The present invention concerns an anaerobic digestion of animal manures, energy crops and similar organic substrates. The process is capable of refining nutrients comprised in the digested biomass to fertilizers of commercial quality. The invention also provides a method for processing animal carcasses or fractions thereof including meat and bone meal etc., with the objective of providing an alternative means for processing the organic waste material of animal origin while at the same time facilitating the production of fertilizers. The risk of spreading BSE prions or any other prions to animals or humans is thus substantially reduced if not eliminated. The biogas and slurry separation system according to the present ivnention is preferably integrated with the operations of animal husbandries into a total concept in which the internal and external performances of animal husbandries are optimised. The internal performances concern quality aspects related to the management of the animalhouses and include industrial hygiene, animal welfare, gaseous and dust emissions and food safety. The external performances concern mainly energy production and emissions to the environment of nutrients and greenhouse gases and the sale of high quality food product.

A process is provided using non-food or limited-feed agricultural residue and energy crops for energy production, such as ethanol or electricity generation. The agricultural plant material is harvested and baled. The bales are transported to the processing site for storage or immediate processing. The bale strings are first removed, and then the broken bales are shredded. The shredded plant material is then ground to a small size. The ground material is then pelletized to produce densified pellets of the agricultural plant material. The pellets are cooled and then stored or transported to an end user.

The present invention is directed to improved systems and methods for reducing costs and increasing yields of cellulosic ethanol. In particular, the present invention provides plants genetically transformed for increased biomass, expression of lignocellulolytic enzymes, and simplification of harvesting and downstream processing. Also provided are methods for using these transgenic plants in the production of clean, marketable feedstocks for production of renewable fuels and chemicals and in other applications including phytoremediation.

A process for converting lignocellulosic materials which are field residues such as cotton stalks and corn stover, process residues such as sugarcane bagasse and sweet sorghum bagasse, woody parts of energy crops such as switchgrass and miscanthus, forest residues or byproducts of the wood processing industries such as sawdust from sawmills to a liquid biofuel by a series of processing steps wherein the feed materials are hydrolysed in three stages and withdrawn as three product streams each consisting of solubilized fragments of one of the three major components of the feed materials and a set of concurrently operating processing steps wherein each of the three product streams is transformed through chemical or biochemical processes into products, such as pure lignin and ethanol, that have a high calorific value and process wherein these products with high calorific value are combined to form a liquid biofuel.

A novel Biomass Combustion Unit apparatus purposefully designed to be uniquely fueled with Non-To-Minimally Fractionalized Biomass for the intentional production of heat for conversion to a multiplicity of useful energy forms. More particularly, said apparatus provides useful heat for: (i) Power Generation, (ii) Heating Applications, (iii) Cogeneration or Combined Heat and Power (CHP), (iv) Trigeneration or Combined Cooling, Heat, and Power (CCHP), (v) Mechanical Energy and (vi) Facilitating the production of Biofuels. Additionally, methods and systems are presented wherein the abovementioned forms of energy deploy organic and inorganic working fluids, in both Subcritical and Supercritical Power Generation Cycles, via Organic Rankine Cycle and a modified Rankine Cycles, respectively. Further, Woody Biomass Energy Crops and Biofuel components are presented as well.
