Abstract

The present invention relates generally to the generation of bio-products from organic matter feedstocks. More specifically, the present invention relates to the use of pulping liquors in the hydrothermal/thermochemical conversion of lignocellulosic and/or fossilised organic feedstocks into biofuels (e.g. bio-oils) and/or chemical products (e.g. platform chemicals).
