A multipurpose fertilizer composition comprising an after incubation mixture, a moisturizing ingredient, and a ylang ylang extract ingredients; wherein, the ylang ylang extract ingredients from fresh ylang ylang flowers that can be chopped/or not shredded and soaked in a liquid such as water or solvent for a long time to extract the necessary compound components from the infused ylang ylang flowers into the liquid; wherein, the ylang ylang extract ingredients containing at least 0.05% by weight of a cinnamyl acetate. Besides, the present invention is to provide a process of manufacturing the multipurpose fertilizer composition using ingredients source material from mixing a manure ingredient with a poultry manure ingredient, and an organic waste ingredient.

The invention relates to a method and system for phosphate recovering from a waste stream, such as an animal manure waste stream. The method comprises the steps of: - providing a tank reactor, 5 - providing acidogenic bacteria and/or acetogenic bacteria and the waste stream to the tank reactor, - hydrolysing the waste stream, forming a reaction mixture; - providing a gas flow to the reaction mixture for removing carbon dioxide from the reaction mixture; 10 - providing the reaction mixture to an anaerobic sludge reactor, - removing a compound comprising phosphate from the reaction mixture within the anaerobic sludge reactor, and - removing gas from the reaction mixture within the anaerobic sludge reactor.

A bioreactor (1, 2, 3) and use thereof for converting organic residual and/or waste materials into an organic nutrient solution with a proportion of at least 10% plant-available mineralized nitrogen relative to the total nitrogen content of the nutrient solution. A process for preparing an organic nutrient solution is also provided, as well as an organic nutrient solution, use of an organic nutrient solution as an absorbent for carbon dioxide storage, use of an organic nutrient solution as an agent for binding carbon in plants and soils and to a nutrient production and carbon dioxide storage system.

The present disclosure relates to the field of ecological restoration of a coal gangue hill, and in particular, to a solid waste-based porous material, a method for preparing the solid waste-based porous material, and a method of ecological restoration of the coal gangue hill by applying the solid waste-based porous material. A coal-based solid waste restoration material and mycorrhizal solid bacterial agent are mixed to restore the coal gangue hill, the coal-based solid waste restoration material is prepared by mixing coal-based solid waste porous materials, low-rank coal, and waste organic matter and adding a microbial quickly decomposition agent for aerobic fermentation and standing.

A biodegradable composite includes an organic matter and a porous material, wherein the organic matter has viable bacteria, and a total plate count of the organic matter is greater than or equal to 10.sup.4 CFU/g. The organic matter accounts for 40% to 80% of a weight of the biodegradable composite. The porous material accounts for 20% to 60% of the weight of the biodegradable composite. The biodegradable composite could instantly remove unpleasant odor and accelerate a decomposition process to form compost. A product containing the biodegradable composite is provided as well.

A method for using treated biochar to reduce the overall environmental impact of farming and minimize the carbon footprint of farms is provided. The method comprising engaging in one or more of the following practices: (1) combining treated biochar with feed or using biochar as feed for animals to reduce methane from enteric fermentation and increase animal health and nutrition; (2) combining treated biochar with compost, animal bedding or manure piles to reduce odor and increase nutrient retention; (3) applying treated biochar to lagoons to reduce odor and treat water; (4) applying treated biochar to pastures to increase pasture health; (5) applying treated biochar to crops to increase crop productivity, healthier roots and prevent fertilizer leaching; and (6) using the carbon negativity of a produced biochar to reduce the overall farm or ranch carbon footprint.
