Cement plants of the future18 November 2013, Published under Cement NewsIn the first of a series of articles for ICR, Kline Consulting explores the impact that reducing carbon emissions could have on the design of cement plants of the future. The three traditional CO2 reduction levers – namely energy efficiency (fuel and power), fuel CO2 reduction and clinker substitution – will all be considered in detail, as will the role of carbon capture technologies. In this first article, the author focusses on clinker substitution and the changes that may be required to e... |
MSW co-processing in China24 October 2013, Published under Cement NewsAs large volumes of common waste increasingly present a problem, China’s search for effective ways of disposing of this waste is on. With new landfill options facing opposition and causing controversy, the co-processing of municipal solid wastes (MSW) is becoming an increasingly-attractive option. Following examples in other countries, China is now actively seeking to increase its MSW usage in cement kilns, with producers such as Huaxin Wuxue and Sinoma’s Liyang having taken up the challenge... |
India's waste win-win09 October 2013, Published under Cement NewsThe rapid growth of the Indian cement industry has seen the construction of many new efficient plants. The annual gains in output and supply to the market are clearly visible. However, further room for improvement still exists as the uptake of alternative fuels remains limited. Hazardous and municipal solid wastes offer a solution that not only solve some of India’s waste management issues, but also reduce the cement industry’s coal requirements and associated CO2 emissions.

Reporting value23 September 2013, Published under Cement NewsGlobalisation, international policy activity in response to crises and recession, current and future resource scarcity, environmental concerns and heightened expectations of corporate transparency and accountability have all pushed the boundaries of business reporting. Markets, regulators and civil society demand an ever-broader information requirement in which disconnected strands are brought together into a coherent whole and show how a company (or organisation) can add value now and in th... |

CCS in the EU cement industry10 September 2013, Published under Cement NewsOn 1 July 2013, the EU Zero Emissions Technology Platform (ZEP) – founded by the European Commission in 2005 to advise on research, policy and regulation for the promotion of carbon capture and storage (CCS) – published “CCS in EU energy-intensive industries”, a report on CCS in industries beyond the power sector. Emissions from the non-power sector made up 25 per cent of EU carbon emissions in 2010. CCS is for many of those industries the only available technology to cut emissions. The repo... |

The devil is in the detail04 September 2013, Published under Cement NewsThis year sees the start of Phase III of the EU Emissions Trading Scheme, which will run until 2020. The best-practice benchmark set for CO2 emissions has generated plenty of discussion. Cement industry expert Phil Kerton looks at some of the detail. The EU Emissions Trading Scheme’s Phase III and its benchmarks have generated much debate Some recent discussions on internet forums have taken up the question of best-practice benchmarks, in particular the EU Emissions Trading Sche... |
The strength of recycling23 August 2013, Published under Cement NewsOne of Latin America’s leading cement producers, Argos has been working on a pilot project for the collection, separation, classification and trituration of Construction and Demolition Waste (C&DW). The company has used recycled aggregates to partially replace conventional aggregates in concrete mixtures of different types of strength and settlement. Several lab tests were carried out to determine the effect of using recycled aggregates with results indicating that types of concretes contain... |
