Claim Text:
1. A method for producing bio-oil from an organic matter feedstock, the method comprising: producing a slurry comprising between about 20% and about 40% by weight of organic matter feedstock, water and between about 20% and about 60% by weight of oil; treating the slurry in a reactor apparatus at a temperature of between about 200° C. and about 450° C. and a pressure of between about 100 bar and about 350 bar; and cooling the slurry and releasing said pressure thereby providing the bio-oil, and using a recycled portion of the bio-oil to treat additional organic matter feedstock by the method, in which an additional slurry comprising between about 20% and about 40% by weight of the additional organic matter feedstock, water, and between about 20% and about 60% by weight of the recycled portion of the bio-oil is treated in a reactor apparatus at a temperature of between about 200° C. and about 450° C. and a pressure of between about 100 bar and about 350 bar, then cooled and depressurised to thereby provide additional bio-oil.
