A method of recycling a used absorbent article having human waste includes: a first step of separating pulp fiber from the used absorbent article to obtain regenerated pulp fiber; a second step of conversion to solid fuel from constituent materials of the used absorbent article remaining after separation of the pulp fiber to obtain solid fuel, and a third step of supplying waste water containing organic material generated from the first step to a microbial fuel cell to obtain electric power while purifying the waste water. The processing rate for the used absorbent article containing human waste is 90 mass % or greater.

The invention relates to a method in which a starting material for injection-molding, having a viscosity of between 0.50 and 0.7 dL/g, is produced with the aid of a chain breaker from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector. A chain breaker is added to the rPET material in the melt of the recycling extruder and/or preferably the melt of the injection unit in order to lower the viscosity and to enrich the PET with copolymers.

A system and method for recycling and repurposing used tires. The system includes a plurality of modules for automatically repurposing used tires into fabrication of structural members or devices including but not limited to tie-downs, attachment cables, speed bumps, tire chocks, pet scratching posts, fencing, safety barriers, and more. The treads of the tires are used for making elongated strips which are joined using adhesive(s) for forming structures. In some embodiments, the temperature and pressure for the repurposing process can be adjusted using an interface. The used tires are cleaned and waste material is removed after treads are separated.

A method of forming blocks having dimensional uniformity thereacross associated with building construction includes shredding, via a shredder, a non-recyclable plastic waste raw material having a specific dimensional length and a height into a number of strips having a uniform dimensional width of 0.120 inches to 1 inch, and weighing the number of strips at a weigh apparatus. The method also includes isolating and batching the number of strips collected and weighed, and compressing the isolated and batched number of strips in a compression chamber to form a block based on steam-sanitizing the isolated and batched number of strips in the compression chamber with steam having a temperature varying from 220? F. to 850? F. and a pressure of 30-500 Pounds per Square Inch (PSI) and introduced intermittently across regions of the compression chamber to solely activate a base polymer of each of the isolated and batched number of strips.

The present invention relates to a bottle label removing and cleaning integrated system, including a support platform, and further including a label removing and cleaning machine, a bouncing separation screen, a cleaning liquid separator, and a cleaning liquid buffer tank that are sequentially connected, where the label removing and cleaning machine is mounted on the support platform, the bouncing separation screen is configured to separate cleaning water, labels, and impurities from main materials, and the cleaning liquid buffer tank is configured to accommodate cleaning liquid purified by the cleaning liquid separator.

Methods are provided for making and recycling recyclable food grade plastic products from recycled, post-consumer plastic. The recyclable food grade plastic products may have wash away labels with printed text, graphics, or images that can be easily removed such that the plastic product may be recycled into FDA-approved food grade (i.e., food safe) plastic that is capable of being reused to manufacture new recyclable food grade products.

A multi-axis variable-speed hot washing machine is provided, including a cleaning chamber, a drive apparatus, and a rotation mechanism. The rotation mechanism is arranged in an inner cavity of the cleaning chamber and is in transmission connection with the drive apparatus. At least one or more groups of rotation mechanism is arranged. The inner wall of the cleaning chamber is provided with a scraping mechanism that enhances a squeezing and frictional cleaning effect on a to-be-cleaned material.

An ultrasonic cleaning machine for recycling and cleaning plastic, including a support assembly and a cleaning body, the cleaning body being mounted on the support assembly, the cleaning body being provided with a cleaning chamber for material cleaning, the cleaning body being provided with a plurality of ultrasonic vibrators for transmitting ultrasonic waves into the cleaning chamber, and the plurality of ultrasonic vibrators being distributed in the interlayer of the cleaning body. When cleaning a material, the material is evenly transported into the cleaning chamber through a feed apparatus. There is a liquid cleaning medium inside the cleaning chamber. When the material passes through the cleaning chamber filled with the cleaning medium, the ultrasonic waves generated by the plurality of ultrasonic vibrators form a cavitation effect to clean the material.

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

Example implementations include a system and method of using plastic from bodies of water and creating a floating platform by collecting plastic from a body of water, cleaning the collected plastic, melting and compacting the plastic, molding a plurality of hexagonal blocks from the compacted plastic, stacking the plurality of hexagonal blocks, wherein a system of springs and an energy storage device is provided between each of the plurality of hexagonal blocks, and coating the stacked blocks with a non-toxic material. Through the use of various onboard functionalities, energy may be generated to regulate temperature and provide electricity, oxygen may be supplied, and water may be purified.
