In one embodiment, a fine-dispersion compounding apparatus includes a closed container into which solid material is fed; a boiler configured to introduce high-pressure steam into inside of the closed container; a rotating body configured to knead the solid material with liquid medium generated from condensed high-pressure steam by rotating inside the closed container; an open port configured to set internal pressure of the closed container to atmospheric pressure level by releasing a closed state of the closed container; a conveying port configured to convey kneaded mixture of the solid material and liquid medium from inside to outside of the closed container; a mixed dispersion unit configured to disperse the conveyed kneaded mixture and compounding material; a liquid-medium ejection unit configured to eject the liquid medium contained in the kneaded mixture; and an extraction unit configured to extract a composite compound of the compounding material and the solid material.

An aquatic plant biomass-based decomposable and antibacterial plastic masterbatch composition contains: environmental biodegradable polymer materials, aquatic plant fiber materials, natural decomposable polymer, antibacterial materials, mineral fillers, Bis (2-ethylhexyl) adipate (DOA), 1,1,1-Tris Methylolpropane 1,1,1-Trimethylolpropane (TMP), and silane coupling agent. Thereby, low cost, excellent mechanical properties, release of far infrared rays and antibacterial effect are achieved.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

Provided are a hollow spherical particle that has higher safety and can be prepared more easily. A hollow spherical particle that is a self-assembled body of lignin, the lignin having a content of -O-4 ether type structure of 50% or more and a solubility in 60 to 80% ethanol at 25 C. of 2 w/v % or more.

Described is a method of producing a thermoplastic dispersion or binder from virgin and/or waste plastic and the use of the dispersion or binder to produce a thermoplastic composite product, such as a composite board. A portion of the thermoplastic may be treated using heat and/or a catalyst, or reacted with a coupling agent to produce a functionalised thermoplastic, and/or dispersed in water under agitation to produce a thermoplastic dispersion.

The present invention relates to a bonding resin useful for example in the manufacture of insulation, such as mineral wool insulation or glass wool insulation. The invention also relates to a method for preparing the bonding resin and to the use thereof.

Disclosed is a composition comprising (a) a lignocellulosic material and/or a cellulosic material; and (b) a cellulose derivative. A process for preparing the composition is also disclosed. The process can comprise providing a cellulose derivative in a solvent; and mixing a lignocellulosic material and/or a cellulosic material into the solvent. The lignocellulosic material and/or the cellulosic material can comprise 90% of particles ranging from 0.01 to 5 mm in size. The lignocellulosic material and/or the cellulosic material can be derived from a biomass residue.

Thermally expandable microspheres comprise a polymeric shell surrounding a hollow core, wherein the hollow core comprises a blowing agent, and the polymeric shell comprises isolated lignin.

Expanded microspheres include a polymeric shell surrounding a hollow core, wherein the exterior surface of the polymeric shell is free from particulate deposits originating from a solid suspending agent.
