Canada: Minister of Environment and Climate Change, Steven Guilbeault, announced the reinvestment of up to US$1.6m from industrial pollution pricing proceeds into a new emissions reduction project at St Marys Cement in St Marys, Ontario. This initiative will involve the installation of a new kiln utilising low-carbon fuels, including discarded plastics, to reduce the use of carbon-intensive fuels used in the manufacturing process by up to 30%. The project aims for a reduction of over 39,900t of greenhouse gas emissions by 2030, according to Foreign Affairs news.
South Korea: South Korean cement manufacturers recently convened at an event hosted by the Korea Cement Association and the Korea Industry Alliance Forum to discuss how to achieve carbon neutrality. The industry currently faces financial challenges in upgrading equipment due to low cement prices. However, it has achieved a 20% decrease in greenhouse gas emissions per tonne of cement since 2014, aided by the use of alternative fuels and investment in energy efficiency. The Korean government now requires that greenhouse gases be cut by 12% by 2023 from 2018 levels by 53% by 2050.
The industry currently uses post-consumer plastics as fuels instead of fossil fuels and incorporates byproducts from other industries, like sludge. However, some environmental groups have labelled cement made from industrial byproducts as ‘garbage cement’ claiming it contains hexavalent chromium levels more than four times the EU’s allowable limits. The use of plastics as alternative fuel has also sparked complaints from local waste collection and incineration companies, who argue that cement companies are taking away their business.
Professor Kim Jin-man from Kongju National University said "We also need to focus on developing high-performance clinker, advanced chemical admixtures for concrete, and accelerators that shorten concrete curing times."
India: The Jaipur Heritage Municipal Corporation has successfully converted around 6000kg of seized single-use plastic into a revenue-generating resource by selling it to cement plants. The plastic was collected over the past three to four months from local markets as part of an anti-plastic campaign, according to the Press Trust of India.
Commissioner Abhishek Surana said "Disposal of the seized single-use plastic was a major issue. We assessed that a supply chain exists in the system and installed refuse derived fuel machines at dumping yards to shred the plastic and sell it to cement manufacturing plants. It has also started generating revenue for the corporation."
Taiwan: Asia Cement Corporation tested its waste wind turbine blade processing capacities using 12t of blades earlier in November 2023. The cement producer had previously processed 9t of waste turbine blades for use in its plants up to the end of October 2023. Asia Cement Corporation says that the waste consists of fibre-reinforced plastic (FRP), which is 60% silicon dioxide, calcium oxide and aluminium oxide and 40% polyester. The polyester can replace fossil fuels as alternative fuel (AF) for cement plants, while the other chemical compounds can serve as supplementary cementitious materials (SCMs).
European Union eases up on sustainable packaging
23 November 2023Europe: The European Parliament voted in favour of multiple amendments to the European Commission’s Packaging and Packaging Waste Regulation (PPWR) on 22 November 2023. The amendments remove, modify or make non-binding the PPWR’s 2040 reuse targets. Meanwhile, 2030 targets were made adjustable to recycling rates. Total packaging volumes are still required to drop by 5% by 2030 and by 15% by 2040 in each member state.
Sustainability lobbying organisation Environmental Coalition on Standards (ECOS) described the introduction of recycling rates into a lower schema of waste targets as ‘comparing apples with pears.’ ECOS attributed the amendments to a ‘barrage’ of false claims, scaremongering and lobbying from industry players.
ECOS programme manager Mathias Falkenberg said “This decision will not sufficiently address rising plastic and packaging waste or the pollution crisis. The European Parliament has just weakened a perfectly feasible solution to tackle throwaway culture without offering an alternative. It is very frustrating that the European Commission’s progressive prevention and reuse agenda has not received full support from the Parliament today.”
ECOS founded the Alliance for Low-Carbon Cement & Concrete (ALCCC), an association of companies focused on alternative building materials production, in May 2023.
Nuvoco Vistas commissions alternative fuel feeding systems at Nimbol and Risda cement plants
23 June 2023India: Nuvoco Vistas has commissioned feeding systems for alternative fuel (AF) in the pyro-process sections of its Nimbol and Risda cement plants. The systems will handle municipal solid waste, including unrecyclable plastic.
Managing director Jayakumar Krishnaswamy said "As part of our Protect Our Planet agenda, we view the AF projects as an important step towards fulfilling our commitment to sustainable cement manufacturing and reducing the environmental impacts. The successful completion of this project demonstrates our commitment to reducing carbon emissions, maximising waste consumption and demonstrating responsible resource management practices.” He added "This along with, other themes under Protect Our Planet agenda, is enabling Nuvoco to build robust partnerships with several stakeholders, and contribute to society at large.”
Republic Cement and Ecoloop seek new waste management partners
30 January 2023Philippines: 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.”
Cemex opens Tunjuelo Circularity Centre
13 December 2022Colombia: Cemex has announced the launch of the Tunjuelo Circularity Centre at its former Tunjuelo quarry near Bogotá. Having rebuilt parts of the 50m-deep quarry with demolition waste, Cemex will now work on its ecological restoration, while continuing to receive excavation waste for reconstruction of the ground. It will meanwhile divert demolition waste deliveries for recycling in aggregate production. In Bogotá, Cemex has launched an initiative for urban construction partnerships in collaboration with local authorities. It will also collect municipal solid waste (MSW) there for use in its cement production and collect its used plastic cement bags for recycling in building materials production.
Cemex’s Colombia and Peru president Alejandro Ramírez said "This is a pioneering model for Cemex in the construction materials industry globally, which we aim to position as a benchmark for circularity within the sustainable development of large cities in Colombia and the world. A piece of land that supplied materials for Bogotá's development for decades has received construction and demolition waste for its redevelopment and was transformed into a green area to the south of the city, an epicenter of the circular economy and an opportunity for urban development for the capital city of Colombia."
Philippines: Republic Cement is supporting efforts to remove plastic pollution from the sea by co-processing the waste in its cement production. The Business Mirror newspaper has reported that the cement producer has partnered with plastic waste collector Pure Oceans to take delivery of shipments cleaned up from off the coasts of Batangas and Davao.
Republic Cement chief executive officer Roman Menz said "Republic Cement is proud to partner with organisations such as Pure Oceans. Their deep commitment towards safeguarding the environment, while making significant contributions to the Philippine plastic waste crisis, is an inspiration for us to continue doing what we do in order to make a tangible impact on our communities, towards building a greener and stronger republic."
Through its partnerships with local fishing communities, Pure Oceans diverted 1.93m bags of plastic waste over the three years prior to the start of October 2022.
Plastic neutrality for Republic Cement
07 September 2022Philippines: Republic Cement has announced that it has become plastic neutral, thanks to the continued efforts of its Ecoloop subsidiary. By collecting and co-processing the equivalent volume of residual plastic waste as it has used in the packaging and transport of its cement products, Republic Cement was able to offset its plastic packaging footprint for 2020, 2021 and so far in 2022. This is equivalent to over 890 dump trucks filled with plastic waste. Ecoloop has already helped a number of other companies to reach plastic neutrality.
