General overview of the electroplating and anodising industry

Also known as electroplated coating and electrodeposition, electroplating uses an electric current to decrease dissolved metal cations (positively charged ions). This is doneto form a thin coherent coating on an electrode. On the other hand, anodising is an electrolytic passivation process. It is utilised to boost the thickness of the natural oxide layer over the surface of metal parts. However, the main characteristic ofthe electroplating and anodising industry is to offer a protective layer for metal products. This is doneto prevent from metal rust, corrosion etc. and boost its good characteristics.

Significant challenges faced by the electroplating and anodising industry

Though beneficial in a certain way, the electroplating operations produce emissions of hazardous air pollutants (HAPs). These pollutants includecyanide, heavy metalsand volatile organic compounds (VOCs).Also, electroplating with aluminiuminvolvesusingspecialised equipment and toxic solvents.Furthermore, it has been noted that out of the total amount of metals used in electroplating, 4% goes as waste in electroplating solutions, sludge spent wash and so on. Undoubtedly, the pollutants released through the electroplating industry are hazardous and contaminate the environment.

While on the other hand, the anodising process with a sulfuric acid bath releases two by-products: aluminium hydroxide and degraded sulfuric acid. The former is a compound of aluminium from the anodised part, oxygen and hydrogen from the acid. Categorised by the Environmental Protection Agency(EPA) as hazardous, aluminium hydroxide wastewater can’t be discharged into a municipal wastewater system. The EPA has setrigorous standards for the highest allowable aluminium concentration level upon disposal. Besides, the anodising industry must also remember that degraded sulfuric acid must be neutralised to a pH level between six and eight before discharging.

  • To prevent water pollution, a State Board may instruct any person in charge of any establishment or electroplating and anodising industry to provide information related to the installation, construction or operation of such unitor any addition or extension thereto in the such establishment or of any disposal system.
  • No person must intentionallyallow or cause any harmful, poisonous orpolluting matter determined according to the standards set by the State Board to enter into stream/well/land.
  • Subject to the provisions, no person must, without theprevious approval of the State Board, -
    • bring into use any modified or new outletsfor sewage discharge; or
    • establish any operation/process/treatment and disposal system or industry, including electroplating and anodising industry,which is expected to discharge trade effluent or sewage into a water body or on land; or
    • start to make any new discharge of sewage.
  • Provided that the person in the process of starting anyprocess or industryjust before the implementation of theWater (Control and Prevention of Pollution) Amendment Act, 1988, for which noconsent was requiredbefore such commencement, may resume to do so for three months from such initiation or, if he has applied for such consent, within three months, till thedisposal of such application.
  • The occupier is responsible for the secure and environmental freindly management ofhazardous and other wastes.
  • An occupier mustpracticeminimisation, prevention, recovery, and utilisation, including co-processing, reuse, recycling and safe disposal.
  • The hazardous and other wastes must be transported from an occupier's establishment, including the electroplating and anodising industry, to an authorised disposal facility or an actual authorised user according to the provisions of the rules.
  • The hazardous wastes generated in the occupier’s unitmust be sent or sold to an actual authorised user.Or else it must be disposed of in an authorised disposal unit.

Why electroplating and anodising industry is essential?

Increasing growth in industrial and construction industries, surging demand for related metal products, emerging economic conditions in developing nations, urbanisation development and technological advancements are the major factors affecting the global electroplating and anodising industry market growth.

Note -Industries involved in manufacturing using anodising, forging and casting, dyeing, coal-fired boilers, pickling, and electroplating will confront closure action in case found operating in non-conforming areas.

The process involved in electroplating

Before starting the electroplating and anodising industry, it is important to know the process in detail. Both the cathode (the metal part to be coated) and the anode are dipped in an electrolytic bath. This bath comprises a solution of salts, including the metal to be plated. A direct current (DC) is passed through the solution. This affects the transfer of metal ions onto the cathodic surface, thereby plating the metal onto the metal.

The process involved inAnodizing

Anodizing works by dipping the part of the metal into an acid electrolyte bath. It is then followed by electrifying them. An electrochemical process converts the metal surface into an attractive and durable anodic oxide finish.

Market analysis of the electroplating and anodising industry
