The UN’s fourth Global E-waste Monitor (GEM) reported in 2024 that electronic waste is accumulating five times faster than it is being recycled. In 2022 alone, 62 million tonnes of e-waste were generated, enough to fill 1.55 million 40-tonne trucks, which, if lined up bumper to bumper, could encircle the equator. This data, compiled by ITU and UNITAR, highlights the urgency of addressing e-waste management.
A major contributor to this surge is the widespread adoption of smartphones, tablets, laptops, computers, televisions, and monitors. Frequent model upgrades, particularly in consumer electronics, accelerate disposal rates. Larger television screens and monitors, including CRTs, LCDs, and LEDs, add to the challenge, as they contain hazardous materials that require careful handling.
With home entertainment setups becoming central to modern households, driven by the rise of OTT platforms and gaming, sustainable choices in this sector are essential. Exploring alternatives such as UST laser projectors, which may offer a lower environmental footprint compared to traditional televisions and lamp-based projectors, can be a step toward achieving sustainability in the home entertainment segment, experts feel.
“Laser-powered UST projectors are more energy-efficient than lamp-based models and consume less power per square inch of display compared to large TVs, which require more energy to illuminate wide LED or OLED panels. For instance, high-end televisions can draw over 300W, whereas laser UST projectors will operate at 150W or lower. This leads to lower electricity costs for consumers and a smaller carbon footprint, supporting sustainability, “ says Sushil Motwani, Founder of Aytexcel Pvt. Ltd, the official representative of Formovie projectors in India.
He says that various studies have pointed out that mercury vapour lamps used in older projectors generate toxic waste, contributing to pollution. “Modern laser projectors use laser diodes as a light source, which are more energy-efficient and have a longer lifespan. They help in avoiding hazardous materials like mercury and their ultra-compact design reduces heat emissions. Most of these models are built using recyclable materials and environmentally friendly manufacturing processes,” adds Motwani.
According to him, modern UST projectors integrate advanced technologies that combine multiple device functionalities into a single unit, resulting in power-saving benefits. “This integration of features reduces the need for extra devices. For example, today’s UST projectors come with built-in speakers, native apps and Google TV, minimising dependence on additional equipment that could increase power consumption,” explains Motwani.
He adds that the latest technological advancements ensure that UST projectors remain relevant without the concern of becoming outdated. “With a lifespan exceeding 25,000 hours, laser projectors last much longer than traditional lamp-based models, which require frequent bulb changes. This durability reduces the need for component replacements, decreasing electronic waste and minimizing environmental impact,” concludes Motwani.
