Retrofit box systems to maximize operational capacity of inaccessible floors are described. The retrofit box system includes a gate complex that provides fluid communication between an inaccessible floor and a box, and a box to deliver a cleaner to the inaccessible floor and adapted for equalizing pressure when the inaccessible floor is under water while minimizing waste seepage from the retrofit box system. The retrofit box system further includes a power system and a control system to deliver the cleaner to the inaccessible floor and remove waste from the inaccessible floor and the box.

An extraction apparatus for a fermentation medium comprises an extraction chamber configured to receive a fermentation medium and comprising a lower portion and an upper portion above the lower portion, as well as a feed device configured to feed at least one gas and one liquid into the lower portion of the extraction chamber, as well as a discharge opening arranged in the upper portion of the extraction chamber and configured to drain a washout liquid, loaded with microorganisms, from the extraction chamber.

The present disclosure provides non-intergeneric remodeled microbes that are able to fix atmospheric nitrogen and deliver such to plants in a targeted, efficient, and environmentally sustainable manner. The utilization of the taught microbial products will enable farmers to realize more productive and predictable crop yields without the nutrient degradation, leaching, or toxic runoff associated with traditional synthetically derived nitrogen fertilizer, by mitigating or eliminating the need for exogenous nitrogen-containing fertilizers. The remodeled microbes have unique colonization and nitrogen fixation abilities, which enable the microbes to deliver nitrogen to a cereal plant in a spatially targeted (e.g. rhizospheric) and temporally targeted (e.g. during advantageous stages of plants life cycle) manner. The microbes are able to replace the standard agricultural practice of sidedressing and enable a more environmentally sustainable form of farming. The present disclosure also provides methods of using non-intergeneric remodeled microbes, for example, to fix atmospheric nitrogen by reducing or eliminating the need for exogenous nitrogen-containing fertilizers, to increase yield, and to reduce infield variability in the yield.

The present invention relates to organic nitrogen fertilizers and methods for producing organic nitrogen fertilizers, including retrieving high concentration organic ammonia from discarded organic material.

The invention relates to a plant for treating a mixture of waste products from a domestic waste collection, comprising a unit for treating a mixture (2B) of materials obtained from the mixture of waste, a substantial portion of the mass of the mixture of materials being formed by biodegradable materials, the treatment unit comprising a trommel screen (3) which is provided with a wall (4) for separating the mixture (2B) of materials into a first fraction (5) passing over the wall (4) and a second residual fraction, two densimetric tables, and a ballistic separation means (8) which is positioned between the trommel screen (3) and the densimetric tables in order to collect the first fraction (5) of materials and to supply the densimetric tables with a first sub-fraction and second sub-fraction (9, 10) of materials, respectively, the first subfraction (9) being formed by materials which have a density lower than that of the materials forming the second sub-fraction (10).

Waste treatment methods and plants.

A compost monitoring device for use in monitoring properties of a body of compost, the compost monitoring device being configured to be positioned proximate to the body of compost in use, and including: a sensor array including sensors for sensing properties of gas proximate to the body of compost, the sensors including a temperature sensor for sensing a temperature of the gas, a humidity sensor for sensing a relative humidity of the gas, and a gas sensor for detecting a level of a gas compound emitted from the compost within the gas; a wireless transceiver for wirelessly communicating with another device located remotely from the body of compost; and a controller configured to obtain sensor data from the sensors; generate monitoring data using at least some of the sensor data, and cause the monitoring data to be transmitted to the other device using the wireless transceiver.

The present invention relates to organic nitrogen fertilizers and methods for producing organic nitrogen fertilizers, including retrieving high concentration organic ammonia from discarded organic material.

A method for the biological treatment of organic waste containing impurities consisting of non-biodegradable materials, including: • a first step of wet mechanical separation of the non-biodegradable materials present in the abovementioned organic waste in order to obtain a purified organic fraction, • a second step of dehydrating the purified organic fraction in order to obtain a dehydrated purified organic fraction and an effluent, • a third step of dry anaerobic biological treatment of the dehydrated organic fraction in order to obtain organic residues.

This disclosure provides a composting system and method. The system comprises: (a) a container configured to contain a composition and comprising (i) insulated walls, (ii) an air intake and (iii) a vent; and (b) a composition contained in the container. The composition comprises aerobic microorganisms, a carbon source and a nutrient source sufficient to support growth of the aerobic microorganisms. The container is sufficiently insulated so that heat generated by aerobic respiration is sufficiently retained in the container to maintain a heat gradient in the container. The container is dimensioned to generate a stack effect that moves air into the air intake, through the composition and out the vent. The moving air provides oxygen to support growth of aerobic microorganisms, making the stack effect self-sustaining as long as a carbon source and nutrients last. The insulation can maintain temperatures in the composting cell sufficient to kill pathogenic microorganisms.

The present invention relates to a microorganism mixture comprising one or more microorganisms selected from the Bacillus, Paenibacillus, lactobacillus, Pseudomonas, Trichoderma, aspergillus, and Saccharomyces genera, and which is useful in treating of solid organic waste. The present invention also relates to a composition comprising said microorganism mixture, a process for preparing said composition, a method for treating solid organic waste, and the use of the microorganism mixture or the composition of the invention in treating solid organic waste.
