10.1. MANAGEMENT OF E-WASTES

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 amount of electronic waste (e-waste) remains unaddressed, with 75% of electronic items being stored because people are unsure about how to dispose of them. This results in accumulation in various places like homes and offices, eventually leading to these items getting mixed with regular waste and ending up in landfills. Therefore, effective management strategies are required to handle e-waste responsibly.

Think of e-waste like old clothes or toys that you don't use anymore but hang onto because you’re unsure of how to get rid of them. Instead of just piling them up in the closet (like e-waste piling up in homes), we need a systematic way to recycle or donate them.

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.

E-waste management effectively starts where it is created—in the industries that produce electronic goods. Companies can implement waste minimization techniques and design products in a way that results in less waste. This proactive approach helps reduce the overall amount of e-waste generated.

Just like a baker who measures ingredients carefully to avoid leftover dough, industries too can monitor and manage their resource use to prevent producing extra waste.

Waste minimization in industries involves adopting: • inventory management, • production-process modification, • volume reduction, • Recovery and reuse.

Industries can adopt several techniques to minimize waste. This includes inventory management to track materials, modifying production processes to use fewer resources, employing volume reduction techniques to lessen waste size, and implementing recovery and reuse strategies to make the most out of discarded materials.

Imagine sorting through a cluttered garage. By taking inventory of what you have, getting rid of unnecessary items, and finding new uses for things you don't need anymore, you manage your space better. Industries can do exactly that with their materials.

Proper control over the materials used in the manufacturing process is an important way to reduce waste generation. This can be done in two ways i.e. establishing material-purchase review and control procedures and inventory tracking system.

Effective inventory management is crucial for reducing waste in production. By keeping strict controls on material purchases and tracking inventory accurately, companies can minimize the amount of excess materials and hazardous materials that contribute to waste generation.

Think of it like keeping a well-organized kitchen. If you know exactly what ingredients you have (inventory tracking), you won’t buy duplicates or let food spoil (material over-purchase), reducing 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.

Modifying production processes is another effective way to manage e-waste. Companies can choose different materials that are less harmful or inefficient and utilize materials in a more productive manner to lower waste production.

Imagine if a chef switched from using regular cooking oil to a healthier one. Not only does it produce fewer unhealthy leftovers, but it also enhances the dish. Similarly, changing materials in production can lead to better outcomes with less 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 refers to methods that separate hazardous waste from non-hazardous waste so that the overall waste volume can be minimized. This helps in reducing disposal costs and makes recycling efforts more effective.

Think of recycling as packing for a trip. If you sort through your items and take out only the essentials, you end up with lighter luggage (less volume) making it easier and cheaper to travel (dispose of waste).

This technique could eliminate waste disposal costs, reduce raw material costs and provide income from a salable waste. Waste can be recovered on-site, or at an off-site recovery facility, or through inter-industry exchange.

Recovery and reuse of materials can be highly beneficial for industries. Not only can it lower waste disposal costs, but it can also decrease raw material expenses and generate revenue from reusable materials, creating a sustainable loop in production.

Consider a family that collects glass bottles to return them for cash instead of throwing them away. By reusing and recovering materials, they save money and reduce waste, similar to how industries can profit while being environmentally conscious.

Minimization of hazardous wastes should be at product design stage itself keeping in mind the following factors...

To minimize hazardous waste from the start, product designers should take responsibility during the design phase. This includes creating products with fewer hazardous materials, using renewable resources, and ensuring the products can be reused or repaired.

Just as a gardener plans where to plant seeds to maximize future growth, designers need to think ahead about their products to ensure they minimize waste and maximize utility for the future.
