In this work, an automated dissolution system (dissoBOT) was used for testing the first time. Carry-over (CO) of dissoBOT determined paracetamol (PA) and diclofenac sodium (DS), which are active pharmaceutical ingredients (APIs). Initially, partial method validation UV-VIS spectrophotometry PA DS determination performed by defining limit detection (LOD), quantification (LOQ), linear concentration range, accuracy, precision. The LODs LOQs were less than 0.01 mg/L both APIs. ranges from 1.00 to 30.00 0.50 3.50 (the square correlation coefficient greater 0.9990, quality % APIs). accuracy evaluated calculating recovery (Re) solutions standards with known concentrations.

Bangladesh produces massive amounts of plastic products to meet the huge population demand. Jashore (Bangladesh) is well-known for discarding numbers caps (PCs). PCs are made up hard polymer polypropylene (PP) and high-density polyethylene (HDPE). was chosen as study area because quantities produced here rope (PR) prepared using PCs. About 70 % came from drinking items, 20 toiletries 7 kitchen rest 3 unidentified sectors. 44.0 were blue, 35.0 red, 11.0 green, 5.0 yellow, 3.0 white, 2.0 ash color. 52 prone damage, 26.0 discolored, 15.0 slightly damaged, about 7.0 intake. Additionally, different types ropes (ash color; red yellow color, white blue rasmi, nylon, cotton, jute, polyester rope) collected some mechanical characterization performed determine their sustainability. The internal structure ash, color PC rope, silk, cotton did not have any structural deformation, but showed a wide range deformation. Tensile strength (TS) determined Universal Testing Machine (UTM), Scanning Electron Microscopy (SEM), chemical Fourier Transform Infrared Spectroscopy (FTIR). characteristics PR compared with other ropes. highest in silky (5315 Mpa) nylon (2461.5) FTIR results that C[bond, double bond]O stretching 1800 cm

Plastic pollution has become one of the top issues at present throughout world. In Asian continent plastic is found highest rate and Bangladesh ranking as 10th number wastes producer. To minimize its management necessary. do that we tried to convert alternative resources for example tiles or tobs. The study was conducted Jashore University Science Technology campus where polyethylene are available. this research, two experiments were conducted. First preparation second making could be used in rare rural area tobs decorative purposes. find out characteristics them, compressive strength, SEM, FTIR EDX done determine durability. From results, satisfactory output product resources.

Plastic waste has started to be incorporated within construction systems with potential benefits including improved sustainability, decreased costs, lighter units and enhanced thermal performance. However, the addition of plastics an unknown impact on fire response associated behaviour recycled products. Hence, this work seeks answer question: does incorporation plastic in masonry influence risk? This study investigates effect using RESIN8 eco-aggregate bricks, aggregate based processed plastic. is done by exposing concrete bricks containing 0%, 5%, 10%, 20%, 30%, 40% 50% volume a heat flux 30 kW/m2 for hour. The replacement content samples influenced both smoke production mass loss rates, high volumes observed highest RESIN8. capacity brick was also found drop up 34.7% original compressive strength. It shown that low rates (e.g. 5 10%) are unlikely affect risk significantly, but higher may concern due release rates.

Since last few years the world is facing tremendous surge in use of surgical masks due to COVID19 pandemic. The uncontrolled disposal environment will pose serious threat living organisms plastic pollution. On other hand, construction industry hugely dependent on natural resources, leading increase carbon footprint. Therefore, it necessary investigate novel materials with sustainability perspective. In present study, alkali-activated bricks were synthesized rice husk ash (RHA), ground granulated blast furnace slag (GGBFS), sand, and sodium silicate (SS). To this, processed (PSM) added varying doses 0%, 1%, 2%, 3%, 4% by volume mix. results revealed that addition PSM significantly improved strength properties a maximum compressive 6.85 MPa at inclusion PSM. At same time, has reduced density minimum value 1.54 g/cm3 incorporation slightly increased water absorption porosity bricks, 4.76% 7.75% for PSM, when compared 0% respectively. accelerated ageing test showed after three cycles wetting drying exhibited loss range 55.2% 58.6%. microstructure bridging effect fibrous mask particles improving load transfer polymer matrix, thereby reducing brittle tensile failure bricks. pushover analysis benefit performance infill walls improvement brick reduction its self-weight, therefore, can be considered as potential material buildings seismically vulnerable areas.

Municipal solid waste (MSW) is a growing problem worldwide, as populations increase, and consumption patterns change. It not only causes pollution health hazards, but it also results in the depletion of resources. Considering this, utilization MSW sustainable construction materials has become critical area research. The purpose this review study to explore various ways which can be utilized such fired clay bricks, eco-cement, geo-polymer, fly ash (FA), bottom (BA), ceramic municipal incineration (MSWI), (IBA), coal (CBA). This article helps understand properties waste-based potential for their use applications. information renders sector design develop standard guidelines materials. significance lies its transform into more resource efficient by leveraging resources that are already available. Integrating averts from landfills incinerators, facilitates necessity raw consequently sustains natural Additionally, building lead reduction carbon trace industry, often have lower embodied energy compared traditional outcomes will provide valuable insights contribute development effective Solid Waste Management (MSWM) strategies.
