Celebrating 25 Green & Glorious Years

Back in 1995, waste management was very different from what it is today. Similarly, technologies and innovation in the industry were relatively low. However, in the last decade, the global revolutions in waste management solutions have helped Mailhem expedite waste management processes and assist hundreds of businesses with newer technologies to handle all the waste — in kitchens, industries, and residences.

However, when the business began, waste management was new and had a lot of potential. This fuelled Col. Suresh Rege, the founder of Mailhem’s passion for doing something exceptional in the field of waste management.

Ever since its inception, Col. Rege has been instrumental in challenging the norm and creating new opportunities for every business to convert their waste into usable energy.

The next-generation environmental entrepreneur, Sameer Rege is a dynamic and passionate leader who plays an instrumental role in making the company the pride of India with innovative solutions.

Col. Rege’s Journey from Olive to Green

When Col. Rege decided to leave his successful career as an officer in the mechanized infantry of the Indian army to become an environmental entrepreneur at the age of 40, it was an unconventional decision with unbelievable commitment. While the world around him wasn’t sure if he’d made the right call, Col. Rege was determined to resolve the challenges around waste management and bring about sustainability, even when no one was really talking about it back in 1995. Taking leftover foods from the Army canteen when no other corporate trusted his R&D, he began his conversion of waste to gold! Today, he has hundreds of corporate clients who trust the technology, systems, and ideas of Mailhem Environment Pvt. Ltd.

His illustrious journey from the Indian army to India’s cleanliness drive is inspirational to say the least. He has also won the Lifetime Achievement Award at the CSR Global Green Awards in 2016, celebrating his vision towards a greener planet.

Moving forward, Col. Rege and Sameer Rege, the next-generation entrepreneur, want to be a global brand for waste management solutions and their constant R&D is definitely proving to be invaluable to multiple clients who are re-utilizing their wastes in unbelievable ways.

Contributing to Indore’s Smart City Mission:

Mailhem Environment Pvt. Ltd. completed a 15 TPD project for Indore Smart City Development Ltd. to convert organic solid waste into bio-CNG Generation Plant. With a 15 TPD segregated MSW capacity, the project model is EPC with three years O&M contract. The process includes Sorting — Shredding — Biomethanation — Biogas Purification & Compression — Cascade filling & BioCNG Dispenser at a land of approximately 1 acre.

We have successfully installed and commissioned 15TPD Biomethanation Plant for Indore Smart City Development Corporation Ltd, and we have been operating the same plant for the last 3 years. 500kgs of Compressed Biogas generated from this plant is filled into 6 to 7 buses of Indore Smart City.

Indore has been the cleanest city in India for four consecutive years and such plants help the city to lead the way towards sustainability.

Sustainability for the Future:

Mailhem Environment Pvt. Ltd. is now moving towards Atma Nirbhar Bharat and Swacch Bharat Abhiyan with continuous improvements in waste management solutions. The pandemic has had tremendous impact on the waste sector and thus, a number of municipal corporations are now adapting to newer waste management systems to assess and handle the situation. The per capita waste generation has increased from 0.26 kg/day to 0.85 kg/day and 80–90% of municipal waste is disposed of in landfills without the right management. Also, open burning is leading to air, water, and soil pollution, adding to the challenges for city’s cleanliness drives.

Mailhem Environment Pvt. Ltd. aspires to create a sustainable tomorrow with greener energy. The technological influence in handling wastes responsibly will help the business grow their reach into every town and city in the country and the world, so that waste finds a way to be useful.

Computer technology, composting initiatives, recycling programs, waste-to-energy, and regulations on collecting and processing waste will hopefully free our country and the planet from all the challenges of sustainability.

As a leader in conversion of biogas to Compressed Biogas (BioCNG) and its use as auto fuel, Mailhem’s strength is co-digestion of different organic substrates with varying retention time to produce power and Bio CNG. The company is also doing re-engineering projects Operation & Maintenance (O&M) of several waste management projects with over 25 contracts in hand currently. This is definitely a positive sign towards a new wave of waste management.

Mailhem Environment Pvt. Ltd. celebrates a legacy of 25 years, delivering sustainable solutions for green energy for the Indian waste management ecosystem.
