NOVELTY - A controllable process for composting waste material, includes placing the waste material into an automatically controllable composting environment (14); subjecting the waste material to a composting process; and periodically measuring the value of parameter(s) of composting environment, the parameters being temperature, pressure, moisture content, or gas composition.    USE - The process is for composting waste material (claimed), e.g. liquid waste, such as soft drinks, which are rich in materials like phosphorus and sugar. It is used for the remediation of hazardous waste, e.g. oily sludge, tank bottoms, and hydrocarbon-contaminated soils.    ADVANTAGE - The process is effective and economical. The optimization of composting conditions provides a homogeneous environment for naturally occurring microorganisms, to convert solid waste into organic compost. The prolonged heating of the waste material concurrently pasteurizes the compost, and ensures that the compost is free of pathogens and weeds. The composting process accelerates natural aerobic composting of waste material by up to a factor of five. The process can accordingly reduce a normally five week thermophilic stage of a composting process into approximately one week. Due to the aerobic conditions maintained within the container, the odor level is minimized due to production of oxidized gases, such as H20 and carbon dioxide (C02), instead of anaerobic gases such as methane, ammonia, and hydrogen sulfide. The process is ideally suited to recycling of waste in confined areas, and in close proximity to sensitive receptors.    DETAILED DESCRIPTION - A controllable process for composting waste material, includes placing the waste material into an automatically controllable composting environment; subjecting the waste material to a composting process; periodically measuring the value of parameter(s) of composting environment, the parameters being temperature, pressure, moisture content, or gas composition; comparing each measured value with a pre-determined setpoint or setpoint range; and automatically adjusting each parameter, such that the measured value of parameter(s) agrees with the setpoint or setpoint range.    An INDEPENDENT CLAIM is also included for a composting device (10) for carrying out controlled composting of waste material, including a closeable chamber for receiving the waste material, and forming a controllable compositing environment; sensor(s) for measuring the value of parameter(s) of the composting environment, the parameters being temperature, pressure, moisture content, or gas composition; mechanism for comparing each measured value with a predetermined setpoint value or setpoint range; and adjustment mechanism for automatically adjusting each parameter, such that the measured value of parameter(s) agree with the setpoint value or setpoint range.
