Now, let’s talk tapioca, which Keralites love eating. Yep, those crispy tapioca chips you love munching on? Turns out, they’re not just delicious; they’re also a goldmine for biogas. You see, every ton of tapioca processed leaves behind nearly 350 kg of solid waste. But instead of letting it go to waste, Kerala is turning it into a powerhouse of biogas. Each ton of this solid waste has the potential to churn out 335 m3 of biogas — that’s equivalent to nearly 500 units of power. And don’t even get me started on the liquid waste — it’s a biogas-generating machine, capable of producing approximately 3.6 m3 of biogas or 5.4 units of power per m3.

Now, let’s talk about water hyacinth — the pesky weed causing chaos in Kerala’s waterways. Despite its destructive tendencies, water hyacinth holds significant potential for biogas generation in Kerala. Research suggests that this relentless weed could produce about 0.014m3 of biogas from just one kilogram of plant material. That’s nearly 85% water turned into energy! However, due to ecological concerns, we’re still figuring out the best way to tap into this potential without causing more harm than good.

Leading the charge in waste management in kerala and biogas, the future looks brighter than ever. Large-scale plants of biogas in Kerala processing not only household waste but also agricultural and industrial streams, creating a circular economy where nothing goes to waste. And with advanced technologies converting biogas into clean fuel for transportation, Kerala is on track to reduce its carbon footprint and usher in a new era of sustainable mobility.

But it doesn’t stop there. Kerala is also nurturing a biogas ecosystem, where entrepreneurship flourishes, and job opportunities abound. With each household embracing biogas as a clean, green energy source, we’re one step closer to reducing our dependence on fossil fuels and building a cleaner, greener future for generations to come.
