No, you don't drink the black liquor. Volvo invests in Chemrec AB for production of synthetic gases
Chemrec, which operates a plant in Piteå, Sweden, uses black liquor (a residual product from the pulp industry) to produce synthesis gas. While black liquor can be burned to recover chemicals and use the heat energy, Volvo says, gasifying the liquid is more efficient because it nets a number of by-products – including synthesis gas. And then, somehow, "With this synthesis gas it is possible to utilise known techniques to extract vehicle fuels such as bio-diesel, hydrogen gas, synthetic diesel and DME."
