Abstract: A composite board is made from waste medium density fiber (MDF) board or waste particle board that includes solid urea formaldehyde. The waste board is chopped and milled into particles having a size between 20 mesh and 150 mesh, creating a waste flour. After removing moisture from the waste flour, the dried waste flour is mixed with a thermoplastic to bind and encapsulate the waste flour. Internal lubricants are added to improve the flow characteristics of the blended material, and external lubricants are added to present sticking of the mixture to an extruder or mold. Mineral fillers are added to improve the flexural modules of the composite board, and a plasticizer can be added to improve the physical properties or mechanical characteristics of the mixture. An ultraviolet absorber, a biocide, and a pigment can also be added. The blended material is extruded or molded into a desired shape. When cooled, the thermoplastic hardens to form a solid composite board.

Abstract: System, method, and apparatus for carrying out the multi-level stacking and moving of merchandise units using lift trucks configured for slipsheet palletizing. The system employs a blocking assembly in conjunction with slipsheets employed for such warehousing practices. This blocking assembly preferably is formed of a corrugated polymeric material having a forward flap-like blocking component which extends downwardly from a die-formed crease over the packaged components of a lower assembled merchandise unit. The crease provides sufficient compressive stress distribution from abutting engagement with an errant lift truck forward fork tip to avoid damage to upper level packaged merchandise within the lower unit. The blocking assemblies are quite light and thin, and the flap-like blocking components thereof may be utilized as a slipsheet in the event that the grasping tab of a slipsheet is torn by the gripping mechanism of a lift truck.

Abstract: A structure for a vertical unitized compartmentalized sorting/holding container compatible with plastic bags for use where sundry recyclable materials are generated and discarded. There is provided a retaining apparatus in which the action of discarding, at the same time, sorts and holds various materials for recycling purposes in several sloping rhomboid compartments, one over the other, providing fifty per cent greater holding volume than level rectangular compartments of the same floor space. Further, dull hooks advantageously located hold plastic bags open for filling from the front instead of the top. Pull-down doors, render easy loading, and serve to isolate odors and obscure trash from view. Flat newspaper storage is provided in the bottom. The construction of the container provides for free-standing use in interior or exterior environments and flush in-wall installation.
