The present disclosure relates to a home compostable label and its facestock, and a method for manufacturing such label and facestock. The facestock comprises a core layer comprising a top surface, a bottom surface, and a core compostable material; and a first skin layer comprising a first compostable material, said first skin layer being positioned proximate to at least a portion of the top surface of the core layer.

The subject invention provides improved methods for processing livestock waste, namely, for solid-liquid separation of manure, utilizing microbe-based products. In preferred embodiments, microorganisms and/or microbial surfactants are utilized to improve solid-liquid separation of livestock manure in ways that enhance the value of manure-based fertilizers to farmers and reduces greenhouse gas and other polluting emissions resulting from manure storage.

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.

A method and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance of the manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. The bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, the bedding material is dried (without a compacting step) to form a product. In yet another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.

The present disclosure provides a joint control method for nitrogen and phosphorus emissions in farmlands, comprising: reducing nitrogen and phosphorus input during crop sowing or planting by applying composite organic material and chemical fertilizer, wherein the composite organic material comprises: 200-250 parts of edible fungi residues, 300-350 parts of charcoal and 5-10 parts of rhamnolipid; constructing a nitrogen-phosphorus retention layer by utilizing composite microbial agent in combination with 150 parts of edible fungi residues and 20 parts of straw-based hydrogel; constructing a barrier layer by utilizing composite material, and controlling downward leaching of nitrogen and phosphorus that are not absorbed by crops, wherein the composite material of the barrier layer comprises: 25-35 parts of straw-based hydrogel, 20-30 parts of edible fungi residues, 35-55 parts of bentonite and 5-10 parts of corn flour.

A system and method for converting food waste and other biologically-derived waste materials into nutrients for an algal growth system using worms to produce such nutrients is described. In one embodiment, a method for converting food waste into nutrients for an algal growth system using worms includes providing food waste to a container including a plurality of worms. The method also includes collecting castings from the food waste processed by the plurality of worms. The method further includes providing a wash to the container. The wash causes the castings to move to a bottom portion of the container adjacent to a moveable screen. The method includes actuating the moveable screen so that the castings pass through a plurality of holes in the moveable screen. The method also includes providing the passed castings to an algal growth system.

A method for improved anaerobic digestion is presented. The method includes mixing a volume of waste material with water to form a feedstock mixture. The volume of waste material includes an initial amount of biomass and the feedstock mixture includes methanogenic bacteria either naturally present in the waste material or introduced artificially. The method also includes introducing one or more promoter substances to the feedstock mixture. The one or more promoter substances are capable of modifying the methanogenic bacteria. Modifying includes stimulating novel enzyme production in the methanogenic bacteria.

Microorganisms and bioprocesses are provided that convert gaseous substrates, such as renewable H.sub.2 and waste CO.sub.2 producer gas, or syngas into high-protein biomass that may be used directly for human nutrition, or as a nutrient for plants, fungi, or other microorganisms, or as a source of soil carbon, nitrogen, and other mineral nutrients. Renewable H.sub.2 used in the processes described herein may be generated by electrolysis using solar or wind power. Producer gas used in the processes described herein may be derived from sources that include gasification of waste feedstock and/or biomass residue, waste gas from industrial processes, or natural gas, biogas, or landfill gas.

A bioreactor for growing micro-organisms in a reaction mixture including a reaction medium and micro-organisms. The bioreactor includes a first reaction chamber, a second reaction chamber and means for connecting the first reaction chamber to the second reaction chamber. The first reaction chamber has first volume for containing first number of micro-organisms, a first input for providing reaction mixture thereto, and a first output for removing excess gases therefrom. The second reaction chamber, arranged downstream from first reaction chamber, has a second volume for containing a second number of micro-organisms, a second input for providing gases thereto, and a second output for removing reaction mixture therefrom. The means for connecting is the sole input for allowing the reaction mixture to flow from the first reaction chamber to the second reaction chamber and for gases to flow from the second reaction chamber to the first reaction chamber.

A novel material size reducing and storage device system comprising of a composting system and a three-dimensional (3D) printing system is disclosed. The compost system is configured to facilitate material size reduction of compostable material. The 3D printing system is configured to facilitate 3D printing of one or more objects using material that have been reduced to a predetermined size.
