From the rudimentary water closets of ancient Rome to the ornately decorated thrones of European royalty, toilets have served as a fascinating yet often under-appreciated window into human history and innovation. These early lavatories, while marvels of their time, often came at a cost: inefficiency and a heavy environmental footprint. Fast forward to today, and the focus has shifted dramatically. New-age toilet technologies are not just about creating a more comfortable and hygienic experience; they’re revolutionising sanitation by tackling the biggest environmental challenges associated with traditional toilets. By embracing water conservation, waste-to-resource technology, and smart design principles, these advancements are transforming toilets from environmental burdens into bastions of sustainability.
Water Conservation: The Biggest Battle
Traditional toilets can be surprisingly water-hungry, with a single flush using as much as 22 litres of water, according to the Environmental Protection Agency. This excessive water usage not only strains freshwater resources but also puts additional pressure on wastewater treatment facilities. Not to mention that it’s a staggering amount of water considering that over 2 billion people globally lack access to safe drinking water.
New-age toilet technologies are tackling this challenge head-on, offering solutions that promote water conservation without sacrificing performance:
Dual-flush toilets: These toilets empower users to choose between a full flush for solid waste and a partial flush for liquids, significantly reducing overall water usage.
Low-flow toilets: Designed with narrower pipes and efficient flushing mechanisms, low-flow toilets use less water per flush while maintaining optimal performance.
Vacuum toilets: These innovative systems utilise compressed air instead of water to remove waste, making them ideal for water-scarce regions or situations where water conservation is paramount.
Waste Management: From Burden to Resource
Human waste, if not properly managed, can be a significant source of waterborne diseases and environmental pollution. According to the World Health Organization (WHO), inadequate sanitation contributes to over 1.4 million deaths from diarrhoeal diseases annually. However, innovative toilets are tackling this challenge by transforming waste into a valuable resource:
Composting toilets: These toilets separate liquid and solid waste, offering a sustainable solution for off-grid locations or areas with limited access to water or sewer systems. The solid waste undergoes a composting process, turning it into a nutrient-rich fertiliser that can be used for gardens, reducing reliance on chemical fertilisers and promoting sustainable land management.
Biogas toilets: These innovative systems utilise anaerobic digestion, a natural process that breaks down organic matter in the absence of oxygen, to convert human waste into biogas. Biogas is a clean-burning renewable fuel source that can be used for cooking, lighting, or heating homes, reducing reliance on traditional fuels like firewood or kerosene. This not only improves indoor air quality but also combats deforestation and greenhouse gas emissions. Additionally, the leftover digestate from the biogas production process can also be used as a fertiliser, further maximising resource recovery.
Space Age Solutions for Earth
Space exploration, often seen as a futuristic endeavour, has surprisingly yielded valuable insights for tackling sanitation challenges on Earth. Spacecraft, by their very nature, must be self-sufficient and operate in closed-loop systems, demanding efficient and reliable waste management solutions. These space-age technologies can now be adapted to revolutionise sanitation on our own planet:
Water purification systems: Today, many advanced water purification systems use membrane filtration, ultraviolet radiation, catalytic oxidation and electrochemical processes to remove contaminants and pathogens from water, producing clean water for drinking, washing and irrigation. These systems are based on the technologies used to recycle water on the International Space Station (ISS) and other spacecraft. The ISS employs a state-of-the-art water recovery system that recycles an impressive 93% of the water present on board, even including sources such as urine, sweat, and condensation. Back on earth, this technology can help us purify lower grade water to make safe, potable water available to communities that would otherwise have to do without.
Microbial fuel cells: Over the years, NASA has funded projects to explore the use of microbial fuel cells to generate electricity from waste organic material. In simple terms, this technology uses microorganisms such as Shewanella oneidensis MR-1 to convert waste organic material (including human waste) to electricity through biological processes. The heart of this breakthrough is the microbial fuel cell, a bio-electrochemical device generating “green energy” while addressing wastewater treatment.
Sustainable Materials and Smart Design
Sustainable sanitation goes beyond just water conservation and waste management. Innovation is also redefining the toilet through material choices and smart design principles:
Durable and Recyclable Materials: Traditional toilets often rely on materials like porcelain, which while durable, can be energy-intensive to produce and difficult to recycle at the end of their lifespan. Innovative toilet technologies are embracing more sustainable materials like stainless steel or reinforced plastic. These materials offer extended lifespans, reducing waste generated from frequent replacements. Additionally, designing toilets for easy disassembly facilitates the recycling of materials at the end of their useful life, promoting a more circular economy within the sanitation sector.
Mission Swachhta aur Paani: A Catalyst for Change
The journey from cutting-edge technology to widespread sanitation solutions is not a simple one. Affected communities need to be actively involved, funding secured, and stakeholders convinced of the benefits. Project management and vendor engagement add further layers of complexity. Even with innovative solutions readily available, the path to real-world implementation can be long and arduous.
However, the first step is always awareness. Here, Harpic, a leading name in Indian lavatory care, has played a crucial role. For decades, Harpic has been a vocal champion for toilet hygiene through thought-provoking campaigns and impactful outreach programs. Three years ago, Harpic partnered with News18 to launch Mission Swachhta aur Paani, a movement dedicated to achieving inclusive sanitation for all.
Mission Swachhta aur Paani goes beyond just building toilets; it advocates for a future where everyone – regardless of gender, ability, caste, or class – has access to clean and hygienic sanitation facilities. The initiative recognizes that clean toilets are a shared responsibility, requiring collaboration across diverse stakeholders. This includes government officials, NGOs, sanitation workers, educators, and the public. By fostering intelligent dialogue between these groups, Mission Swachhta aur Paani leverages the extensive reach of News18 to shine a light on the challenges faced by our sanitation infrastructure and the dedicated individuals who maintain it.
Mission Swachhta aur Paani doesn’t just raise awareness; it empowers you to engage and participate. It invites you to contribute your knowledge and help move the conversation forward. Ultimately, sanitation is a concern for all of us. If fostering open dialogue about toilets can lead to cleaner and greener lives, then why hesitate to talk about it? Join us here, lend your voice to the growing call to action, and help us create a Swasth and Swachh India for everyone.
