The present disclosure generally relates to collecting, handling, and / or sorting of waste or other objects. For example, certain embodiments are generally directed to systems and methods for collecting and sorting objects such as trash, recyclables, compostables, etc. In some cases, such systems may be used at a MRF (materials recovery facility), a transfer station, a public facility, or other locations where various objects in a waste stream are to be sorted. In some cases, the system may be relatively small and compact. The waste stream may be singulated or separated into discrete objects to facilitate identification and sorting. For example, two or more discrete objects within the waste stream that are contacting one another or are proximate to one another may be separated, so as to facilitate identification and / or sorting of the objects. This may be useful, for example, for producing less contaminated streams of trash, recyclables, compostables, etc. from a waste stream.

Methods of capturing carbon in biochar are provided. The method includes mixing the biochar with an alkaline solution to form an intermediate mixture, and exposing the intermediate mixture to a CO2 source to precipitate calcium carbonate over and in the biochar to form a CO2 weathered biochar. In some cases, the method further includes injecting CO2 into the alkaline wastewater to sequestration / store CO2, which may then be used as mixed water for the production of cementitious composites. The method can be used for upgrading three waste streams, and the treated CO2 weathered biochar maintains the compressive strength of the obtained concrete when replacing part of the pre-cured cement and aggregate components. In addition, the treated CO2-weathered recycled aggregate maintains the mechanical strength of the obtained concrete when replacing part of the aggregate.

An example method comprises H2S filtration, compression, and cooling of the CO2-rich tail gas, subsequent filtration of oil, water, VOCs, and other sulfur-comprising compounds from the CO2-rich tail gas, and subsequent drying and compression of the CO2-rich tail gas.
