METHODS TO PRODUCE PRODUCTS FROM ANAEROBIC DIGESTION OF POULTRY LITTER
Some embodiments are directed to a process for forming products from animal waste (e.g., poultry litter). The products may include a controlled release fertilizer and renewable natural gas. The process may include providing a feedstock comprising greater than about 80 percent poultry waste and a moisture content of about 25 percent. The feedstock may be diluted to form a slurry having a moisture content of about 90%. The slurry may be mechanically refined to reduce the particle size distribution and the average particle size of the slurry. The slurry may be anaerobically digested to produce biogas and a digestate. The biogas may be converted to renewable natural gas, and the digestate may be converted to a controlled release fertilizer. Additionally, some embodiments are directed to methods of reducing nitrogen emission from soil amendments. Some embodiments are directed to reducing nitrogen emissions sufficient to produce emissions offset credits.
Recycling a Used Absorbent Hygiene Product or its Components Using Hydrothermal Treatment
Used AHP or its components is converted into low molecular weight hydrocarbons using HTT reactor. These low molecular weight hydrocarbons produce ethylene, propylene, and other chemicals when fed into a steam cracker, which can be used to produce recycled components of the AHP or a fully recycled AHP.

APPARATUS FOR RECYCLING OF LIGNOCELLULOSIC FIBRES FROM FIBREBOARDS
The invention related to an apparatus for recycling of lignocellulosic fibres from a fibreboard comprising compressed lignocellulosic fibres bonded together by a binding agent. The apparatus comprises a transport device arranged within a closed housing, wherein the housing is arranged for steaming pieces of the fibreboard at super-atmospheric pressure to decompress and release the lignocellulosic fibres by hydrating them, as well as hydrolysing the binding agent, and the transport device is arranged for transporting the fibreboard pieces, upon being steamed, from an inlet of the housing, at which the fibreboard pieces are fed to the housing, to an outlet of the housing, at which steamed portions comprising released lignocellulosic fibres exit the housing. Further, the apparatus comprises a steam generator in communication with the housing, whereby the fibreboard pieces may be steamed at super-atmospheric pressure in the housing to provide the steamed portions comprising released lignocellulosic fibres, an inlet pressure lock configured to receive the fibreboard pieces at atmospheric pressure and to deliver them to the housing, via the inlet, at super-atmospheric pressure, and an outlet pressure lock configured to receive steamed portions comprising released lignocellulosic fibres via the outlet and ejecting recycled lignocellulosic fibres during a sudden expansion of super-atmospheric pressure.
