A system reduces and/or prevents the risk of spontaneous ignition and/or explosion of an explosive atmosphere which uses a bag, sealable couplings, automated valves, an explosive gas detector operably disposed inside the bag and in communication with a processor which when the explosive gas detector detects gas levels of an explosive type gas and of a second predetermined molecular weight different than the first predetermined molecular weight and at level to present a risk, the processor causes actuation of the automatically controlled valve to open and release the inert gas into the bag which in turn drives the explosive gas out through one way check valve by means of the different molecular weights.

A domestic organic waste composter is provided. The composter can include an inlet for receiving organic waste; a grinder for grinding the organic waste; a tank surmounted by the grinder and arranged to contain the organic waste ground by the grinder; a mixer arranged in the tank and configured to mix the ground organic waste contained in the tank; an outlet arranged at the level of a bottom of the tank to recover a potting soil produced by composting the organic waste contained in the tank; and an aeration system configured to generate a circulation of air in the tank from the air inlet towards the air outlet via orifices. The aeration system can include an air inlet containing a fan; the orifices for circulating air in the tank; and an air outlet fluidly coupled to the orifices.

The proposed solution relates to a method and a device for composting organic material, e.g. a corpse, using a composting container. In this case, it can be provided that at least one of before and during storage of the composting container for a predetermined composting time in each case predetermined amounts of at least one of liquid and oxygen are filled into the composting container, and during the storage at least one rotation of the composting container takes place about an axis of rotation which is non-parallel to an effective direction of a weight force acting on the composting container, and the content of the composting container is held during storage, for a predetermined composting time, in a predetermined temperature range, via at least one heating element.

Various embodiments are described herein for an apparatus that implements one or methods for producing compost. The method may include receiving waste in a composting apparatus, the waste having a first moisture content; pre-treating the waste to produce pre-treated waste; storing the pre-treated waste into a storage chamber for a pretreatment time period to produce stored waste; and composting the stored waste in a compost chamber to produce a batch of output compost having a second moisture content, wherein the second moisture content is less than the first moisture content.

The present invention relates to an organic matter biodigester comprising a tank that has an organic matter inlet, a first connection arranged in an upper portion of the tank and a second connection arranged in the lower portion of the tank. Furthermore, said tank also has a biogas outlet and a lower surface configured to rest on a support surface. Furthermore, the lower portion of the tank is at a shorter distance from the support surface compared to the upper portion of the tank. Said organic matter biodigester also comprises a manual pump with a pump inlet connected in the second connection, and a pump outlet connected in the first connection of the tank. The pump is configured to recirculate the organic matter inside the tank from the second connection towards the first connection; and a porous layer arranged inside the tank.
