crops, applied in chemicals or bioplastics outcompete the oil crops.
