“…Many other studies have addressed the topic of liquid wood [27][28][29]. These are pure biopolymers, such as lignin (e.g., Arboform), or hybrid mixtures with other biocompatible waste, and they use specific characteristic injection modelling in an almost liquid form due to thermal processing [17,27].…”

Waste has become an everyday subject, especially its efficient recycling due to the increasing decline in the planet’s primary resources. Therefore, their recovery is intended to be total and with minimal energy consumption. Biomass waste is fully recoverable in raw or processed states and in combination with other compatible waste types (including wastewater from construction, polymers, and sunflower seeds). It represents the basic elements for obtaining synthetic wood to replace natural wood, which is very expensive and difficult to obtain (lasts for several years). This paper proposes three methods to determine the thermal conductivity of these new materials (synthetic wood) to guarantee and optimise their thermal characteristics. The determination of thermal characteristics in insulating materials is usually performed experimentally in a double climate chamber or more simply using a special instrument of the ISOMET type, but under these conditions, the sample must meet certain conditions imposed by the manufacturer to be tested. Thus, two experimental investigation methods are used to which a numerical method is added, which consists of modelling by the finite element method with an adequate programme of heat transfer through these materials. Four samples with variable content of recyclable waste obtained through combinations resulting from six different experimental design plans with two controlled factors were analysed to optimise synthetic wood recipes for the efficiency of their hygro-thermal characteristics. The content of the tested samples varied relative to the quantity and number of recyclable wastes included in the final recipe. Thus, the thermal conductivity obtained was different for each sample but close to that of similar synthetic wood-type materials and natural wood.

“…In order to make the overall process economically feasible, a sustainable utilization of all biomass constituents is considered to be essential. Especially the lignin fraction poses a promising product which could be applied in thermoplastic polymers and composites 5, highly porous materials like aerogels 6 or for the production of phenolic compounds 7. However, the obtained biorefinery products like pentose‐derived chemicals or lignin do not yet fulfill the requirements of potential industrial or private users.…”

In this work a process for the production of odor‐free lignin from wheat straw using solely water, enzymes and CO2 is described. Wheat straw pellets are pretreated by liquid hot water and enzymatic hydrolysis in a pilot plant with a capacity of 40 L, which enables the production of 3 – 4 kg of Aquasolv lignin per batch. Dried lignin samples are further treated using supercritical CO2, resulting into extraction of a large number of odorous free fatty acids and volatile organic compounds. All process steps can be sequentially conducted in a fixed‐bed via different sustainable solvents in a throughput regime.

“…Wood liquefaction is one of the several chemical processes in which wood is derivatized or degraded without a costly separation and purification prior to the reaction in which wood is converted into a multifunctional liquid. 1 The process is normally carried out at elevated temperatures with the use of reagents and catalysts that have sufficient reactivity toward wood components. Most of the reported research has been done on the use of phenol 2–4 and various polyols 5, 6 as the liquefaction reagents, most commonly in conjunction with the use of strong acids as catalysts.…”
