The world is facing an enormous waste management problem. Each year, humans generate around 2.01 billion tonnes of solid waste, and by 2050, this is expected to increase to 3.40 billion tonnes. Managing this waste has become a significant challenge for policymakers, waste collectors and landfill operators. Fortunately, artificial intelligence (AI) has emerged as a potential solution to this problem. AI has the potential to revolutionize the waste management industry by improving waste sorting, making recycling more efficient, and reducing landfill usage.
## The problem with waste management
There are two primary issues in modern waste management systems – inefficiency in recycling and reliance on landfills. Traditional recycling systems use large amounts of energy and time because sorting through the waste materials is an arduous process. Often, the process is manual, which means it is both time-consuming and prone to human error. Additionally, the lack of quality control in recycling can lead to contamination, which reduces the value of the recycled material and leads to environmental damage.
Landfills also pose a problem. They are environmentally harmful as they produce methane, a potent greenhouse gas, and attract vermin and scavengers that are problematic for both human health and the environment. Moreover, as urban populations explode, land becomes scarce, making it even more challenging to find suitable locations to establish new landfills and cover existing sites.
## How AI is used to improve waste management
AI can help solve these issues. For instance, AI-powered drones equipped with cameras can perform site assessments, collecting data that can help with streamlining the waste collection process. The data obtained from the drones can be used to develop algorithms that would enable waste collectors to avoid areas with minimal activity, hence, reducing fuel usage, saving time, and improving efficiency. Moreover, using AI in sorting and recycling will lead to a reduction in the cost of recycling facilities, which will increase the return on investment for recycling companies.
AI-powered robots have also been introduced to the market. Through machine learning, these robots can recognise different types of waste, separate recyclable materials, and throw away non-recyclables promptly. In addition, AI can be applied to identify the resource content of a single resource product through visible and ultraviolet spectroscopy. The technology can detect contaminants in waste and distinguish non-recyclable waste from recyclable waste, making the sorting process more precise.
Another creative way AI can help solve the waste management problem is through environmental monitoring. Sensors can be placed in and around landfills to monitor humidity, temperature, gas emissions, and other environmental indicators. This information can be transmitted through the cloud to AI systems, which can identify when an overload of a landfill is about to happen, helping waste management companies empty them in good time.
AI can also help reduce landfill usage by encouraging recycling. Machine learning algorithms can scan materials for recycling codes or read QR codes on packaging and direct customers to recycle bins. Additionally, through using Natural Language Processing (NLP) technology, waste management companies can receive data from social media to determine public perception about recycling and make necessary amendments to encourage recycling behaviour.
## Conclusion
Artificial intelligence proposes to revolutionize the way waste management is executed. AI is perfect for tasks that involve mathematical computations, analysis of images and texts, and of course, data handling. The application of AI technology to waste management can lead to more waste being recycled instead of being sent to landfills, and that will positively impact the environment by reducing greenhouse gas emissions and reducing the need to exploit new landfills. With AI, waste management operators can spot emerging issues earlier, carry out corrective measures more efficiently and with more precision, and make data-driven decisions with ease. Investing in AI can help prevent the environmental, economic, and social damage that comes with inefficient waste management systems, and in the long run, save a lot of money for governments, organisations and communities.
