India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.

The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.

Spain: Holcim España invested Euro4m in an upgrade to its 1.5Mt/yr Carboneras cement plant in Almería. Alimarket-Construction News has reported that the upgrade will raise the plant’s alternative fuel (AF) substitution rate to 70% and enable it to dispose of 50,000t/yr of waste through co-processing it as AF. Holcim España expects this to reduce its CO₂ emissions by 22,000t/yr.

Indonesia: Indocement Tunggal Prakarsa has engaged Japan-based environmental consultancy Amita Holdings to support a two-year feasibility study to investigate ways to make its cement production carbon neutral. The study will commence with trials of industrial wastes as alternative raw materials and municipal solid waste as refuse-derived fuel. Amita Holdings says that it is in the process of building a recycling-based society in Indonesia, in partnership with Indocement Tunggal Prakarsa.

Amita Holdings supported the establishment of the community-led Meguru waste sorting facility in Central Java. Two of Indocement Tunggal Prakarsa’s cement plants – the 18Mt/yr Citeureup cement plant and 4.1Mt/yr Paliman cement plant – are situated in neighbouring West Java.

US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant.

Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."

Press Trust of India News has reported that the contract covers nine municipal subdivisions of the city and will last until 2044. AWHCL said that the contract will enable it to develop the circularity of cement and concrete within the local economy. It expects to commission 600t/day-worth of waste processing capacity by March 2023. The waste management company expects a recovery rate of 25% recyclable materials.

AWHCL chairman and managing director Jose Jacob said "This sub-segment of solid waste management provides tremendous growth opportunities given the number of infrastructure development projects underway, and the government's push to accelerate the economic growth with infrastructure being one of the important growth pillars."

Philippines: CRH subsidiary Republic Cement and its waste management subsidiary Ecoloop are seeking to establish partnerships with 'sustainability-minded' organisations. BusinessWorld News has reported that Republic Cement and Ecoloop process waste for 12 private companies and 30 local government units. Philippines law will require that large organisations recover 80% of their plastic packaging waste by 2030. For 2023, the minimum is 2023.

Ecoloop managing director Angela Edralin-Valencia said “Our goal is to make our cement a greener and more environmentally friendly product. Our ambition is to replace 50% of our fuel consumption with alternative fuel (AF)." She added "A lot of investments have to be put in place from our end to get to that number, but we are still reviewing our options.”

Mexico: Cemex has launched its global waste management subsidiary Regenera. Regenera will be involved in the reception, management, recycling and coprocessing three major waste streams: municipal and industrial waste, construction, demolition and excavation waste (CDEW) and industrial by-products. It will tie in with Cemex’s own cement sustainability initiatives, for instance in its supply of waste recovered from the River Nile to Cemex Egypt’s Assiut cement plant for co-processing as alternative fuel (AF).

India: Adani Cement has announced the launch of a dedicated waste processing subsidiary called Geoclean. Geoclean will process waste for recycling and use as alternative fuel (AF) in its cement production and alternative raw materials in its production of other building materials. Geoclean inherits the projects and all 14 waste management plants of its predecessor company Geocycle India. The Orissa Diary newspaper has reported that Geoclean aims to help Adani Cement to co-process 3.7Mt of AF over the five-year period up to the end of 2027. This would raise its subsidiaries ACC and Ambuja Cements’ AF substitution rate to 30%, from 6% in 2021.

Adani Cement CEO Ajay Kapur said "We are committed to building a sustainable future by adopting clean and green technologies in our overall business. We have always believed in environmental conservation, and are committed to making the optimum contribution towards co-processing waste responsibly for a sustainable future. Adani Cement will continue its endeavours to promote sustainability and build a cleaner and greener planet."
