“…the fuel/air interface was distinct. In contrast, the (non-pelletized) MS straw used in our study had low density and high porosity, thus providing optimal oxygen supply during combustion, which in turn further promotes more complete combustion (Daragon et al, 2014). Consequently, the combustion conditions in the study of Kasurinen et al (2015b) were very different to those used in our experiments; the resulting emissions and their observed toxicity also differed in the two studies.…”

Inhalation of particulate matter (PM) from residential biomass combustion is epidemiologically associated with cardiovascular and pulmonary diseases. This study investigates PM0.4–1 emissions from combustion of commercial Miscanthus straw (MS), softwood chips (SWC) and beech wood chips (BWC) in a domestic-scale boiler (40 kW). The PM0.4–1 emitted during combustion of the MS, SWC and BWC were characterized by ICP-MS/OES, XRD, SEM, TEM, and DLS. Cytotoxicity and genotoxicity in human alveolar epithelial A549 and human bronchial epithelial BEAS-2B cells were assessed by the WST-1 assay and the DNA-Alkaline Unwinding Assay (DAUA). PM0.4–1 uptake/translocation in cells was investigated with a new method developed using a confocal reflection microscope. SWC and BWC had a inherently higher residual water content than MS. The PM0.4–1 emitted during combustion of SWC and BWC exhibited higher levels of Polycyclic Aromatic Hydrocarbons (PAHs), a greater variety of mineral species and a higher heavy metal content than PM0.4–1 from MS combustion. Exposure to PM0.4–1 from combustion of SWC and BWC induced cytotoxic and genotoxic effects in human alveolar and bronchial cells, whereby the strongest effect was observed for BWC and was comparable to that caused by diesel PM (SRM 2 975), In contrast, PM0.4–1 from MS combustion did not induce cellular responses in the studied lung cells. A high PAH content in PM emissions seems to be a reliable chemical marker of both combustion efficiency and particle toxicity. Residual biomass water content strongly affects particulate emissions and their toxic potential. Therefore, to minimize the harmful effects of fine PM on health, improvement of combustion efficiency (aiming to reduce the presence of incomplete combustion products bound to PM) and application of fly ash capture technology, as well as use of novel biomass fuels like Miscanthus straw is recommended.

“…Despite adsorbents or chemicals used in conventional treatment (absorption and extraction) are cheaper than advanced treatments, both show high efficiencies (Villegas et al 2016). It is even possible to reduce costs further with the use of low-cost adsorption media (Daragon et al 2014). Table 4 shows that certain wastewater types can have high lignin content, such as wheat straw and kraft pulping effluent.…”

Pests have a negative impact on the economy and the environment. There is an increased urgency for adequate pest control because many pests show high adaptation and climate change has created favorable circumstances for pests. For pest control, synthetic chemicals are used that are lethal to non-target organisms and are toxic to pollinators and aquatic invertebrates. Chemical compounds in plants and derivatives from lignocellulosic materials act against pests. The wastewater from lignocellulosic biomass is a potential source of new compounds with bactericidal, fungicidal, and pesticidal effects that have demonstrated inhibitory activity against plant pathogens. Fungicidal, nematicidal, insecticidal, larvicidal, and bactericidal activities have been proven. Inorganic and organic compounds, such as phenols, aldehydes, esters, and furanics, are the main ones identified. Due to the antimicrobial activity of wastewater, applying it to the soil can modify the composition and structure of key microbial communities. Deep research about richness, biodiversity, functionality, and microbials is needed. This review provides a comprehensive overview of wastewater types that have been applied and possible sources to obtain potential compounds for pest control. Moreover, associated active compounds, recovery techniques, and environmental impacts are reviewed.

Vinasse is one of the most polluting e uents in the sugar-alcohol industry due to its physicochemical properties. It poses a threat to soil fertility and can contaminate groundwater if not appropriately handled. Therefore, it is important to evaluate more sustainable and comprehensive vinasse treatment strategies to safeguard environmental integrity. So, this work aims to evaluate sugarcane bagasse and peanut shell, as renewable adsorbents, for the removal of organic matter, pH, and turbidity found in vinasse e uent. Commercial activated carbon was used to compare the performances. Experimental assays were conducted using the adsorbents under three different concentrations (1: 12.5 g L -1 ; 2: 25.0 g L -1 ; 3: 37.5 g L -1 ) at 3, 6, 12, 24, and 48 hours of treatment, under controlled temperature (25°C) and rotation (200 rpm).The bioadsorbents were able to promote marked removal of organic matter, showing natural adsorbent properties without any previous activation. Major COD removal (63.88%) was observed for the commercial activated carbon after 48 hours of treatment and a concentration of 37.5 g L -1 . For the peanut shell and sugarcane bagasse, the major COD removal was 50.94% and 45.35%, respectively, after 48 hours of treatment and a concentration of 12.5 g L -1 . The nal e uent exhibited high residual COD content, indicating the necessity to associate with another treatment state, such as biodigestion or ozonolysis, acting as a pretreatment or as a posttreatment.
