TL;DR: The analysis suggests that biomass waste pyrolysis processes can be divided into three zones, proceeding from a heat-transfer dominant zone (zone 1) to catalysis dominant zones (zones 2 and 3) and the indexes conducted in the present study can provide useful measures to identify the catalytic pyroglysis dynamics and levels.

TL;DR: The Madhabdi municipality in the Narsingdi district of Bangladesh is a well-known area for textile, handloom weaving, and dyeing industries, and the concentrations of Fe, Cr, Cu, Pb, and Mn exceed the industrial effluent discharge standards (IEDS) for inland surface water and irrigation water guideline values.
Abstract: The Madhabdi municipality in the Narsingdi district of Bangladesh is a well-known area for textile, handloom weaving, and dyeing industries. These textile industries produce a considerable amount of effluents, sewage sludge, and solid waste materials every day that they directly discharge into surrounding water bodies and agricultural fields. This disposal poses a serious threat to the overall epidemic and socio-economic pattern of the locality. This research entailed the collection of 34 handloom-dyeing effluent samples from different handloom-dyeing industries of Madhabdi, which were then analyzed to determine the contents of the heavy metals iron (Fe), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), lead (Pb), and cadmium (Cd). Average concentrations of Fe, Cr, Cu, Pb, Mn, and Zn were 3.81, 1.35, 1.70, 0.17, 0.75, and 0.73 mg L-1, respectively, whereas Cd content was below the detectable limit of the atomic adsorption spectrophotometer. The concentrations of Fe, Cr, Cu, Pb, and Mn exceed the industrial effluent discharge standards (IEDS) for inland surface water and irrigation water guideline values. A biosorption experiment of the heavy metals (Fe, Cr, Cu, Mn, and Zn) was conducted without controlling for any experimental parameters (e.g., pH, temperature, or other compounds present in the effluent samples) by using four agricultural wastes or byproducts, namely rice husk, sawdust, lemon peel, and eggshell. Twenty grams of each biosorbent was added to 1 L of effluent samples and stored for 7 days. The biosorption capacity of each biosorbent is ranked as follows: eggshell, sawdust, rice husk, and lemon peel. Furthermore, the biosorption affinity of each metal ion was found in the following order: Cu and Cr (both had similar biosorption affinity), Zn, Fe, Mn. The effluents should not be discharged before treatment, and efficient treatment of effluents is possible with eggshell powder or sawdust at a rate of 20 g of biosorbent per liter of effluents.

TL;DR: In this paper, the reproducibility of testing formaldehyde and VOCs (volatile organic compounds) emissions from wood-based composites such as MDF (medium density fiberboard), hardboard, plywood, coated and raw particleboards, planed pine lumber, and gypsum board was assessed.
Abstract: This paper assesses the reproducibility of testing formaldehyde and VOCs (volatile organic compounds) emissions from wood-based composites such as MDF (medium density fiberboard), hardboard, plywood, coated and raw particleboards, planed pine lumber, and gypsum board. Sawdust and shavings were also included in the study. With the help of a special device, air was sucked from the surfaces of the materials and then was adsorbed on charcoal and Tenax tubes. The adsorbed VOCs were determined by gas chromatography/mass spectrometry. The emission of formaldehyde was determined separately with Interscan Toxic Gas analyzer and chamber method. The results showed that the most emitted VOCs were terpenes, aldehydes, and aromatics. Pine wood plank revealed the highest VOCs (approximately 900 μg/m3). Fresh particleboard showed the second highest value with 450 μg/m3. The VOC value of other examined materials were 80–170 μg/m3. The composition of the emitted compounds was remarkably similar among the different materials. The low VOC emission from the board materials investigated did not verify the hypothesis that these materials provided a tangible contribution to VOCs in the indoor air. Emission of formaldehyde from the board materials studied was very low with an exception. The exception was MDF with an emission value of 0.63 mg/m3 formaldehyde whereas all the other materials examined had values around 0.05 mg/m3 or appreciably lower.
