“…Finely-dispersed waste from the spinning of plant annuals is formed after chemical treatment of raw materials at the stage preceding fiber spinning and subsequent repeated mechanical exposures. At the same time, the cellulose polymerization degree of materials decreases [32,36], the mobility of cellulose macromolecules increases and hydroxyls are activated on the microfibril surface, which leads to an increase in the material intermolecular hydrogen bonds [33].…”

Wood processing soft waste is mainly used in the production of fuel briquettes, irrecoverable (non-recyclable) waste from spinning flax and cotton are incinerated or sent to dump. The development of methods for recycling non-recyclable cellulosic waste through the product manufacturing is relevant, both from the resource conservation perspective, as well as the environmental point of view. The issues of plant waste recycling through the manufacturing of various types of products are widely developed in the Russian and foreign scientific research practice. Researchers deal with the processing of wheat, rice straw, bamboo stalks, and other cellulosic materials. There is a plenty of published information on methods of soft wood waste recycling. However, no research on recycling irrecoverable waste of spinning flax and cotton fibers had been carried out before this paper. We propose to produce thermal insulation boards based on phenol-formaldehyde resol binder using flax and cotton spinning waste and soft wood processing waste. The wet production method used here involves mixing the filler with water, a precipitant solution and a binder. After spinning the material is dried. The paper presents the results of determining the physical and mechanical properties and thermal conductivity coefficient of boards made of plant waste. The research was carried out according to the B-plan of the second order. Adequate regression mathematical models of the dependences of physical and mechanical parameters of the boards on the varying factors of the production process were developed according to the experimental data processing results. Using the developed regression models we built the response surfaces of the composite parameters: the bending strength of the boards, the thickness swelling of the boards after 24 h of exposure in water and the thermal conductivity coefficient. Nomograms of the dependencies of board parameters on the values of varying factors have been developed based on the mathematical models analysis. The nomograms are the basis for the development of practical recommendations for determining the rational values of the parameters of insulation board materials production from irrecoverable waste of spinning flax and cotton and soft wood processing waste.

“…Examining previous studies, it has been proven that textilereinforced polymeric-based composite materials can be used in construction and building applications [3,10]. These studies mainly focus on the use of recycled textile wastes of synthetic fibers such as polyester [11,12] and natural fibers like wool, cotton, and flax [13][14][15] as a reinforcement/filling material in composite structures. On the other hand, thermal insulation property of composite materials consisting of both recycled textile material and thermoplastic resin was rarely studied [16].…”

Considering the risks facing nature today, the search for sustainable materials has become a necessity. The polyethylene, which is the main waste of the packaging sector, and the cotton fibers, which are among the leading wastes of the textile industry, are increasing day by day and the recycling these wastes by using them as reinforcement materials in composites emerges as a sustainable solution. In this study, 100% recycled composite materials are designed according to the different numbers and sequences of recycled cotton fiber layers and recycled polyethylene matrix plates and produced by hot press method. The physical and thermal properties of the samples are tested to evaluate their usability as a sustainable insulation panel.

Soft wood waste is mainly used for fuel purposes. Non-returnable vegetable spinning waste is currently not used in the production of products, disposed of by incineration or disposal to landfill. Emissions of carbon-containing gases are the dominant source of anthropogenic emissions into the atmosphere, which leads to disruption of the natural carbon cycle. The aim of the study is to develop a method for recycling waste spinning flax and cotton fibers and soft wood waste by producing composite thermal insulation material. Physical and mechanical parameters and thermal conductivity coefficient of composites are determined.
