The present invention relates to a process for preparation of polyethylene-cork composite panels comprising the steps of: mixing 10-64% of cork granulate and 36-90% of polyethylene granulate at room temperature, and feeding a press with this mixture; compressing this mixture in the press with a compression force in the range of 300-450 kN, at a temperature in the range of 160-200° C. and for a hot compression time between 24-180 seconds; and cooling to room temperature, with a compression force between 350-450 kN, for a cold compression time between 32 and 240 seconds; to obtain panels with a thickness between 3 and 5 mm. The invention further relates to a polyethylene-cork composite panel and also to use thereof in the construction industry, particularly as cover board core.

The present application relates to a product made with food processing by-products/wastes in particular from the cocoa and chocolate industry, the coffee roasting industry, the wine and distillery industries, the beer industry, the olive oil industry and the fruits and vegetables industries, mixed with a binder, preferably a bio-based binder. The present application also relates to the method of manufacturing the product.

The present invention relates to a method for manufacturing processed cork chips, and a floor construction method using the same. The processed cork chips are manufactured by the method, including: crushing and drying cork chips; adding polyurea to the dried cork chips to prepare a mixture; heating the mixture to cure the same; and cooling the cured mixture. Further, the floor construction method includes: laying the processed cork chips on the surface of a floor formed of concrete, a water-permeable base layer or crushed stone with a solidified top surface; and flattening the processed cork chips and pressing the same by means of a roller at a fixed temperature.

This invention refers to a method for producing magnetic cork particles comprising the steps of providing a composition of an alkaline solution and cork particles, with a size comprised between 1 nm and 2 mm, and stirring; Adding an acid solution containing Fe.sup.3+ and Fe.sup.2+ cations to the composition to cause the magnetization of the cork particles and maintaining the stirring; Filtering the solution obtained to obtain a magnetized cork particles precipitate, and washing the precipitate with water until the washed solution reaches a pH comprised between 4 and 7, and let dry until obtaining stabilized magnetized cork particles, wherein the magnetization of the cork particles is due to the formation of a magnetite coating on the particles, being the magnetite adsorbed on the particle surface. It also refers to magnetized cork particles thus obtained and their uses.

A cork derived product formed by a bonded mass of granulated and/or microgranulated cork particles and activated carbon particles mixed with the cork particles; wherein the cork particles and the activated carbon particles are bonded together by means of a binder; and the cork derived product includes the activated carbon particles in a proportion between 10% and 40% of the dry weight of the product, giving the cork derived product a darkened color.

A privacy apparatus includes one or more substantially cork panels. Each panel can be configured to provide visual and/or sound privacy for a certain work space. The panel can be supported on a floor via one or more base elements and/or may be reinforced in rigidity and/or strength via one or more supports. Some embodiments of the apparatus can include a first panel and a second panel attached together via one or more supports press fit within openings defined in rear faces of the panels.
