Sustainability is a trending topic today and it is the need to meet the demands of the present generation without compromising the ability of future generations to meet the same demand. This principle applies to many industries, including the automobile industry. It emphasizes the production of goods in a way that minimizes environmental damage, and electric cars are an example of this. According to an IBM study, 57% of consumers are willing to change their purchasing behavior to reduce negative environmental impacts. While smaller activities like recycling or shopping locally are easier than buying a car, they add to the growing commitment to sustainability. Cars play a vital role in the development of any country, facilitating the transportation of people and goods. The number of vehicles in India is increasing by millions every year. However, India has limited oil reserves and is highly dependent on oil imports to meet its fuel needs. Dependence on foreign oil and fluctuations in oil prices present significant challenges. The expanding Indian automobile industry is also affecting the country's economy. To address these issues, India is working to reduce its dependence on foreign oil imports and related costs. In addition, emissions from traditional fuels are a global challenge that increases air pollution and climate change. Due to India's growing transportation needs and population, the demand for vehicles is increasing every year. Road traffic is the main source of traffic emissions, most of which comes from internal combustion engine cars. These vehicles emit various pollutants such as carbon dioxide (CO2), nitrogen oxides (NOx), particulate matter (PM10) and ozone (O3).
Electric vehicles (EV) offer a comprehensive solution to these problems. They are environmentally friendly and emission-free, which makes them a key part of reducing pollution caused by traffic and promoting sustainability. Electric vehicles (EV) are powered directly by electric motor batteries, providing an alternative to traditional fuels such as petrol, diesel or gas. They are considered environmentally friendly due to their zero emissions. However, it is important to consider the environmental impact of manufacturing electric cars. Despite some of the environmental impacts of their production, electric cars offer long-term benefits by significantly reducing greenhouse gas emissions. Unlike internal combustion engines (ICEs), which burn fossil fuels and produce harmful carbon dioxide emissions, electric cars run without a tailpipe and produce no emissions. The main component of an electric car is its battery, usually a lithium-ion battery, which produces no pollution during charging or discharging. The production of electric vehicles is less resource-intensive than conventional vehicles, which gives them a significant environmental advantage. This efficiency is due to the simpler mechanics of electric cars compared to gasoline or diesel vehicles. In addition, electric cars eliminate the need for fossil-based products such as motor oil used in ICE vehicles, which contain toxic compounds that can pollute water sources and harm wildlife. In addition, electric cars reduce noise pollution because their electric motors run much more quietly than internal combustion engines. This noise reduction benefits both urban and residential areas, improving the quality of life and creating a more peaceful environment. In terms of sustainability, all electric cars are essentially electric vehicles that use electricity stored in batteries to power the engine. When these batteries are discharged, they can be recharged using electricity from the grid.
The sustainability of the production and disposal of electric car batteries is a cause for concern. The durability of batteries and chargers depends on the materials used, production processes and their disposal. The most important raw materials for battery production are lithium, cobalt and nickel. According to the Faraday Institute, global lithium production will need to quadruple and cobalt production will double to meet growing demand. These materials are mostly sourced from a limited number of countries, and mining has significant environmental impacts such as habitat destruction and pollution. The Democratic Republic of Congo supplies more than 60 percent of the world's cobalt, while large quantities of lithium are found in Chile, Australia and Argentina. Manufacturers must ensure a secure supply chain and sustainable raw materials. To promote sustainability, international efforts are underway to increase the transparency and traceability of these supply chains. Recycling of electric vehicle batteries is critical to their durability. Effective recycling processes help recover valuable materials, reduce demand for mining and minimize environmental impact. EV batteries are large and heavy and contain hazardous substances that require special skills and equipment to safely disassemble. Electric car batteries weigh around 300kg on average, although some models can weigh up to twice that. They consist of plastic, solvents, electronic components and small amounts of precious metals such as lithium, cobalt, copper, manganese and nickel. The costs associated with collecting, transporting and handling used batteries can be significant. Currently, recycling is often not economically viable without subsidies or legislative support. Recycling technologies continue to evolve and existing infrastructure is limited, requiring the development and expansion of efficient processes for the safe and efficient recycling of batteries.
Our solution for recycling electric car batteries includes five main steps:
1. Collect, repair and completely discharge the battery
2. Disassemble and send each component to the appropriate sector for recycling
3 Mechanical separation from the black mass of the elements that make up the battery.
4. Using hydrometallurgy to extract and purify metals from black pulp
5. Refining metals to purity levels so that they can be reused to make new batteries
In 2022, NITI Aayog proposed a new ecosystem with Battery-as -a - service (BaaS) model that meets battery safety standards. When changing the battery, electric cars exchange discharged batteries for charged ones at exchange stations. An exchange station installed in a certain location contains several batteries that are constantly charged. Electric vehicle users can designate an exchange station, exchange a low battery for a charged battery, and charge a dead battery to charge. For example, Tesla developed a battery recycling system to recover valuable materials. The goal is to create a closed-loop system for recycling electric car batteries and storing energy.
To ensure that your electric car contributes to sustainability, you can do the following:
1. Choose a renewable energy supplier for your home electricity when you charge your car at home.
2. Reduce your car's energy consumption by driving efficiently and avoiding unnecessary trips. 3. Maintain your car battery to extend its life.
4. Recycle your car battery at the end of its useful life.
5. Consider the entire life cycle of your car from production to disposal and choose a car with a low environmental impact.
Electric vehicles are indeed more environmentally friendly than traditional internal combustion engine vehicles. Although the production and disposal of electric car batteries present environmental challenges, the total life cycle emissions of electric cars are significantly lower. Electric cars emit no emissions, reduce noise pollution and are more energy efficient. The transition to electric vehicles, supported by the recycling of batteries, the acquisition of sustainable raw materials and the increase in the use of renewable energy in electricity production, promises to significantly reduce the environmental impact of traffic. Electric cars therefore represent a crucial step towards more sustainable and environmentally friendly transport and meet wider sustainability goals to meet current needs without compromising the ability of future generations to meet their own needs.
