Industrial Wastes And Current Recycling Methods: Are They Enough?

Industrial waste is the byproduct of effluent produced because of any industrial activity comprising any material appraise futile during the mechanized process of factories, mills, mining operations, and industries. Most of the time, countries mix industrial waste with municipal wastes, which makes the accurate count ambiguous. However, an average estimate of US industrial waste piles up to 7.6 billion tons per year. 

Types of Industrial Wastes

  • Water Waste
  • Solid Waste

Industrial Waste: Water Waste

They need an enormous quantity of water for the industries to run gigantic machines and manufacture the artifact.  Wastewater from industries may include the extra or surplus water that remains after the melting out of manufactured goods.

Resources of Waste Water

There are various resources of the waste water from different industrial niches. Some of them include:

  • Iron and steel Industry
  • Pulp and Paper Industry
  • Milk and Dairy Industry 
  • Brewing Industry
  • Mines Industry
  • Food Industry
  • Chemical Industry
  • Nuclear Industry
  • Water Waste Treatment of Industries

They did treatment of wastewater to restore it into drinkable form, which requires a separate procedure. Most of the industries really need to treat the water properly to attain a patronizing quality of water for demanding purposes.

The wastewater contains oil, grease, dirt, solid matter, organic and inorganic wastes, biodegradable wastes, alkali and acids and other toxic matter. Exclusion of all these wastes entails stepwise procedures separately for each kind of waste matter. 

Initial treatment of waste water produces plenty of organic and mineral sludge because of Filtration and Sedimentation processes. 

Further, Ion Exchange chromatography removes ions such as calcium, magnesium and carbonates ions and replaces them with hydrogen and hydroxyl ions of water.

Industrial Waste: Solid Waste 

The solid waste refers to any unwanted or surplus matter that has served its purpose and is idle because it’s no longer of any use to the industry. The solid waste is neither liquid nor gas. 

There are several forms of solid wastes dissolved with water wastes most of the time.

Resources of Solid Waste 

  • Construction and demolition wastes,  
  • Biodegradable waste from the food industry. 
  • Non-biodegradable waste such as polythene bags, scrap material, glass bottles.
  • Recyclable waste such as paper, plastic, glass.
  • Non-recyclable waste including wastes from packaging material.
  • Hazardous waste, is highly toxic, such as e-waste, lead batteries.
  • Non-hazardous waste is of an ordinary nature, such as organic waste.
  • Solid Waste Treatment of Industries.

The treatment of the solid waste is indispensable to avoid the excessive accumulation of wastes on ground and in water which would definitely result in pollution. Once collected, it would take the solid waste care of in a way so as to reduce the total volume and weight of the solid waste. Treatment of solid waste makes the process easier. With the help of treatment, the wastes help recover useful or recyclable materials which can be utilized to produce heat energy. The current strategies to treat solid waste include:

Reduce, Reuse, and Recycle of Solid Waste Treatment 

Three R’s are in practice for the solid waste management i.e. 

Reduce means to minimize the waste production to the best level possible at industrial and commercial level.

Reuse means to use the items more than once, which will cause saving time, energy, money and resources.

Recycle means to change the waste products into something useful to make it available for use.

Biological Waste Treatment

It refers to the treatment of solid wastes using biological reactions. For instance, it decomposes the organic matter to form Compost by the process called Composting. They do this kind of treatment for the waste of the food industry.

Thermal Waste Treatment

By using thermal treatment for the solid waste management, the waste is being burnt at high temperature in an incineration furnace where it is turned back into ashes. Thermal treatment may include:

  • Incineration
  • Pyrolysis
  • Plasma Gasification
  • Chemical Treatment of Solid Waste

This process includes the chemical DE polymerization of the removal of matrix with the help of chemical dissolution of fibers. This chemical treatment can be useful in regenerating the spotless fiber and fillers.

Bottom-line

Over the globe, every country has enacted particular laws and legislations to deal with the problem of industrial waste treatment issues, its harmful environmental effects and its safe disposal methods, however; ways of implementation. The wastes of treatment and recycling methods in use are pretty much magnificent efforts to further betterment, but still we need to revise our dumping practices. 

Most of the industries still dump their water and solid wastes into the water or landfills improperly, which is a huge cause of various kinds of diseases and aids the pollution. Burning matter harnesses harmful gases while dangerous chemicals from chemical or nuclear industry are not only harmful for aquatic life but also damaging human health seriously.

The current issue is to establish a market for recyclers, as this industry is still flourishing. The biggest challenge for the recycling of compost material is the insufficient end-user for recycled material.  The overall cost of the recycling of any material is much higher than the actual price of waste matter itself, which makes it almost impossible for business in the market.  For these recycling methods to work in the market, I think they should consider new strategies.

  • Ways to find low cost and efficient recycling procedures.
  • The environmental parameter on incineration and landfills of compound material. 
  • The profit and sustainability of the recycling business should get revise according to the current market.
  • The overall cost and environmental boundaries and the outcome of the recycled product cost.
