10.2.1. Environmental Issues and Challenges

It is estimated that 75% of electronic items are stored due to uncertainty of how to manage it. These electronic junks lie unattended in houses, offices, warehouses etc. and normally mixed with household wastes, which are finally disposed off at landfills. This necessitates implementable management measures.

A significant number of electronic items (75%) are stored and not properly managed. Many people are uncertain about what to do with old electronics, leading to accumulation in homes and offices. These items often mix with regular household waste, ultimately ending up in landfills, which presents a challenge for waste management. Proper measures must be put in place to handle e-waste effectively.

Imagine having a treasure chest filled with old toys that you no longer play with, but instead of giving them away or discarding them, you keep them locked up somewhere. This clutter takes up space and adds to your stress, similar to how e-waste clutter accumulates in homes and contributes to pollution.

In industries management of e-waste should begin at the point of generation. This can be done by waste minimization techniques and by sustainable product design. Waste minimization in industries involves adopting: • inventory management, • production-process modification, • volume reduction, • Recovery and reuse.

E-waste management in industries should start right where the waste is generated. Companies can implement techniques to minimize waste through better inventory management, modifying production processes, reducing the volume of waste, and finding ways to recover and reuse materials. This proactive approach helps to reduce the amount of waste produced before it even becomes a problem.

Think of a restaurant that decides to plan its menu around seasonal ingredients. By doing so, it minimizes food waste because it uses ingredients that are fresh and in season rather than letting surplus food spoil. Similarly, companies can streamline their processes to avoid creating excessive e-waste.

Proper control over the materials used in the manufacturing process is an important way to reduce waste generation. By reducing both the quantity of hazardous materials used in the process and the amount of excess raw materials in stock, the quantity of waste generated can be reduced. This can be done in two ways: establishing material-purchase review and control procedures and inventory tracking system.

Inventory management is crucial for reducing e-waste. Companies should keep track of the materials they purchase and use, aiming to order only what they need. By reviewing material purchases and using an inventory tracking system, companies can limit excess inventory that could lead to waste. This careful management helps to reduce the overall generation of waste.

Consider a baker who only buys the flour and ingredients they need for the day's orders. By avoiding over-purchasing and wasted ingredients, they keep their kitchen organized and efficient, similar to how businesses should manage their materials to avoid e-waste.

Changes can be made in the production process, which will reduce waste generation. This reduction can be accomplished by changing the materials used to make the product or by the more efficient use of input materials in the production process or both.

By modifying production processes, companies can find new methods that generate less waste. This may involve changing materials to eco-friendlier options or improving the efficiency of how existing materials are used. Through such modifications, waste can be drastically reduced.

Think of a gardener who decides to use compost instead of chemical fertilizers. By changing the materials they use, not only do they reduce waste, but they also create a healthier garden. Similarly, companies can choose better materials to minimize waste.

Volume reduction includes those techniques that remove the hazardous portion of a waste from a non-hazardous portion. These techniques are usually to reduce the volume, and thus the cost of disposing of a waste material.

Volume reduction techniques focus on separating hazardous waste from non-hazardous waste to make disposal easier and cheaper. By doing this, companies can lessen the amount of waste that needs to be processed or thrown away. It helps in making recycling and reuse of materials more feasible.

Imagine a family sorting through their recycling: they separate metals, plastics, and paper so they can reduce the amount of garbage they produce. This sorting allows for better recycling choices and reduces overall waste in the landfills.

This technique could eliminate waste disposal costs, reduce raw material costs and provide income from a salable waste.

Recovery and reuse techniques can significantly lower costs by eliminating the need for waste disposal and reducing the need for raw materials. Additionally, companies can generate income by selling materials that would otherwise be discarded. This creates a more sustainable business model that benefits both the company and the environment.

Think of a person selling their old clothes at a garage sale instead of throwing them away. Not only do they make some money back, but they also help someone else by offering reusable items. This practice can translate to businesses, too, where recovered materials can be repurposed.

Minimization of hazardous wastes should be at product design stage itself keeping in mind the following factors: • Rethink the product design: Efforts should be made to design a product with fewer amounts of hazardous materials. • Use of renewable materials and energy: Bio-based plastics are plastics made with plant-based chemicals or plant-produced polymers rather than from petrochemicals. • Use of non-renewable materials that are safer.

Sustainable product design aims to minimize hazardous waste right from the design stage. This can be done by rethinking product designs to use fewer hazardous materials, incorporating renewable resources, and ensuring that non-renewable materials used are safer for the environment. Focusing on sustainability in design can prevent e-waste before it even exists.

Think of an architect designing a building that uses solar panels and recycled materials. By incorporating sustainable features from the start, the building minimizes environmental impact over its lifetime, similar to how products should be designed to limit e-waste.
