Context

Recently, the government has introduced new guidelines for solid waste management in coastal aquaculture units to promote sustainable practices in the aquaculture sector. 

• The Ministry of Fisheries, Animal Husbandry and Dairying (MoFADH) published the regulations that advocate reducing and managing waste across all stages of production, including hatcheries, farms, and breeding centres. 

Challenge of Solid Waste Management In Aquaculture Units

• Concerning Data: According to a report by The Energy and Resources Institute (TERI), India produces over 62 mn tonnes (MT) of waste in a year. 
  • Untreated Waste: Most of the waste generated remains untreated and even unaccounted for. Only 43 MT of the total generated waste gets collected, with 12 MT being treated before disposal, and the remaining 31 MT discarded in waste yards.
• Concerns: Inadequate waste collection, transport, treatment, and disposal have become major causes of environmental and public health concerns in India.
• Need for Guidelines: To counter growing concerns over the environmental impact of coastal aquaculture, which can contribute to rising levels of pollution if not managed effectively.

About Guidelines On Solid Waste Management In Aquaculture Units

• Deals With: To delineate protocols spanning from waste handling to prohibiting its burning.
• Aim: To minimize waste generation and ensure its responsible disposal.
• Provisions: 
• • A Systemic Approach: To identify, categorize, and manage waste streams effectively. 
  • Responsibility: Each unit will have to assess waste generation, segregate solid waste into biodegradable, non-biodegradable, and hazardous categories, and provide adequate bins for segregation.
  • Actions Required: The facility managers will have to plan waste transportation and implement reuse or recycling measures to minimize environmental impact.
  • Ban on Plastic Burning: The guidelines also impose a ban on the burning of plastic.
    • Plastics of any grade shall not be burnt at any time by the units, and shall be handed over to the local body or the appointed agency.
  • In-house Sewage Treatment Plants: Larger units generating significant sewage are also required to operate in-house sewage treatment plants meeting Pollution Control Board standards. 
  • Methods Recommended: Various methods such as fermentation and composting are recommended for biological waste management. 
    • Incineration of old or dead animals is advised in certain facilities.
  • Adherence to Safety Norms: Storing of fuel, oil, and lubricants must adhere to legal requirements, with regular maintenance and staff training to prevent spills and ensure safety compliance.
• Emphasis On: The importance of temporary storage and proper disposal. 
  • Each unit is required to maintain adequate temporary storage capacity to handle different categories of waste effectively. 
  • Recyclable Non-degradable Waste: It can be stored and periodically sold or handed over to recyclers based on storage facility capacity and disposal schedules.
  • Designated Space for Landfill Disposal: Units will also have to create designated spaces for landfill disposal. 
• Challenge: The real challenge lies in the effective implementation of guidelines.
  • Despite existing principles, pollution persists, indicating gaps in enforcement. 
• Need To Do: The government should impose stringent penalties and robust enforcement measures to ensure the guidelines are adhered to effectively.
