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.

Provided is a method for processing electronic and electrical device component scraps, which can selectively recover a substrate scrap including a substance intended to be recovered. A method for processing electronic and electrical device component scraps, including separating a substrate with lead wires contained in the electronic and electrical device component scraps before sorting the electronic and electrical device component scraps by magnetic sorting.

Plastic waste is shredded and formed to a desired shape and held together using a binder and/or heat, etc. The resulting composite material may be useful for building and/or furniture and/or flooring, etc. (similar to wood composite board). In some embodiments, the board is highly water resistant. Optionally, the board is made of layers. For example, an inner layer has reduced density and/or an outer layer may have decreased particle size and/or increased fiber content.

A method of making a recycled plastic product includes collecting recyclable plastic materials. The recyclable plastic materials are separated into a plurality of single grade batches of recyclable plastic materials. Each single grade batch is ground into a single grade group of recyclable plastic chips. A single grade portion is weighed out from each single grade group of chips. Each single grade portion is equal in weight within a range of plus or minus 15 percent. Each single grade portion is mixed together to form a multiple grade mixture of recyclable plastic chips. The multiple grade mixture is heated to form a multiple grade blend of molten recyclable plastic. The multiple grade blend is cooled into a form of a solid recycled plastic product. The recycled plastic product comprises multiple grades of recyclable plastic and a volume large enough to encompass a 1.0-inch diameter sphere.
