Mexico: Cemex's waste management subsidiary Regenera has signed a deal with the municipal council of Huajuapan de León to receive the latter's sorted non-recyclable municipal solid waste (MSW). Under the deal, Regenera will receive up to 6000t/yr of MSW, which it will supply to Cemex's Tepeaca cement plant in Puebla.

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).

Mexico: Cemex Mexico plans to install hydrogen injection systems at four cement plants across Mexico. The producer will use the technology to increase alternative fuel (AF) substitution at the plants by 8 - 10%. A 40% reduction in Scope 3 purchased fuel emissions forms part of Cemex's 2020 -2030 CO₂ emissions reduction strategy. Through the decarbonisation and circular economy pillars of its Future in Action plan, the group aims to become carbon neutral by 2050.

Cemex Mexico president Ricardo Naya said "Hydrogen is a key technology to accelerate the implementation of our climate action roadmap."

The El Financiero newspaper has reported that Cemex set a new group record AF substitution rate of 34% in September 2022. It uses hydrogen at all of its European cement plants and at one plant in the Dominican Republic.

Mexico: Cemex reported 29% alternative fuel (AF) substitution in its global operations in 2021, according to its Integrated Report for the year. The report stated that the group reduced its CO₂ emissions per tonne of cementitious material by 4.7% year-on-year.

Mexico: Cemex’s Torreón cement in Coahuila has concluded its first 100% alternative fuel (AF) trial run.

Chief process officer Gerardo Castilla said that the move is ‘A small step for Cemex but a big step for the world.’ He added “Let’s go for more.”

Mexico: Cemex has acquired waste management company Broquers Ambiental. The company manages the separation, recovery and treatment of municipal solid waste (MSW) generated in the city of Queretaro. MSW from the company will be used as an alternative fuel at Cemex’s local cement plants. This acquisition is part of its Future in Action program, aimed to achieve carbon neutrality.

“With this acquisition, at Cemex, we are firmly committed to the circular economy by integrating our value chain to the production of climate-friendly fuels that we use in cement production. Our objective for this year is to double Broquer´s capacity and thereby contribute to the progress towards sustainability in the city of Queretaro, as well as the transformation of Mexico towards a green economy,” said Ricardo Naya, President of Cemex Mexico.

Broquers expects to increase the current staff by 50 new employees in 2022 to expand its processing capacity. The waste management company was reportedly the first plant of its kind in Mexico to use waste separation equipment in line with European standards for waste treatment.

Mexico: Switzerland-based LafargeHolcim’s US subsidiary Geocycle has signed an agreement with the City Council of Macuspana in Tabasco for the removal of 21,600t/yr of inorganic waste for sale to cement producers as alternative fuel (AF) for calciners. The company has inaugurated a US$1.3m waste processing plant for the purposes of meeting its commitment. Geocycle Mexico general director Sven Ritschard said, “This typifies the circular economy and is positive for all parties involved.” The waste would otherwise have gone to landfill.

Mexico: Geocycle Mexico processed 0.41Mt of industrial and municipal waste in 2018. The subsidiary of LafargeHolcim estimates that it will process around 0.46Mt in 2019. It supports the handling, treatment and co-processing of waste at LafargeHolcim’s cement plants.

Mexico: France’s Veolia has signed a deal with Cementos Moctezuma to build a US$4.8m waste processing unit in San Luis Potosí state. Once operational the unit will be able to process up to 40,000t/yr of industrial waste, according to the Expansión newspaper.

Mexico: Residents from El Refugio, Atotonilco de Tula have complained about the unauthorised burning of yires at Cementos Fortaleza’s El Palmar plant. The Secretariat of Environment and Natural Resources stopped tires being burned at the plant in February 2019 due to a lack of an impact study and an environmental licence, according to the El Universal newspaper. Residents allege that the plant has been burning tyres at night since the ban. They are concerned about health issues resulting from burning tyres.
