Industrial Waste Management to Improve Environmental Quality
By Reinaldo Ragil Rompas

Industrial waste can harm the environment. To avoid environmental pollution, industries must now understand how to manage industrial waste. Every company must accept responsibility for the waste it produces. Mishandling of waste from industries will pollute the environment.
While factories and industrial waste are not properly managed, they pollute the air, water, and soil. If waste is only dumped at a landfill, it will eventually produce methane gas. If methane gas levels rise, it will contribute to global warming via the greenhouse effect.

Waste is a major problem that affects almost every country. The quantity of waste will go up over time. Waste issues arise in a variety of sectors, particularly in industry. Industrial waste is a problem that industry users and the government must address because it can pose a variety of risks and environmental damage to living creatures if not properly managed. Waste from industries is debris or waste that results from industrial activities. In simple terms, industrial waste is the waste generated during industrial production activities. Waste is generated in various forms according to the industrial goods that are produced. A good instance would be the textile industry. The textile industry generates waste in the way of food scraps, as well as waste from textile dyes.

As manufacturing industries develop, the waste that is produced becomes more diverse. Industrial waste is divided into four categories: liquid waste, solid waste, gas waste, and hazardous and toxic (B3) waste.

  • Liquid Waste

As the name implies, liquid waste generated during industrial production processes. This waste is typically dumped into sewers, rivers, and even the ocean. Liquid waste composition varies with industrial production. Liquid industrial waste is divided into two types: liquid industrial waste that is capable of being neutralized rapidly and liquid industrial waste which contains hazardous materials. The disposal of hazardous liquid waste with no processing can pollute water, harm the ecosystem, and cause death to the organisms that exist over there. Liquid industrial waste includes fermented of soybean waste, tofu waste, food and clothing coloring residues, preservative solution residues, water used for washing from production materials, iron in water, and other chemical residues.

  • Solid Waste

Solid waste is produced through the handling or removal of waste coming from industrial activities as well as public places. Solid waste from industry can be both organic and inorganic. Solid waste refers to waste that remains as a result of industrial activities, including sludge and fertilizer as well as production waste that is solid. Solid waste threw underwater may pollute the water, causing damage or destruction to the ecosystem. Furthermore, dumping solid waste on land without previous handling pollutes the local environment. Solid industrial waste includes apparel waste, plastic waste, chips of wood, paper pulp residue, cables, slurry from cement residue, iron, and so on.

  • Gas Waste

Waste of gas is a byproduct of industrial processes in shape of gas molecules. Gas molecules that surpass the standard are considered waste. If not precisely handled, this trash pollutes the air and harms living organisms. Industrial gases include gas leaks, manufacturing smoke, combustion, excess methane gas, carbon monoxide, and hydrogen peroxide.

  • Hazardous and Toxic (B3) Waste

Hazardous waste (B3) represents a form of industrial waste containing hazardous and poisonous substances. B3 waste contains a significant number of harmful compounds and needs to be handled individually. The careless or inadvertent disposal of B3 waste pollutes the environment, damages it, and threatens the creature living health. Lubricant processing, cement processing, paper pulp processing, and pharmaceutical manufacturing are all examples of industries that generate B3 waste.

Waste management is a method that frequently gets carried by the industries such as the waste that gets disposed of has changed in character, like hazardous waste into non-hazardous trash, after being processed utilizing regularly used steps, such as:

  • Physically: Industrial waste can be managed physically; however, this strategy has little effect on chemical behavior. Waste is treated to alter its size, shape, or condition. The process involves carbon absorption, distillery, filtering, evaporation, milling, and compression. 
  • Chemically: Chemical waste processing involves modifying the composition or character of the waste with chemicals. So, a reaction will take place in the garbage. The inclusion of these chemicals is intended to remove particulates, metals, and hazardous organic substances from waste. Various procedures include neutralization, oxidation and reduction, deposition, acid wash, ion exchange, incineration, and thermal desorption. 

Biologically: Biological processing of waste is a waste handling method that uses other living things to break down the organic components in garbage. The additional microbes will decompose the waste. The procedures utilized are aerobic and anaerobic organisms. 

One measure that industries may take to mitigate waste pollution is to reduce the sources of trash generated during the production or manufacturing process. Many organizations have implemented waste-reduction techniques, including technology modifications, the creation of structured facilities, the restructuring of industrial processes, and anaerobic organisms. 

In Conclusion, effective industrial waste management is a shared duty among industry, government, and society. With executing proper plan, a sustainable industry and environment quality are improving along with time.
