“…Another compound formed in high proportion was benzofuran, higher than 4% wt in slow and fast pyrolysis at 530 °C and 560 °C. All these compounds have been identified as high value derivative from lignin for further uses in the industry to produce biopolymers, foams, or other biobased chemicals [57,58].…”

A total of 120,000 tonnes per year of crop waste from contaminated land has been used as a feedstock for anaerobic digestion (AD). This produces only around 20% of biogas from the total crop and results in a large amount of digestate with heavy metal content. This crop digestate was analyzed across a calendar year to identify the variation in composition, and any potential high-value components that could be targeted for recovery. The chemical characterization revealed that approximately 65% of this residual waste is lignocellulosic material (20% hemicellulose, 24% cellulose, 24% lignin) and about 10% is ash, with no observable difference across the seasons. Three different pyrolysis technologies were studied with the same crop digestate as alternative route to maximize the value of this solid residue by transforming this lignocellulosic material into further bio-based products. Slow pyrolysis at operating temperatures between 355 and 530 °C resulted in bio-oil yields of 35–46% wt, fast pyrolysis at 460–560 °C produced 36–40% wt, and microwave pyrolysis using a power input of 500 and 700 W generated 8–27% wt from the digestate. Chemical compounds found in these bio-oils were categorized into seven chemical groups: acids, aldehydes and ketones, alcohols, furans, sugars, phenolics, and others. This analytical study opens other scenarios to explore the upgrading of these pyrolytic bio-oils for green product generation from the same waste. Graphical Abstract

“…5, the pyrolysis process has preserved the porous structure of the wood, opening up a range of possible applications, such as acidic catalyst or activated carbon. 45,46 The bitumen industry has seen a growing interest for bio-oil applications in recent years, 13,14,[47][48][49] driven by increasing costs of raw petroleum-based materials and by the decreasing share of bitumen coming from more and more efficient petroleum refineries.…”

Forest biomass is an attractive alternative resource to fossil ones, renewable and without environmental impacts as long as forest residues are considered. Collecting and transforming forestry residues into value-added products is a challenge as they are usually scattered over a large area. To reduce the economic and environmental cost of forestry residues transformation, in-situ energy densification is a powerful solution. To achieve efficient energy densification of forestry residues and transformation for industrial use, a new pyrolysis unit designed by the University of Western Ontario is used to produce low water content pyrolysis oil and high-quality biochar. Bio-oil with 8 %wt water content is produced. Energy density of the bio-oil is compared to other densification methods, showing the interest of pyrolysis to increase the energy density of biomass. High quality and free of sand biochar is also produced. Various properties of the bio-oil and biochar are explored to determine its potential for various industrial applications in the scope of a major biorefinery project in La Tuque, Québec.

A lot of water waste streams are produced during the production of hardboard panels. This paper analyses the feasibility of using a lignin-containing waste from the hardboard industry in asphalt binders. It would contribute to both waste reduction and decrease of the consumption of asphalt in order to obtain environmental, economic and social benefits. The waste from the hardboard industry was not subjected to any transformation i.e. it was blended directly with the conventional asphalt. Asphalt binder samples blended with 0, 5, 10, 20 and 40% of the waste were aged in a rolling thin-film oven apparatus. Basic characterisation (penetration grade, ring and ball softening point and resilience) as well as advanced characterisation (dynamic viscosity, shear complex modulus and phase angle) were performed. Asphalt binders blended with up to 20% waste can be stored, pumped and handled at hot-mix asphalt facilities. Addition of the waste to asphalt binder increases the viscosity and the shear complex modulus and reduces the phase angle. The waste produces asphalt binders with higher storage modulus and lower loss tangent. The waste enhances fatigue and rutting resistance. Asphalt binder with 20% of waste displays the best potential for use as an extender and as well as an enhancer in asphalt pavements. The research results can offer technical support to value this waste from hardboard production, without the need for subsequent transformations.
