Systems and methods for composting cannabis-related waste materials are provided. The method may include obtaining a plurality of cannabis-related waste materials, physically altering, e.g., pulverizing, the cannabis-related waste materials to form a feedstock suitable for composting, and transforming the feedstock into compost. For example, the feedstock may be composted via at least one of a windrow method, aerated static pile (ASP), in-vessel digestion, or vermicomposting. The obtained cannabis-waste materials may have a predetermined ratio of carbon to nitrogen, and the physically altered cannabis-related waste materials may be altered to smaller particle sizes suitable as a pre-compost. For example, the physically altered cannabis-related waste materials may be unrecognizable and unusable, in compliance with local and state regulations.

A method for treating process material using a plurality of autoclaves, wherein each of the plurality of autoclaves cycles through the following: introducing steam from one or more of the plurality of autoclaves into an interior of a vessel; increasing the temperature within the vessel by adding heat to the interior of the vessel using an indirect heat source; reducing the temperature and pressure within the vessel by flashing a portion of the steam within the interior of the vessel to another one of the plurality autoclaves; increasing the temperature within the vessel by continuing to add heat to the interior of the vessel using the indirect heat source; and reducing a moisture content of the process material in the interior of vessel to a predetermined value by venting a remaining portion of the steam to another one of the plurality of autoclaves.

A fluid dispensing apparatus may be used to dispense a paint fluid from a paint container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the paint within the paint container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the paint to flow under the pressure out of the paint container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source separated from the vacuum container by an intermediate wall and a filter. The vacuum source is in pneumatic connection with the filter through the intermediate wall. A plurality of discharge conduits extend through the intermediate wall, extend over and above the filter, along the roof of the vacuum container. The plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

A method for remote control of decontamination of medical waste in an apparatus includes receiving, by a server via a first network interface and from the apparatus via a second network interface, a plurality of signals, the plurality of signals comprising operation data of the apparatus generated while the apparatus performs medical waste decontamination cycles in a first configuration; analyzing, by the server, the plurality of signals according to an operation policy; selecting, by the server, a first signal based on the analyzing the plurality of signals; and adjusting, by the server, operation of the apparatus by transmitting, via the first network interface, instructions to the second network interface of the apparatus, the instructions comprising the first signal, wherein receipt of the instructions causes the apparatus to perform a medical waste decontamination cycle in a second configuration different from the first configuration.
