A process for transforming a stream of MSW material into feedstock for an anaerobic digester and the resulting generation of biogas and other useful products includes the removal of one or more selected chlorine containing components and the retaining of substantially all paper components. At least 70% by mass of the incoming stream of MSW material is hydrolyzed and subsequently directed to the anaerobic digester.

A system for conducting high-temperature thermolysis of a waste mixture formed by sewage sludge and wood waste (e.g., creosote-impregnated wooden railway sleepers and utility poles) is proposed. The products of the high-temperature thermolysis may be used to produce thermal energy, electrical energy, carbon black, and liquid fractions which may be used profitably for various purposes.

A process of treatment of waste blend textiles comprising polyester fibers and cotton fibres depolymerizes polyester in a controlled environment to obtain treated textile comprising cotton staple fibers suitable to be recycled into cotton yarns.

The present disclosure refers to a method of electrochemical conversion of organic waste to organic acid and hydrogen, comprising the steps of: (i) subjecting organic waste to ball milling under alkaline or acidic conditions to obtain pre-treated organic waste; (ii) introducing the pre-treated organic waste to a first compartment of an electrochemical cell, wherein the electrochemical cell comprises: the first compartment containing a nickel-based anode, a second compartment containing a cathode, and an electrolyte; and (iii) applying an electrical potential between the anode and the cathode, thereby producing organic acid at the anode, and hydrogen at the cathode. The present disclosure also refers to an organic acid or hydrogen produced from the method disclosed herein.

Subject of the invention is a method for recycling a glass fiber product waste to obtain recycled glass fibers. By using the waste glass mat recycling method of the invention a complete separation of the glass fibers from the binder or any other bonded precipitations is achieved. The glass fibers regained by the method are undamaged glass fibers having preserved their original geometry and mechanical performance. Surprisingly the recycled glass fibers have a surface that is very smooth, plain and wave less. A further subject of the invention is glass fiber product comprising glass fibers and at least one binder is provided, wherein the glass fibers contain at least 2% by weight of recycled glass fibers and up to 98% by weight of new glass fibers.

A thermally solidified sound-absorbing nonwoven fabric having a fluid resistance of 150 Ns/m.sup.3 to 5000 Ns/m.sup.3, measured in accordance with DIN EN 29053, May 1993, and an area density of 150 g/m.sup.2 to 600 g/m.sup.2, including structural staple fibers having a mean titer of 0.9 dtex to 8.8 dtex, in a proportion of 50 wt.-% to 90 wt.-% in relation to an overall weight of the nonwoven fabric, and core-spun binding fibers in a proportion of 10 wt.-% to 50 wt.-% in relation to the overall weight of the nonwoven fabric. The structural staple fibers include a percentage of reprocessed structural staple fibers and the core-spun binding fibers include a percentage of reprocessed core-spun binding fibers.

Clean, safe, and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various waste sources into a Clean Fuel Gas, Char, and Biochar are provided. The process further converts the Clean Fuel Gas into both a purified hydrogen source for green ammonia production and natural gas. The methods process waste sources to effectively separate, neutralize and/or destroy halogens and other hazardous components to provide a Clean Fuel Gas, Char and/or Biochar, which can then further be processed to extract and purify hydrogen for green ammonia production from the Clean Fuel Gas and thereby provide natural gas. The Clean Fuel Gas is a natural and renewable natural gas as it is continually produced and further available for use to provide energy and new products.

Disclosed is a waste processing plant and method of processing waste biomass. The plant includes a waste receiving apparatus for receiving biomass waste and processing it into a liquid stream before passing it to, anaerobic hydrolysis tanks for hydrolysis, acidification and acetylation of the stream, before passing it to, a heat exchanger for raising the temperature of the stream to a pasteurization temperature, pasteurization tanks for holding the stream at the pasteurization temperature to ensure adequate pasteurization before passing it to, and anaerobic methanogenesis tanks for anaerobic digestion of a portion of the stream into biogas. Also included is a centrifugation apparatus to separate oil from the stream, wherein at least a portion of the stream which is downstream of the hydrolysis tank(s) and upstream of the methanogenesis tank(s), and which has a temperature of above 68 C., is centrifuged by the centrifugation apparatus to remove a portion of the oil.

The disclosure relates to the field of solid biofuels obtained by steam cracking. More particularly, the disclosure relates to a process for the treatment of lignocellulosic biomass by steam cracking in which the obtained powder is treated in order to separate the particles into two categories according to a threshold value, and each category is treated differently.

This disclosure generally relates to engineered recombinant bacterial cells producing enzymatic compositions for up-cycling plastics, biomass waste, or co-mixtures of plastics and biomass waste. The disclosure also relates to dual enzyme compositions produced by the recombinant bacterial cells for upcycling plastic materials and/or biomass waste, and methods for upcycling plastics, OHD-treated substrates and/or biomass waste.
