Abstract: A bioreactor including one or more features that improve bioreactor liquid infiltration and gas recovery including a porous material layer having a layer of first porous material including a trench, a second porous material located in the trench and extending beyond the top surface of the layer of first porous material and perforated gas recovery piping located in the second porous material.

Abstract: An in-situ dry anaerobic composter containing 40% to 75% by weight solids and located in a section of ground including a pit having side walls and a bottom, an essentially impervious liner located in the pit such that the liner abuts the pit side walls and bottom to form a lined pit, a compostable material located in the lined pit and a gas management system for extracting a gaseous anaerobic decomposition product from the compostable material as well as methods for operating the anaerobic composter.

Abstract: Methods of remediating construction and demolition waste by collecting sulfur containing construction and demolition waste materials, adding a sulfur stabilizing agent to the construction and waste materials, admixing the sulfur containing construction and demolition waste materials and the sulfur stabilizing agent to form a sulfur stabilized construction and demolition waste material.

Abstract: A bioreactor including one or more features that improve bioreactor liquid infiltration and gas recovery and having a central core including liquid infiltration piping, a porous gas recovery material including at least one gas collection pipe, and a berm separating the central core from the porous gas recovery material.

Abstract: A method and apparatus for sequentially nitrifying ammonia in landfill leachate ex situ and then returning the nitrified landfill leachate to the landfill where the leachate is denitrified.

Abstract: Landfills including multiple lifts having horizontal piping layers and methods for their use to accelerate anaerobic and/or aerobic degradation of municipal solid waste to increase landfill capacity.

Abstract: A process for converting hazard explosives that are contaminating soil into reduced derivatives and thereafter converting the reduced derivatives into humic compounds by admixing the explosives contaminated soil with a natural microorganism source and with an oxidizable carbon source and subjecting the mixture to anaerobic conditions to produce an anaerobic bioremediation product containing reduced concentrations of explosives contaminants and thereafter combining the anaerobic bioremediation product with a compostable material and subjecting the second mixture to aerobic conditions to give an aerobic bioremediation product that is essentially free of explosives contaminants and their reduced derivatives.

Abstract: A method and an apparatus for continuously treating an organic compound contaminated soil heap with an ozone containing gas using a closed loop gas recycle system.

Abstract: A system for treating soil contaminated by petroleum hydrocarbons which comprises applying a suitable bacterial culture capable of degrading petroleum hydrocarbons in a dry form to the bottom of an excavated cavity, applying gravel to a suitable depth over said dry cultures, providing a system of distribution piping capable of supplying nutrients directly to said cultures, and also an air flow through the area containing said cultures, and placing the appropriate tank in place within said cavity and covering with gravel and dirt.The system is activated by providing said cultures with a source of nutrients through said piping followed by flowing air through the piping to facilitate metabolization of the hydrocarbons contained in the soil.

Abstract: A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises a porous outer covering member which forms an enclosed package with a source of bacterial cultures contained within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.

Abstract: A new hybrid tea rose plant is provided as developed from a seedling in a direct effort to breed a new variety. The new rose plant resulted from the crossing of parent varieties of Chablis and Pristine and features a vigorous growing habit, an ability to yield abundant blooms on an almost continuous basis, and distinctive coloration changing from beige at the base of petal to a light pink on both sides of the petal. High resistance to blackspot is also exhibited.
