ENVIRONMENTAL GUIDELINES

Lead is the most recycled one of all the common non-ferrous metals. The main input for Lead Recycling is Lead-Acid Battery Scrap. The Lead-Acid Battery Industry is acknowledged worldwide as a model for product recycling. Environment-friendly Battery Recycling prevents large amounts of Lead from going waste, saves energy and reduces pollution as compared to primary production. It also facilitates recycling of other materials such as Polypropylene Battery Casings

As Lead is a hazardous metal, following environmental guidelines and eco-friendly business practices is important in Battery Recycling. Gravita has been fully committed to the environment and provides environment-friendly solutions since inception. All of Company’s business processes and operations are aligned with environmental aims. Developing more effective pollution control solutions and promoting modern pollution control technologies is one of our thrust areas. We provide plants integrated with efficient pollution control modules, at competitive capital costs, with the objective of widespread adoption of modern, eco-friendly designs and technologies.

Lead Emission Control

 All processing industries generate waste. The quantities generated and their potential impacts depend on many factors, including the level of industrial development, the way in which wastes are managed, the existing state of the local environment and the capacity of the receiving media. The gases & fumes generated in the system are effectively controlled by the Pollution control Equipments. The amount of Lead content that flue with these gases are being collected at every stage of pollution control equipments.
• SOX – Sulphur content present in the gases are being treated with water
• CO, Lead Dust, Lead Ash etc. – These are controlled by different sections of Pollution Control Equipments.
• NOx – In our case of operation, No Nitrogenous components are produced because of the lower level of temperatures.

 

Meeting Exacting Environmental Standards

Lead Emission Standards 

Environmental standards relevant to the battery recycling industry vary widely among countries and international organizations and are in a constant state of flux. The main standards are:

 
.
