The present description relates to press extractors for processing municipal solid waste or source separated organics, and can have large perforations for separation of a wet fraction from a liquid depleted fraction. The extractor can also be operated based on a target plug thickness of the liquid-depleted plug left over in the perforated chamber after compression. The extractors can facilitate good organics extraction yields, and lower operating pressures, among other benefits.

Disclosed is a method for promoting anaerobic digestion using carbonyl iron, relating to the technical field of biological fermentation. The method includes the following steps: adding carbonyl iron into a fermentation broth for anaerobic digestion. According to the present disclosure, a substrate added in the fermentation broth is animal manure, kitchen waste or tail vegetables.

An under-sink composting device configured to operably couple with a garbage disposal. The composting device includes a waste separator for separating solid waste from liquid in an organic waste material.

The present disclosure refers to a method of electrochemical conversion of organic waste to organic acid and hydrogen, comprising the steps of: (i) subjecting organic waste to ball milling under alkaline or acidic conditions to obtain pre-treated organic waste; (ii) introducing the pre-treated organic waste to a first compartment of an electrochemical cell, wherein the electrochemical cell comprises: the first compartment containing a nickel-based anode, a second compartment containing a cathode, and an electrolyte; and (iii) applying an electrical potential between the anode and the cathode, thereby producing organic acid at the anode, and hydrogen at the cathode. The present disclosure also refers to an organic acid or hydrogen produced from the method disclosed herein.

Provided is a food waste disposer. The food waste disposer according to an embodiment of the disclosure includes: a housing; a grinder detachably installed inside the housing and configured to grind food waste accommodated therein; and a deodorizer positioned to a side of the grinder, and configured to suck a smell generated from the grinder and discharge the smell to outside of the housing, wherein the grinder includes: a grinding case; a rotating grinder including a plurality of blades rotatably installed at different heights inside the grinding case; and a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case.

A safe, odorless system to capture food waste in a base of sodium reduced and concentrated sea minerals held for beneficial reuse that becomes a catalyst for enhanced carbon capture while increasing the value of this waste towards this objective. This invention enables recapture of waste on a massive scale. This system may invigorate our agricultural economy and impact climate change. This is connected to part two of this patent, Part twoCustomization of the catalyst for maximum carbon capture and to Part Three of this patent, Part Threean economic method to use and maximize use of the carbon capture properties on a massive scale.

The present invention relates to a biodegradable disposable article comprising: unmodified and naturally occurring food waste comprising cellulose or hemicellulose in the range of about 5 wt % to about 70 wt %, less than about 80 wt % carbohydrate and at least about 2 wt % of lignin; wherein the food waste is optionally dehydrated and/or optionally agitated to form particulate solid material before being moulded under pressure of at least 5000 kg/cm.sup.2 and at a temperature of at least 150 C.

Provided is an energy-saving, environmentally friendly biogas generation system that can reduce the generation of digestive fluid, can efficiently cause methane fermentation by removing ammonia in organic matter regardless of the freshness of the organic matter. The biogas generation system includes a sealed container 2 that contains the organic matter, a stirrer 3 that stirs the organic matter contained in the sealed container 2, a gas-fired boiler 4 that heats the inside of the sealed container 2 to a predetermined temperature, a vacuum pump 5 that reduces pressure in the sealed container 2, and a storage tank 6 that stores biogas generated by methane fermentation of the organic matter in the sealed container 2. Part of the biogas stored in the storage tank 6 is supplied to the gas-fired boiler 4 as fuel.

An apparatus tears, breaks or divides into several parts the casing of capsules and/or pods containing coffee or other infusions, which allows the organic part contained therein to be separated from the recyclable part, consisting of the casing made of aluminum or plastic. The apparatus includes a perforated basket directly connected to a pipe arranged at the top, for feeding the empty pods or capsules, conforming the geometry of the system to eliminate the feeding pipe arranged by the side (which was subject to constant dirtying by the organic contents subjected to centrifugal force). The basket contains a tearing unit and has at least one opening at the top, the size and shape of which adjust the stay time of the capsules in the perforated basket or separation compartment. A cleaning unit cleans externally the perforated basket from the residues, which obstruct the side holes of the perforated basket.
