India: Dalmia Bharat has accelerated its commitment to net zero CO₂ cement production by 2040 with the launch of its newTransformative and Collaborative Strategy Roadmap. The roadmap provides a framework forinnovation, growth and sustainability initiatives through shared synergies with private and public entities, including Asian Development Bank and 50 local government authorities. Initiatives already underway include non-recyclable waste disposal partnerships with local administrations across India. Dalmia Bharat is supporting these initiatives with the installation of chlorine dust bypass systems at two of its cement plants, the first in India. The producer's cement operations are already 40% renewably powered and 13 times water positive.

Dalmia Bharat's environmental, social and governance (ESG) executive director and chief risk officer Arvind Bodhankar said “As a cement producer, we are attached to people’s happiness by gluing thousands of dreams into reality. We therefore strive to give our customers only the best building materials with the lowest environmental impact. In addition, we also intend to drive a net-zero emissions reality with a strategy that’s aligned with our business philosophy, Clean and Green is Profitable and Sustainable.”

Australia: Boral plans to install chlorine bypass technology at its Berrima cement plant in New South Wales. The Illawara Mercury newspaper has reported that the installation will help the plant to double its alternative fuel (AF) substitution rate to 100%. This is one of the ways in which the producer aims to reduce its Scope One and Two emissions by 46% between 2020 and 2030.

In mid-February 2022, Boral acquired new land at the site of its Dunmore quarry, also in New South Wales.

Switzerland: A TEC has secured a contract to install a new ReduChlor chlorine bypass system at Holcim Schweiz’s Eclépens cement plant in Vaud. The supplier says that it will also fit a bypass dust handling system and upgrade the alternative fuel (AF) feeding system at the plant.

Portugal: Denmark-based FLSmidth has won a contract to supply a chlorine bypass system to Cimpor’s Souselas cement plant. The aim is to eliminate chlorine build-up in the plant’s flue gas after the company increases its refuse-derived fuel (RDF) usage rate to 60%. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022. No value for the order has been disclosed.

Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO₂ emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”

Hungary: Lafarge Cement Hungary has announced plans to upgrade clinker production at its 1.0Mt/yr Kiralyagyháza integrated plant with a Euro1.79m investment in chlorine bypass technology, which uses powdered limestone to remove chlorine and one tenth of the carbon dioxide (CO₂) from gases released in clinker production, which will then be used in clinker cooling. There will be a concomitant increase in the rate of alternative fuel (AF) substitution in the plant’s kilns, with an AF fuel store expansion in early 2020 set to raise AF usage to 80% from 60%.

Poland: LafargeHolcim has awarded a contract to A Tec to upgrade the chlorine bypass system at its Kujawy cement plant. A Tec will upgrade its existing Reduchlor bypass system to increase the rate to 10% from 5%. The upgrade will retain the system’s existing bypass filter and filter fan. The project will be commissioned in spring of 2017.

A Tec’s Reduchlor bypass system consists of a take-off chamber above the kiln inlet, specifically designed for each installation, and a specially designed quenching chamber, to which the chlorine condenses on and adheres to fine dust particles. After this condensation process the chlorine-enriched material is collected in a filter.
