“…Fixed carbon tests resulted in a range of 11.00 to 17.19%, also reported in the literature for other wood biomasses, between 12 to 26% (Vega et al, 2019). Species like Cenostigma pluviosum are highly reactive biomass in consequence of high VM and low FC content that results in quicker burning (Jahirul et al, 2012;Vassilev et al, 2015;Vega et al, 2019).…”

“…The values ranged from 77.52 to 87.56% of volatile materials and the ash content from 0.48 to 5.29%. Since the volatile material content influences the rate at which fuel becomes gas, woods with higher VM content can generate more steam, promoted by the devolatilization reactions (Vassilev et al, 2015;Vega et al, 2019). Fixed carbon tests resulted in a range of 11.00 to 17.19%, also reported in the literature for other wood biomasses, between 12 to 26% (Vega et al, 2019).…”

Urban tropical forest species generate large amounts of wood waste by pruning and removing urban trees, which can be an accessible source of biomass that could be used to generate energy instead of being disposed of irregularly. The objective of this study was to evaluate the potential for energy production of the wood residue of seven species most used in urban forestry in the State of São Paulo, Brazil, by determining the physical, chemical and energetic characteristics. Wood waste of 7 common urban forests species in the State of São Paulo were collected in the city of Piracicaba, characterized (humidity, basic density and bulk density), chemically (extract content, volatile materials, fixed carbon and ash content) and energetically (higher, lower, useful calorific power, density energy and thermogravimetric analysis). The highest value of basic density was found in the species Cenostigma pluviosum (653.76 kg/m³), all species had higher calorific values greater than 19 MJ/kg and the energy density of the species varied between 4.45 to 10,80 GJ/m³. The use of these wood residues for direct combustion is a viable alternative and can be considered as a solution to replace the incorrect disposal, which is still a common practice in many cities in developing countries.

“…On the other hand, the lumber industry generates a considerable amount of waste that includes leaves, barks, sawdust, chips, cones, resins, and branches. These residues are not usually well valued and are thrown out, burned, or used for animal bedding, although they can be a profitable source of high added-value compounds [30]. Therein, wood biomass residues increase their overall value due to the metabolites that are present in lower abundance compared with cellulose, hemicellulose, and lignin.…”

Green and Sustainable Valorization of Bioactive Phenolic Compounds from Pinus By-Products

In Europe, pine forests are one of the most extended forests formations, making pine residues and by-products an important source of compounds with high industrial interest as well as for bioenergy production. Moreover, the valorization of lumber industry residues is desirable from a circular economy perspective. Different extraction methods and solvents have been used, resulting in extracts with different constituents and consequently with different bioactivities. Recently, emerging and green technologies as ultrasounds, microwaves, supercritical fluids, pressurized liquids, and electric fields have appeared as promising tools for bioactive compounds extraction in alignment with the Green Chemistry principles. Pine extracts have attracted the researchers’ attention because of the positive bioproperties, such as anti-inflammatory, antimicrobial, anti-neurodegenerative, antitumoral, cardioprotective, etc., and potential industrial applications as functional foods, food additives as preservatives, nutraceuticals, pharmaceuticals, and cosmetics. Phenolic compounds are responsible for many of these bioactivities. However, there is not much information in the literature about the individual phenolic compounds of extracts from the pine species. The present review is about the reutilization of residues and by-products from the pine species, using ecofriendly technologies to obtain added-value bioactive compounds for industrial applications.

“…Recently, there has been growing attention in the vision for environmental-oriented manufacturing and the concern that wastes should be converted into wealth [1][2][3][4]. In automobile engineering in developing countries, the general practice is to dispose of out-of-use engine blocks and parts and such practices often lead to environmental pollution due to the reactions of the metallic parts with soils in the long-run, and the contamination of soils with engine oil remnants from the engine blocks [5].…”

The A356 alloy is widely known to exhibit an extremely superior casting, machining, mechanical, and corrosion resistance properties. Despite these, it constitutes an environmental nuisance at its improper disposal for worn-out engine blocks. Also, organic reinforcements have the potentials to reduce the environmental impacts of composites. Consequently, there exits significant research potential to fuse A356 alloy with organic materials to obtain enhanced composite properties. In the area of aluminium matrix, as melting and solidifications of materials are done the accuracy of measurements is driven by the huge array of process parameters and the geometrical aspect of cast components is important. For these reasons, we attempt to solve the problem of optimising the geometry of casts in a complicated scenario with the use of the robust Taguchi's methods. To optimise the framework, the significant process parameters are identified and their effects studied in a route using Taguchi, Taguchi-Pareto and Taguchi–ABC methods. Parameters such as the volume of the cast, length, weight, density, height, width, breadth, weight loss and the total weight of organic materials infused into the melting process were studied for parametric changes, interactions and optimisation with L27 orthogonal array. The analysis of variance for the A356 alloy cast revealed that the density parameter of cast 1 had the highest and major significant effect on the casting process with a variance of 333573, followed by weight parameter of casts 1 and 2, total weight of organic material parameters and weight loss with the variance values of 0.007, 0.005, 0.001 and 0.004, respectively. The variance of other parameters was insignificant to the A356 alloy cast.
