The odour emitted from wastewater treatment plants is a big concern due to air pollution. These odours are mainly caused by pungent gases from the wastewater facilities, leading to significant health issues, nuisance in public, and no compliance with the environmental laws. Many industries release pungent gas that is very much corrosive and can hurt the life of the equipment, quality of life, and productivity. A foul odour can have negative impacts on businesses and lead to negative publicity, thereby resulting in the breaking down of company as well as community relations. This has made odour control in wastewater treatment a significant requirement. Wastewater odour control units are crafted for reducing the release of odorous gas such as hydrogen sulphide organic Sulphur compounds along with volatile organic compounds to a permissible limit. It also effectively eliminates pollutants and odours from the air jammed by the industrial and manufacturing processes. Starting from

  VOC or Volatile organic compounds are emitted in significant quantities from different furniture units coated with paint coating, solvents, varnishes, and waxes. It has been seen that furniture units made from solid wood and wood composites play a significant role in the emission of VOC. They have an adverse effect on the human body and are directly related to several health risks. In simple words, VOCs are lipid-soluble compounds that can easily pass through the blood-brain barrier resulting in neurologically adverse health impacts. While several new technological developments in furniture finishing have resulted in stylish furniture units, it is a real fact that they can lead to indoor air pollution. All designers, producers, and consumers are much concerned about furniture products' aesthetics, cost, durability, and functionality. But the issue regarding chronic VOC exposure from furniture must be addressed. Mainly solid wood and wood panels are used for manufacturing fu
