This study used several statistical analyses to explore the impact of both inert and oxidative conditions on characteristics biochar derived from torrefaction spent coffee grounds (SCG). The also considered variations in temperature residence time. Various fuel were conducted, including high heating value (HHV), index, proximate characteristics, thermogravimetric analysis (TGA), hygroscopicity, Fourier-transform infrared spectroscopy (FTIR). variance (ANOVA) revealed that influence HHV mass yield was insignificant (p ≥ 0.05). Moreover, considering same time, principal component (PCA) hierarchical cluster (HCA) identified belonging group or cluster. finding indicated neither atmospheric condition significantly affected measured this research. Therefore, offers significant advantages as it can produce comparable quality under conditions.

The "Great Acceleration" of the mid-20th century provides causal mechanism Anthropocene, which has been proposed as a new epoch geological time beginning in 1952 CE. Here we identify key parameters and their diagnostic palaeontological signals including rapid breakdown discrete biogeographical ranges for marine terrestrial species, changes to ecologies resulting from climate change ecological degradation, spread exotic foodstuffs beyond range, accumulation reconfigured forest materials such medium density fibreboard (MDF) all being symptoms Great Acceleration. We show: 1) how Anthropocene successions North America, South Africa, Oceania, Europe, Asia can be correlated using signatures highly invasive species that demonstrate growing interconnectivity human systems; 2) unique depositional settings landfills may concentrate remains organisms far geographical range environmental tolerance; 3) preserve long-lived, record within post-mid-20th deposits. Collectively these provide global signature is distinct past records deep-time biotic change, those Holocene.

This paper develops a novel class of timber-cardboard sandwich (TCS) panels, consisting low-cost timber facings and block-laminated corrugated cardboard core. Experimental analytical studies are conducted to characterise the flexural performance TCS beams made from recycled or waste materials. scrap cores have exceptional characteristic being mostly waste, up 91% by volume 76% weight, demonstrated equivalent with cores. beam behaviour is found be primarily governed face sheets, very strong composite action no observed core shear debonding failure. The strength, stiffness, dominant failure mode thus shown accurately predicted using theory cross-sectional analysis. bending strength also significantly higher than conventional foam-core structurally-insulated panels comparable densities, making them highly viable as bio-based structural alternative. These research findings enhance capacity confidence which can used construction feedstock, supporting societal progression toward greener more circular economy.

Composite materials are increasingly being implemented in various solutions, ranging from conventional applications, like furniture, to more advanced ones, such as aerospace, based on their excellent properties, high mechanical strength and low weight. There applications which these coupled other parts. To achieve this connection, drilling processes commonly used. Drilling causes irreversible damage the material, influences of plates. This study was conducted 48 carbon/epoxy plates, each with two drilled holes, DOE (design experiments) Taguchi method design experimental plan validate results. Three control factors were considered for drilling: drill bit type, cutting speed, feed rate, it is expected that a rate speed configuration inflicts least damage. Subsequently, specimens subjected enhanced radiography an image analysis processing tool MatLab® assess data collected compute At end, analyzing results method, possible assumptions influence process delamination extension.

Recycling is presently the most environmentally friendly approach that deals with wood waste. Each year a huge amount of particleboard completes its service life and needs to be disposed or recycled. Scrap has potential reused as raw material for production. A crucial step producing particleboards using scrap break down urea-formaldehyde (UF) resins in obtain separated particles. In this study, liquid hot water (LHW) pretreatment was employed decompose UF detach recover particles from particleboards. The recovered fresh industrial different proportions were used particleboard. physical mechanical properties recycled evaluated. modulus rupture (MOR), elasticity (MOE), internal bond (IB) lower than those made However, 2 h thickness swelling (TS) better particleboards, indicating more dimensionally stable. containing up 40% met minimum Chinese National Standard requirements general-purpose Conclusively, could utilized

The wood-based panel industry is experiencing an excessive accumulation of solid residues from the production medium-density fiberboard (MDF) panels and moldings. It possible to create new MDF products with acceptable physical mechanical properties by revaluing residues. Additionally, those products’ thermal can be improved incorporating phase change materials (PCMs). This study aims develop a made residues, capable storing energy. Two types PCMs, two PCM ratios, adhesives were used produce eight different panels. vertical density profile, thickness swelling, water absorption, internal bond (IB), static bending – modulus elasticity (MOE) rupture (MOR) determined for each type. specific heat was also determined. results show panels’ densities greater than 700 kg/m3. Thickness swelling in 23% compared reference value control PCMs after incorporation. highest IB 1.30 MPa, which almost three times minimum required regulation standards. incorporation reduced Even though values obtained are sufficient comply set out ANSI standard A208.2 MOE 2072.4 MPa standards MOR 16.4 MPa. When microencapsulated used, increased more 100% over that develops feasible alternative using residues: energy has adequate properties.
