[Problem] The present invention seeks to provide a composition for plants that is highly safe and that contributes to early harvesting, increasing yield, and increasing added value of crops. Specifically, the present invention provides a yeast extract that, by addition to a foliar surface spray or to soil or water, provides an effect of promoting growth, an effect of root lengthening, an effect of improved taste, and an effect of increased amino acid content of a plant. A substance obtained from yeast that is edible and considered to be safe is preferred as the yeast extract. [Means for Solving the Problem] A yeast extract having a peptide content of 5 wt % or more and an RNA content of 5 wt % or more is sprayed onto or provided as fertilizer to a plant. The yeast extract is preferably derived from Candida utilis, which is edible and considered to be safe.

The invention relates to a method for the fractioned separation of valuable substances from aqueous many-component mixtures such as aqueous wastes, sludges and sewage sludge under supercritical conditions. The invention also comprises valuable substance fractions that are enriched after the method according to the invention, more particularly phosphorous-containing and phosphorous- and ammonium-containing compounds such as fertilisers and synthesis gas as an energy source and as a valuable substance for the chemicals industry. The invention comprises devices for carrying out the methods. With the method and devices according to the invention, valuable substances can be completely recovered from wastes, sludges and sewage sludge and given a new use. The methods and devices are particularly suitable for recovering phosphorous and ammonium in the form of plant-available fertiliser, for recovering metals and heavy metals, for producing synthesis gas and for obtaining hydrogen from synthesis gas, i.e. for mobility.

A renewable energy microgeneration apparatus is disclosed that includes a mixing tank that mixes waste with a liquid, a buffer tank that receives and pre-warms the mixed waste, a pasteurization tank that pasteurizes on the pre-warmed mixed waste, a digestion tank that performs anaerobic digestion on the pasteurized waste, a de-watering device that separates liquid digestate and removes salt from the liquid, sensors that measure salinity and biogas quality, and a controller. The controller causes the transfer of digestate from the digestion tank to the pasteurization tank to the dewatering device, causes the de-watering device to separate the liquid and remove the salt from the liquid, monitors the salinity of the liquid and the quality of biogas using the sensors, and causes the mixing of the liquid with the waste and adjusts the feed rate of the waste to reduce the salinity of the waste and increase methane production.

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.

A rural bulk organic waste pollutant source comprehensive treatment system including a solid high-temperature aerobic fermentation reactor, a liquid high-temperature aerobic fermentation reactor and a multifunctional boiler is provided. A rural bulk organic waste pollutant source comprehensive treatment method. For excretion waste of a livestock farm adopting the technology of manure cleaning by urine submerging, a solid-liquid separation is firstly performed thereto, wherein solid is conveyed to the solid high-temperature aerobic fermentation reactor and fermented to produce solid organic fertilizers, and liquid is conveyed to the liquid high-temperature aerobic fermentation reactor and fermented to produce liquid organic fertilizers. For dry collection manure of a livestock and poultry farm, carbon-containing auxiliary materials, residues left after dead animals and household waste being incinerated by the multifunctional boiler, and ash generated by straw burning are added thereto, and then the mixture is conveyed to the solid high-temperature aerobic fermentation reactor and fermented to produce solid organic fertilizers. Exhaust fume and hot water produced by the multifunctional boiler pass through the solid high-temperature aerobic fermentation reactor and the liquid high-temperature aerobic fermentation reactor to heat the reactors and keep the reactors warm.
