Adani Portfolio: Adani Cement’s Geoclean creates a circular economy Adani Portfolio: Manufacturing its first wind blade, a milestone in India’s energy landscape ONE OF THE BIGGEST CHALLENGES IN INDUSTRIAL OPERATIONS IS THE GENERATION OF PLASTIC THAT CANNOT BE PROCESSED IN THE USUAL WAY. The convenient result: landfilling. Until Adani Cement’s waste management arm – Geoclean – began to address this challenge. This Ambujanagar-based team focused on the development of a technology by which solid and liquid wastes could be processed with the objective to minimise landfilling and enhance resource conservation. This timely co- processing in the cement kiln resulted in simultaneous material recycling and energy recovery from waste in thermal process of cement manufacturing. On one hand, this technology substitutes traditional fuel and raw materials in the cement manufacturing process; on the other hand, it provides sustainable waste management solutions to waste generators. The proof of the effectiveness of the pioneering concept is reflected in the numbers: Geoclean has established six pre-processing and 14 co-processing facilities across India; the technology has processed more than 13,00,000 tonnes of waste a year, supported by specialised waste storage spaces, THE ADANI PORTFOLIO EMBARKED ON A MISSION TO EXPLORE EVERY PERMUTATION OF TOWER TYPE AND HEIGHT WHILE INVESTING IN THE WIND ENERGY BUSINESS. The Group sought to commission a groundbreaking 5.2 MW turbine with a tower design that would be distinct from its Prototype-1 (tubular tower). The Group engaged in extensive research to demonstrate that the new wind turbine generator would reach a towering 140 meters. This was intended to comprise a hybrid structure - lattice and tubular components - paired with an innovative blade manufactured by ANIL. The roadmap was challenging: designing the lattice-tubular hybrid tower to address stringent load, blade length and blade stiffness. The Group responded with the creation of the adaptor piece, a critical transition point bridging the lattice and tubular structures. The result was that the Group curated a tower design with a lattice base measuring 27.6 x 27.6 m, rising to 57 m, crowned with a lattice top spanning 13 x 13 m. The adaptor piece, a marvel of engineering, transitioned from a 13m square to a 5m circle within a mere 5m height. feeding set-ups, and state-of-the-art laboratories. The result is that Gujarat has mitigated the challenges of plastic waste pollution by co-processing solid and liquid waste provided by the state government, state pollution control board, and industries. It assists industries that generate significant plastic waste (in Vapi, Dahej, Ankleshwar, Surat and Vadodara) in suitable and prudent waste disposal. The waste streams co-processed at the plant comprise plastic waste, trade rejects, refused derived fuel, and industrial waste (sludges, liquid and solid waste) leading to moderated landfilling. Besides, Geoclean has graduated a processing function into a solution by offering a range of waste management services – assessment, consultation, laboratory analysis, waste characterisation, logistics, transportation, and waste preparation for co-processing. Geoclean addresses more than 500 pan-India customers, comprising industrial and service companies, municipalities, and waste management firms. For better tomorrows. The result was a design featuring a 57.5m long lattice section, 5m long adaptor section, and a tubular section. However, this innovation came with a unique challenge – the adaptor piece weighed 200 tonnes, necessitating its complex manufacture in two pieces within a brief timeline. The Adani team countered a high water table, creation of a specialised crane platform, creation of an access road to accommodate heavy equipment and addressing Cyclone Biparjoy. Eventually, the team delivered in August 2023, a testimony to innovation, excellence and perseverance. The Group built a 1.5 GW wind turbine manufacturing and assembly unit from design in a record one-and-a-half years. The Group’s 5.2 MW onshore wind turbine is a technology disruptor in the global wind energy sector, the largest in India and one of the most powerful globally. The Group’s proactive adoption of next-gen technology and digitalisation resulted in it being ranked as the top performer for six consecutive years by PVEL, a leading independent test lab for the downstream solar and energy storage industry. The Group is a market leader in the Pradhan Mantri Kisan Urja Suraksha Evam Utthaan Mahabhiyan (PM- KUSUM) segment and one of the largest solar panel exporters from India.
