A method for preparing a plant derived product or a process intermediate or a process input, the method comprising the steps of providing a plant derived starting material, subjecting the starting material to a forward osmosis step against a draw solution so as to produce a plant material concentrate, and subjecting the draw solution to a water removal step. The water removal step may include further forward osmosis in combination with an evaporator system.

The present disclosure relates to environmentally-clean thermal drying systems and methods. In accordance with one aspect, a method for thermal drying includes receiving a grease-related waste, burning the grease-related waste in a furnace to generate heat energy, receiving a bio-waste in an indirect dryer at an adjustable feed rate, drying the bio-waste in the indirect dryer using at least some of the heat energy, and metering the bio-waste into the indirect dryer at the adjustable feed rate. The adjustable feed rate is adjusted based on a percentage of solids of the bio-waste before entering the indirect dryer and a temperature within the indirect dryer, where the indirect dryer and the adjustable feed rate are coordinated to achieve a predetermined percentage of solids in a dried bio-waste exiting the indirect dryer.

This invention provides a method of preparing organic fertilizer by combining agricultural wastes and livestock manure, belonging to the technical field of preparing organic fertilizer. 1. Collect agricultural wastes. 2. Crush agricultural wastes to fragments of 1-4 cm in length after removing debris, and make a composting bed, 110-160 kg per cubic meter. 3. Prepare maturing agent: Put water into a plastic container at room temperature for 24 hours, then add maturing agent, such that the mass ratio of water to maturing agent is 1000:5, stir, and leave it 24 hours after stirring. Then spray evenly on the composting bed. 4. After step 3, the water content of the compost is controlled at 55%-65%; the bulk density is controlled at 110240 kg/m{circumflex over ()}3; and the proportion of raw materials is treated by slot chelation. 5. livestock manure is sprayed evenly on the composting bed every day, and the sewage of livestock and poultry manure is controlled at less than 85%, and 850 kg of livestock and poultry manure is sprayed on every cubic meter of the composting bed every day. Fermentation 1 to 2 months later.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.

A food recycler includes a base, at least one air intake opening, a gearbox, and a motor. An airflow component is on top of the motor. A fan is configured on the airflow component and a filter is positioned at an output port of the airflow component. A bucket receptacle is configured on the gearbox. The fan and the filter are configured adjacent to an upper portion of the bucket receptacle. A casing has a lower rim complimentary to a base rim. The casing has an interior volume complimentary to a fan module and an interior volume complimentary to an air filter module. A control switch and lid latch are configured in the casing and next to each other. A lid is hinged to the casing such that air flows from a bucket through the lid to the fan and back from the filter to the lid and out an exhaust vent in the lid.

A fortifier for growth and flowering in horticulture, trees and ornamental plants, aromatic plants and fruit trees, from wastewater from brewer's yeast with a very low protein concentration. Its attainment is comprised of the previous stages: filtered by 80 m; magnetic treatment of the liquid; addition of 0.1 to 20 g/l phosphate and 10 to 20 g/l glycose. Fermentation is carried out keeping the free amino acid content greater than 0.1%, the content of Mg.sup.+2 greater than 0.1%, total nitrogen, phosphate, and potassium below 3.0%, the content of protein from 0.5% to 1.0% and EDTA from 0.02% to 0.2%, all by dry matter weight; addition of microbes from the environment; at temperatures of 15 C. to 40 C. with gentle agitation, for 24 hours to 30 days; subsequent filtering and pH adjustment. It has been found to be effective in various crops.
