A methods and systems for desalination and decontamination for solid waste are disclosed, including a method comprising decontaminating a volume of contaminated, desalinated drill cuttings by removing at least a portion of contaminants associated with the contaminated, desalinated drill cuttings, the desalinated drill cuttings being drill cuttings that have been desalinated by a desalination unit.

The present invention pertains to a method for producing high value-added compounds from polyethylene terephthalate. More specifically, the present invention demonstrates that a monomeric terephthalic acid obtained from the chemical hydrolysis of polyethylene terephthalate can be converted to high value-added aromatic compounds and aromatic-derived compounds, and ethylene glycol, which is another monomer of polyethylene terephthalate, can be converted to glycolic acid, which is a cosmetic material. The present invention is characterized by recycling polyethylene terephthalate waste into high value-added compounds.

Preparing a microbially desulfurized crumb rubber includes combining microorganisms capable of breaking crosslinked sulfur bonds, sulfur-containing crumb rubber, and a salt solution to yield a mixture; combining a buffer with the mixture to yield a buffered mixture, thereby adjusting a pH of the mixture; providing oxygen to the buffered mixture; incubating the buffered mixture for a length of time to yield a microbially desulfurized mixture; combining the microbially desulfurized mixture with bitumen to yield a precursor; and heating the precursor to yield the microbially desulfurized crumb rubber. The microbially desulfurized crumb rubber can be combined with bitumen to yield a modified bitumen. The modified bitumen can be combined with asphalt to yield a modified asphalt.

There is provided microbial compositions and methods for producing thereof and use of compositions thereof in treatment of contaminated soil, water, and/or surfaces. In one aspect, there is provided method for reducing microbial contamination of a microbial contaminated body, the method comprises: inactivating resident vegetative microbiology from an extract obtained from a contaminated of body to inactivate the resident vegetative microbiology in the extract, selecting one or more soil-based microbes suitable for growth in the contaminated body, growing the one or more soil-based microbes with the inactivated extract to allow the one or more soil-based microbes to adapt to the inactivated extract, releasing the one or more soil-based microbes into the contaminated body where the one or more soil-based microbes dominate and reduce microbial contamination of the microbial contaminated body.

A waste treatment system includes: at least one reformer for hydrolyzing waste; and a microbial reactor for microbially degrading a reformed material containing at least a solid among the waste hydrolyzed in the at least one reformer.

A device and method for cleaning polluting particles and debris out of a body of liquid using a swimming robot which catches debris with filters and chemically reduces the caught debris into a preferred byproduct before ejecting the byproduct back into the environment. In a preferred embodiment and application, a swimming robot made of biodegradable materials and equipped with non-toxic enzymes for chemically reducing plastics is placed into the ocean to swim around, propelled by wave motion, and safely remove plastics, particularly including microplastics, from the environment and convert the filtered plastics into a benign byproduct, until the device itself wears out and harmlessly breaks down without being recovered or polluting the environment further.

Various waste fractions from meat, gravy, and animal feed industries, that are difficult to recycle, as well as wastes, for example, from fishing and fish processing, are often challenging to separate for further processing into products. The hygienic and otherwise safe and economical utilization of these, consistent with ecologically sustainable development, requires the development of new methods. According to the method and apparatus of this invention, with the help of microbes and their enzymes, for example, bone and tissue waste, as well as protein, fat material or materials containing blood matte, that have been separated during meat processing, can be fractioned into new raw materials. Gained products can be, for example, energy fractions and gases, waxes and various organic fertilizers and soil improvement substances.
