Disclosed is a method for reducing methane emission from slurry produced in a livestock farm. The method comprising the steps of guiding unheated slurry from the livestock farm to a slurry heat exchanger, raising the temperature of the unheated slurry in the slurry heat exchanger to at least 65# Celsius, guiding the at least 65# Celsius hot slurry to an intermediate slurry tank, raising the temperature of the heated slurry to at least 75# Celsius in the intermediate slurry tank, guiding the at least 75# Celsius hot slurry through the slurry heat exchanger to exchange heat with the unheated slurry to raise the temperature of the unheated slurry to the at least 65# Celsius and to cool the at least 75# Celsius hot slurry to at least below 40# Celsius, and guiding the at least below 40# Celsius cold slurry to a slurry reservoir. Furthermore, a slurry treatment plant for reducing methane emission from slurry is disclosed.

An aerobic method for treating organic material, having the steps of loading a treatment unit with organic material; covering the organic material with a first membrane; aerobic treatment of the organic material by actively supplying air to the organic material and the supplied air flowing through said organic material; turning over the organic material using a turning-over device, wherein the organic material is homogenized and/or mixed; and continuing the supply of air according to step c). The turning-over device is moved along the direction of longitudinal extent of the treatment unit, turning over the organic material by a turning-over roller. The turning-over device has a membrane holding apparatus which holds the first membrane covering the organic material during the turning over, and a membrane laying apparatus, which lays a second membrane on the turned-over organic material.

There is disclosed a method of producing a soil remediant from liquid organic waste material in which the liquid organic waste material is concurrently pasteurised and digested by thermophilic aerobic digestion in the liquid phase in a single digester vessel. The organic waste material in the digester is maintained continuously at a temperature of at least 70° C. for at least an hour and the liquid organic waste material comprises at least 70% water and can be pumped. After a period of at least an hour a small amount of pasteurised organic waste material is removed and a corresponding amount of fresh organic waste material is added to the single digester vessel such that the temperature is maintained in a comfort zone of the thermophilic bacteria. In a preferred embodiment the thermophilic aerobic digestion is facilitated by micro-organisms including crenarchaeota. The liquid organic waste material can be combined with a microporous adsorbent. Also disclosed is a soil remediant comprising a microporous adsorbent and liquid organic waste material from the novel method. The microporous adsorbent may be a volcaniclastic sedimentary rock or diatomite or of vegetable origin such as biochar. The microporous adsorbent may be a powder or a granular material and may have particle sizes up to 2000 microns.

A process and apparatus is disclosed for utilizing African American hair removed from a person's scalp as a fertilizing agent with superior results in enhancing the growth of plants and, specifically, for speeding the photosynthesis process. Unprocessed hair removed from the scalp of African American people appears dead and dry but, in fact, includes moisture near the base, fiber, and melanin capable of holding the water for slow release later. Collected hair may be deposited into a specialized cleaning assembly for cleansing, infusion with fertilizer, and agitated for needle felting into a mat, balls, or powder for application to the roots of a plant for slow release of water and fertilizer held in the hair so that the plant receives melanin protein.
