An exemplary system and method for collecting and processing floating solid debris from a body of water on a vessel includes a debris recovery conveyor extending off the vessel and which receives floating solid debris from the body of water and delivers it to a first debris processor which fragments at least some of the debris received into smaller debris pieces.

A floatable-material harvester is disclosed, including vacuum source, transport hose, and a floatable-material receiver. In one embodiment, the transport hose has at least one air inductor/intake along its length, which allows air to enter the transport hose to accelerate its contents, by negative pressure air induction. In another embodiment, a transport hose has at least one floatable-material thruster along its length, comprised of at least one nozzle, which provides pressurized fluid (e.g., air or water) in the direction of the flow of the harvested floatable material by positive pressure induction. A method is disclosed whereby the floatable material harvester is used to harvest an absorbent material (e.g., wood chips, straw, perlite, zeolite, polypropylene mesh, titanate nanofibres) that has absorbed a pollutant (e.g., oil, solvent, radioactive isotopes) from a beach or in water.

A multifunctional ship for the collection and recycling of ocean debris and the system thereof may include a hull; a detection device provided on the hull to detect ocean debris floating on the sea or deposited on the seabed; a collection device installed on the hull to collect the ocean debris detected by the detection device; a sorting device installed on the hull to sort the ocean debris collected by the collection device; a compressing device installed on the hull to compress the sorted ocean debris to compress and remove moisture and reduce the volume; a waste plastic recycling device installed on the hull to produce recycled oil by thermally decomposing the waste plastic compressed in the compressing device; a storage tank installed at the bottom of the hull to store the recycled oil produced; and a purifier for purifying wastewater generated in the process of producing recycled oil.

A method of fabricating an coating includes providing a coating comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD), or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the coating to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The coating is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with a material.

A system for cleaning rivers and waterways in general includes one or more floating modules, each having a floating body and a rotating body provided with projecting elements configured to be positioned on the water surface, so that, when the rotating body rotates due to the thrusting action of the water current, the projecting elements move floating debris in a direction determined by its rotation direction towards an accumulation or recovery area.

A vessel for control of aquatic plant species (100) in seas, rivers and lakes that is configured to extract from the surface of the water and hoist to a deck of the vessel (100) a plurality of plant remains of a given aquatic ecosystem by means of an elevator belt (101); and/or receive from a coastal installation a plurality of aquatic plant remains mixed with grey water from coastal human settlements; and that is characterized in that the remains of aquatic plant species extracted from the surface of the water and/or received from coastal human settlements are deposited in a cooking chamber (102) where they are subjected to controlled temperature conditions configured to modify, ferment and rot said remains preventing their reproduction.

A novel water-borne debris collection system integrated into a waterborne vessel for collecting surface and near surface debris in a body of water, such as a river, lake, or ocean. The apparatus may include a solid collection boom that projects laterally from a vessel and is partially submerged to act as a collection mechanism. The boom also facilitates the propulsion of the vessel by providing a barrier across which a differential water surface level may be created to drive the vessel forward. The apparatus may include a pumping system that draws water from the anterior side of the screen and for multiple purposes, including processing the collected water to remove plastics and other pollutant and debris material therefrom, and to transfer the water to the posterior side of the screen to create the differential water level for driving the vessel forward.

A water surface garbage salvaging device, comprising a demihull, a large garbage salvaging device and a small garbage cleaning device; wherein the large garbage salvaging device is arranged on a front portion of the demihull, and the small garbage cleaning device is arranged on a rear portion thereof; the large garbage salvaging device comprises a paddle wheel, slipways and a large garbage storage bin; and the small garbage cleaning device comprises a filter mesh, a guide rail slider mechanism, a lifting mechanism and a pulley system, a hanging bracket is arranged above the filter mesh.

The present invention relates to an algae collection device and, in particular, to an algae collection device using an escalator-type lift equipped with a screen having a level state. The present invention may collect algae using an escalator-type lift equipped with a screen having a level state while the algae do not move down. The present invention may effectively collect, into a collection box, the algae transported on the escalator-type lift by means of compressed air generated by a compressor.

An oil spill retrieval system for retrieving spilled oil from the surface of a body of water and including a boat having means for collecting the oil from the water surface and having means for processing the collected oil. A pontoon boat that collects spilled oil from the ocean through a hair roller system suspended between the pontoons. Human hair is present within a porous casing of the roller and Oil floating on the water enters the porous casing whereupon the oil is absorbed by the human hair, wherein the absorbed oil is pass through one or more pipes to go into large pontoons which are the main oil collecting tanks on the pontoon boat.
