ReClaim : Reclaming waste and restoring earth

                                                                                                  Reclaiming waste and restoring earth

 

Problem

Landfills release methane a greenhouse gas that is about 80 times stronger than CO₂. They also leak toxic liquids into the soil and water which can harm plants, animals, and people. Cities are producing more waste than they have space to handle. Current waste to energy systems burn trash, which releases CO₂ and does not fully reduce pollution. Because of this landfills are still major sources of climate change and pollution making it harder to achieve netzero goals.

Market Gap

Current methods to capture methane are mostly for big sites, expensive, and hard to scale. Recycling does not reduce methane from landfills and struggles with mixed waste. Carbon capture usually does not focus on landfill gases, which make up 11% of the world’s methane. Right now there is no single system that can capture methane, clean waste, and reuse resources all together.

 Solution : ReClaim units

Modular units deployed at landfill sites to:

  • Capture methane via biofilters and membrane systems that actively extract methane from landfill surfaces and gas vents.
  • Convert methane into renewable fuels through catalytic reformers (which reform methane into syngas) and microbial bioconversion, where specialized microbes produce upgraded biogas.
  • Mineralize captured CO₂ by reacting it with alkaline industrial waste or minerals to form stable solid carbonates, creating carbon negative construction aggregates.
  • Treat toxic leachates using a combination of biological (aerobic and anaerobic microbial digestion), chemical (oxidation and precipitation), and physical (membrane filtration, adsorption) technologies, monitored and controlled by integrated bio-indicator sensors (BITE tech) that detect heavy metals and toxins in real-time for adaptive management.
  • Stabilize residual waste into inert construction bricks by employing waste solidification and stabilization techniques, binding contaminants into a safe matrix while producing durable, carbon negative building materials.

Scientific Mechanism

  • Methane from waste in landfills is pulled out using suction and filters with microbes that consume methane.
  • Membranes separate methane to concentrate it for energy use.
  • Methane is converted into a fuel gas called syngas using catalysts.
  • Microbes break down organic waste into biogas, which is cleaned and turned into renewable gas or hydrogen.
  • CO₂ reacts with waste materials to form solid carbon that stays locked in building materials.
  • Toxic liquids from landfills are cleaned by microbes, chemicals, filters, and activated carbon.
  • Sensors track pollution continuously to keep treatment safe and effective.
  • Heavy metals and harmful chemicals are removed to protect soil and water.
  • Leftover solids are mixed with binders and hardened into bricks.
  • These bricks reduce landfill size and can be used for eco-friendly construction

 

Who Benefits?

  • pollution in cities reduced, land is reclaimed and gain the carbon credits.
  • Waste companies access new revenues.
  • Carbon credit buyers get verifiable impact credits.
  • Communities enjoy cleaner air, water, and repurposed land.
  • Construction receives carbon negative materials.

Why It Matters to Me

I want to reduce pollution and fight climate change by controlling methane from landfills, one of the fastest ways to slow global warming. I am motivated to stop toxic liquids from leaking into soil and water, keeping ecosystems and communities safe from harmful contamination. This project lets me turn a growing environmental problem into a local solution that improves air quality, cleans water, and turns waste into clean energy and useful materials. It’s about making real, visible benefits for people and the planet in their own communities.

Road Map

  • Prototype modular methane capture and leachate treatment unit with sensors.
  • Pilot with mid-sized city landfill demonstrating full system and monetization.
  • Scale to multiple sites and improve efficiency.
  • Monetize renewable energy, carbon credits, and recycled bricks.
  • Expand globally in rapidly urbanizing regions.

  • ReClaim is a really interesting idea. I like how it combines methane capture, leachate treatment, and resource recovery into a single system, turning environmental problems into practical solutions. To make it even stronger, it could include more details on energy efficiency, adaptability to different landfill types, and potential maintenance challenges. 
    • Thank you for your helpful feedback. You’re right energy use, adapting to different landfills, and maintenance are important to consider. I will make sure to include these details to make the idea stronger and more practical.
  • This is such a brilliant idea! It’s innovative, practical, and could make landfills part of the climate solution.
    • Thanks so much! I want to turn landfills from problems into part of the solution for the climate and people.
  • This *ReClaim* project is an excellent idea — it tackles one of the biggest environmental challenges by capturing landfill methane, treating toxic leachates, and even converting waste into renewable energy and eco-friendly building materials. The integration of sensors and modular units makes it scalable and practical for different cities. For improvement, the idea could focus on cost feasibility for large-scale adoption, long-term durability of bricks made from waste, and strategies for government or private sector partnerships to drive implementation. Adding clear pilot success metrics could also strengthen its impact.
    • Thank you for the great suggestion. I’ll refine my approach to address cost efficiency, test the longevity of construction bricks, and develop partnerships to support implementation. Clear success criteria will be defined for upcoming pilots.
  • Wonderful Idea, Kruthi! I've seen you work on this idea with lot of thought and am glad you're able to bring this to the world. It's ambitious but really grounded in practical science. I love how ReClaim doesn't just capture methane but also helps recylcle it into clean energy and full circle solutions. Working on ways to downsize it for smaller communities would be a real game changer would help more people benefit from cleaner waste management and help it have more reach. Just an area of exploration among many more. Let's keep it going!
    • Thank you for the support!
      ReClaim’s modular units are designed to be easily scaled and tailored for smaller communities to ensure wider accessibility. Making the system effective at different sizes is an important part of focus as we continue development.
