Abstract: A disposable eggshell eco-friendly material and manufacturing method are disclosed. The disposable eggshell eco-friendly material, for volume ratio, includes 50%-80% of calcined eggshell powder, 10%-48% of biodegradable polymer, 1%-5% of natural degradation agent, and 1%-5% of natural binding agent, which are subjected to a mixing and stirring step according to such ratios, and then subjected to a pelletizing step to be first prepared as a plurality of disposable eggshell eco-friendly material pellets, and the disposable eggshell eco-friendly material pellets being then subjected to a shaping and forming step by means of one of film blowing, extruding, vacuum forming, bottle blowing, injecting, and drawing, to obtain a disposable eggshell eco-friendly material product that is disposed of after one time of use.

Abstract: An oyster paper and a manufacturing method thereof are provided. The oyster paper is made of 60%-70% oyster shell powder, 10%-20% polymer, 15%-17% natural biodegradation inducing agent, and 3%-5% natural biodegradation assisting additive agent, by volume ratio, which are subjected to mixing and pre-melting processing, followed by compounding and pelletizing to prepare oyster paper pellets, which are then subjected to film blowing processing to be film-blown into an oyster paper product having a thickness of 0.05-0.5 millimeters. The oyster paper possesses the quality of wood pulp paper and shows bettered stiffness and wider applications. The oyster paper also provides, after being disposed and buried, an effect of being 100% natural degradation into compost for fertilizing the soil. As such, a kind of oyster paper featuring recycling and reuse of oceanic creature waste shell and natural microorganism induced degradation for composting and recycling and a manufacturing method thereof are provided.

Abstract: A device provides for connecting and holding up two adjacent pieces of floorboard each including on its underside, two longitudinal grooves, two transverse grooves across the longitudinal grooves and two L-shaped longitudinal recesses along both sides. The device comprises two identical sections each including a plurality of longitudinal and transverse troughs at its underside and a plurality of longitudinal and transverse latched elements at its upper side. The latched elements of one section are snapped into the grooves and recesses of both pieces of floorboard and the latched elements of the other section are snapped into the troughs of one section respectively. Thus, the invention can connect a plurality of pieces of floorboard together.

Abstract: A wooden floor board includes a board body and a connector. The board body has two lengthwise ditches formed in the bottom surface. In a preferred form, each lengthwise ditch has a cone-shaped section formed in the innermost section. The elongate connector has two lengthwise upright insert members at two opposite lengthwise sides to engage one of the two lengthwise ditches of two neighborin board bodies. The connector is laid under two neighboring board bodies en assembling the wooden floor boards into a complete floor of a room. Any board body of the complete floor may easily be pried up with a tool like a screwdriver if it is broken and has to be replaced with a new one.

Abstract: A wooden floorboard assembly has a foamed plastic layer, a carpet layer disposed on the foamed plastic layer, at least a first and a second wooden floorboards. The first wooden floorboard has a first wooden plate, a first hook-and-loop-type fastener pad adhered on a bottom of the first wooden plate, and the first wooden plate having a first protruded portion and a first recessed portion. The second wooden floorboard has a second wooden plate, a second hook-and-loop-type fastener pad adhered on a bottom of the second wooden plate, and the second wooden plate having a second protruded portion and a second recessed portion. The first recessed portion of the first wooden plate engages with the second protruded portion of the second wooden plate.
