An object of the present disclosure is to provide a method of recycling carbon fibers that allows efficiently obtaining carbon fibers suitable for reuse. An embodiment is the method of recycling carbon fibers that includes: preparing a carbon fiber reinforced plastic molded product containing a carbon fiber reinforced plastic containing a carbon fiber and a resin; performing a process of at least one of a heating process or an ultraviolet irradiation process on the carbon fiber reinforced plastic molded product; and removing the resin after the process from the carbon fiber by injecting a first liquid to at least the carbon fiber of the carbon fiber reinforced plastic molded product after the process.

Method of recycling carbon fibers

A processing method according to the present embodiment is a processing method of a fiber containing resin in which fibers are contained in a matrix resin. The processing method includes: a step of thermal decomposition of the matrix resin in the fiber containing resin; and a step of stirring a resulting fibers bundle in solvent after the thermal decomposition. At the time of the thermal decomposition, the matrix resin may be carbonized in a dry distillation-carbonization furnace, for example.

The object of the present invention is to provide a method for aggregating and separating algae dispersed in a liquid efficiently. According to the present invention, a method for aggregating and separating algae dispersed in a liquid, which comprises adding an alkaline inorganic aggregating agent to the liquid at pH of 2.0 to 4.0 in which algae are dispersed, followed by adding a cationic polymer aggregating agent, is provided. Further, according to the present invention, a method for producing biofuel utilizing algae is provided.

Method for aggregating and separating algae

The invention provides a method for manufacturing a molded woody article, which includes compression molding a base material containing wood fibers, polylactic acid fibers and an inorganic filler at a temperature not less than a melting point of the polylactic acid fibers, and maintaining the molded base material at a temperature close to a crystallization temperature of the polylactic acid fibers for a desired period of time, thereby crystallizing the polylactic acid fibers. In the molding step, the base material is entirely deformed and molded into a desired shape while the polylactic acid fibers are melted, and in the crystallizing step, the polylactic acid fibers are solidified, thereby producing the molded article. In the crystallizing step, polylactic acid crystallizes rapidly and reliably utilizing the inorganic filler as a crystal nucleating agent.

Process for producing woody molding

To provide a fiberboard capable of reducing a load on the environment at all states of producing, using, and abolishing and moreover having a high degree of bending strength and a high bending-strength retention rate at high temperature and high humidity so as to be usable for an automobile interior material or building material and a fiber-board producing method. The fiberboard is formed by mixing natural fiber with polylactic acid resin serving as a binder and has an apparent density of 0.2 g/cm.

Fiber board and its producing method

The polylactic acid composite material of the present invention comprises a polylactic acid, a low molecular weight compound which has an amide group, and a layered clay mineral that is organically modified by means of an organic onium salt. As a result, a polylactic acid composite material that has a sufficiently rapid crystallization rate, and that is superior in terms of heat resistance, moldability and mold release characteristics can be obtained.
