The present invention relates to an anaerobic column reactor for biodegradation of wastes. Particularly the present invention relates to a process for conversion of biodegradable wastes to biogas and compost. More particularly, the present invention relates to an anaerobic reactor with unique arrangement of expanded and constricted portions alternatively placed vertically over each other which enhances the mixing pattern and thereby the mass transfer rates while controlling the biomass washout by regulating the upflow liquid velocity.

Recycled paper pulp is processed to form a rigid paint tray base. The paint tray base is then laminated with a film, which may be fully or partially recyclable and/or biodegradable. The film prevents saturation of the pulp from the paint's moisture, which would damage the integrity of the pulp. Once the painting is completed, the film may be separated from the pulp base. The pulp base may then be discarded with wastepaper or used for compost. The film may be recycled or disposed of with other non-biodegradable waste.

The invention relates to polyurethane foam material based on wheat straw as raw material, and the preparation method. The wheat straw as raw material is treated through liquefaction to obtain liquefied polyol which is then polymerized with di-isocyanate to form degraded polyurethane foam material.

Meanwhile, the processor is also provided with a flower and grass culture chamber and can be used for processing waste gas generated during fermentation and also making a contribution to the improvement of environment quality. The equipment is simple to manufacture, convenient to use and capable of truly realizing reclamation, minimization and benefits of waste treatment.

The invention provides special antibacterial masterbatch for a biodegradable garbage bag. The antibacterial masterbatch is prepared from components in parts by mass as follows: 20-85 parts of PBAT (poly(butylene adipate-co-terephthalate), 0-30 parts of polylactic acid, 10-70 parts of papermaking waste and 0.5-15 parts of an assistant. The invention further provides a preparation method. PBAT, polylactic acid, the papermaking waste and the assistant are mixed uniformly and subjected to extrusion and granulation, and the special antibacterial masterbatch for the biodegradable garbage bag is obtained. With the adoption of the preparation method, a large amount of papermaking waste can be recycled effectively; the papermaking waste has certain antibacterial activity, so that the special antibacterial masterbatch modified with the papermaking waste for the biodegradable garbage bag also has certain antibacterial activity, decay and fermentation of organic matter in garbage can be inhibited,and peculiar smell emitted by garbage decay can be reduced.

A composting system and method incorporating a vertical insulated composting tower with one or more compartments. The base of each compartment being fitted with a plenum and grate through which air is self induced and output is regularly removed. The method of composting biodegradable waste material utilises a plug flow principle including inducing low air flow rates through a compost pile using column energy. The method utlises high temperature pyro/thermopylic micro-organism activity in the compost pile and retaining pile energy above levels by controlling the induced air flow. Evolved gas extraction is utilised in the compost pile and constant biofilm is maintained by combined cycle anaerobic/aerobic operation.

This method facilitates the cost effective treatment of liquid and solid waste in a landfill or composting facility. The ability to distribute the oxygen to the waste and remove the spent waste is the key to the process. The process can digest a megafill or treat massive green waste pile. Waste moisture content is increased, eliminating fires and removing a major constraining factor to degradation. Large quantities of liquid are oxygen-supplemented (therefore treated) and are added directly into the MSW or compost to maintain aerobic degradation. Oxygen is the limiting factor; water is the distribution method. Temperature increases with the availability of oxygen. The bacteria break down the solid and liquid waste. The material is available for cover or agricultural uses. Facility space is reused, odors are minimized, and environmental risk is minimized. Leachate is treated to the needs of the facility, which can be anywhere between total treatment and pretreatment.

An artificial hollow core boulder and method of fabrication. A plastic trash bag is loosely filled with newspaper, tied shut, and wrapped with a layer of chicken wire. The chicken wire wrapped bag is hand pressed into a boulder like shape and a hole is cut into the chicken wire at the bottom of the wrapped bag.
