A multi-autoclave lateral conversion module includes a central mixing process pipe having first and second terminal ends, a heating unit providing heated air at the first terminal end of the central mixing process pipe, two or more gas injection units connected to opposing sides of the central mixing process pipe at a first addition point located between the first and the second terminal ends, and each gas injection unit receiving the process discharge gas from an autoclave unit. The process discharge gas is transmitted from an autoclave unit through the gas injection unit into the central mixing process pipe where it mixes with the process discharge gas from the other autoclave unit, and then the mixed process gases are converted. Process units other than autoclaves can also utilize the module and method provided.

The embodiments described relate to an expeditionary solid waste disposal system configured to improve logistics and enable it to be readily deployed. The two-stage gasification/oxidation process takes place in a dual chambered device that resembles and functions as a shipping container. Incinerators or other waste conversion devices are commonly containerized by loading the equipment into a standard or modified shipping container. This apparatus is designed as a waste conversion unit that integrates all of the necessary features required to be an ISO-certified shipping container within its structural design such that the waste conversion system and shipping container are one and the same. With correct set-up by 2 persons aided by forklift the system can be configured and operational in a matter of hours.

A bale boiler incinerates bales of material, and particularly bales made from waste, garbage and other refuse, in order to provide heat for a steam turbine generator, and includes a conveyor for transporting bales of waste material through a three-stage boiler. The boiler is preferably divided into three stages: 1) the warming stage, 2) the main incineration stage, and 3) the supplemental incineration stage. In the warming stage, the bale is warmed and dried. In the main incineration stage, the bale is burned to create heat that is then used to power a steam turbine electrical generator or the like. In the third, supplemental incineration stage, the remnants of the bale burn down to ash, and the remaining ash and non-combustible waste are then transported out of the boiler by the conveyor and dumped into a receptacle or container for transport and disposal.

Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

A gasification apparatus has a primary chamber with a floor comprising a hearth and feedstock augers, for gasification of feedstock. There is a mixing chamber for receiving through an opening synthetic gases from the primary chamber and comprising an air inlet fan for adding oxygen for ignition. There is also a secondary chamber linked with the mixing chamber to deliver heat from combustion of gases from the mixing chamber to the hearth. An outlet valve delivers gases from the secondary chamber through a heat exchanger and to an induce draft fan. A controller dynamically controls flow of gases in the chambers according to sensed pressures and temperatures in said chambers.

The present invention provides a method and a system for processing of waste by anaerobic digestion, said method comprising pre-treatment of a first biological waste stream by thermal hydrolysis and processing of a solid fraction by pyrolysis prior to anaerobic digestion.

The present invention allows for efficient utilization of the energy available in biological waste sources. The method provides an energy efficient method for processing of biological waste having a high degree of recovery of the energy stored in the waste material, wherein the flow of material may be dynamically adjusted to e.g. achieve end products in preferred ratios.

The description describes the integration of a gas fermentation process with a gasification process whereby effluent from the gas fermentation process is recycled to the gasification process. The one or more effluents which can be recycled include a stream comprising microbial biomass, a product stream comprising at least a portion of the at least one fermentation product, a by-product stream comprising fusel oil, and a waste water stream comprising microbial biomass. The stream comprising biomass can be dried before it is passed to the gasification zone. At least a portion of the waste water stream can be passed to the gasification process where one use is to replace at least a portion of the process water. The waste water stream can be further processed to produce a clarified water stream and a biogas stream comprising methane either or both of which can be passed to the gasification process.
