Encouraging news from Egypt with the announcement that Lafarge Ecocem has taken on two refuse-derived fuels (RDF) contracts in Suez and Qalyubeya. The RDF plants will have production capacities of 42,000t/yr and 280,000t/yr respectively, after upgrades are built.

The move follows a deal Lafarge struck with Orascom in March 2015 to develop a waste management framework of municipal and agricultural waste. The plan is to achieve an average fuel substitution rate of 25% by the end of 2015. Around the same time Ecocem also signed a cooperation agreement with the German Development Cooperation (GIZ) and the Qalyubeya Governorate to upgrade a recycling plant in Qalyubeya to produce RDF. Part of the deal was intended to reinvest some of the revenue from RDF sales back into the region's waste collection infrastructure.

These production levels compare to SITA UK's new RDF plants in the UK, which has a more mature RDF market. There, the newly opened Malpass Farm plant is planned to produce 200,000t/yr and the Tilbury plant will have an output capacity of 500,000t/yr when it opens. However, the Malpass Farm plant mainly feeds one cement plant, the 1.3Mt/yr Cemex Rugby plant with a mean substitution rate of 61% in 2013. By contrast, Lafarge Cement Egypt runs the massive 10.6Mt/yr El Sokhna plant.

Co-processing at El Sokhna by Lafarge is of particular interest given the links with Egypt's unofficial household waste collectors, the Zabbaleen. Lafarge Egypt recruited and trained 140 Zabbaleen to gather waste material for RDF production. The strategy enabled Lafarge to gather continuous supplies of RDF and strengthen local stakeholder relations, as Lafarge's 2013 sustainability report puts it. Lafarge Egypt's substitution rate was 2.2% in 2012 with significant improvements made since then. The current target of 25% for the end of 2015 shows how much progress Lafarge has made.

Hisham Sherif of the Egyptian Company for Solid Waste Recycling (Ecaru) placed Egypt's municipal solid waste level at 20Mt/yr at a presentation given at the Global CemFuels Conference earlier in 2015. From this 4Mt/yr of RDF could be produced. Together with biomass derived fuel (BDF) Sherif reckoned that the country's cement plants could reach substitution rates of 30 – 40%. Problems though with increasing RDF rates in Egypt include legal complexities, institutional issues, poor services and monitoring and centralised planning with little regard for the country's unofficial waste pickers, such as the Zabaleen.

Lafarge Ecocem appears to be tackling each of these problems in turn as the deals with Orascom and the Qalyubeya Governorate show. However, spare a thought for Egypt's unofficial waste sector workers who are likely to lose their livelihoods as waste management becomes more formalised and personnel rates per tonne of waste collected tumble.

CRH's ambitions took a setback this week when the Irish Competition and Consumer Protection Commission (CCPC) raided the offices of its subsidiary Irish Cement as part of an investigation into the bagged-cement industry in Ireland. Details are vague but the media reports state that the inquiry is examining whether or not the Irish market leader has abused its dominant position in the market, valued at Euro50m/yr.

Undoubtedly CRH and Irish Cement hold a leading place in the local cement industry. Irish Cement runs two integrated cement plants in the Republic with a combined production capacity of 2.7Mt/yr. This constitutes 79% of the country's 3.4t/yr total capacity.

Previous acquisition activity such as CRH's purchase of Dudman Group's UK import terminals in July 2013 has led to concerns regarding market competition. At that time Irish cement importer Eircem complained to the UK Competition Commission (CC), claiming that 'there is no free competition' in the market and also to initiate proceedings against CRH for damages relating to alleged anti-competitive behaviour in that market.

Roll the clock forward nearly two years and CRH is making the headlines once more for a much larger acquisition portfolio: the purchase of the largest chunk of assets sold from the merger of Lafarge and Hocim. With regards to Ireland and the UK, CRH will take on three (Dunbar, Tunstead and Aberthaw) of Lafarge Tarmac's five cement plants. Lafarge Tarmac's other two plants (Cookstown and Cauldon) will become part of the Aggregate Industries division of Lafarge Holcim. And once again, following acquisition activity competition, questions are looming as the CCPC raid suggests. This time though the potential impact of any market abuse, if it is actually happening, is far larger given the influx of UK and European assets that CRH are taking on.

We don't know what the CCPC will find but we can look at how CRH was viewed in the UK CC report on 'Aggregates, cement and ready-mix concrete market investigation' published in January 2014. At that time the CC concluded that, "We have seen nothing to suggest... that the recent acquisitions by CRH will result in importers collectively or individually offering a significantly greater constraint on cement producers than in the past." Amusingly though CRH also told the CC that it had no major expansion plants for the UK.

We also know how one of CRH's competitors felt about them. One of the more telling quotations from the CC report was from a Commercial Manager, at Lafarge Cement Ireland who viewed expansion in Ireland by Lafarge as a 'mechanism' to control CRH's ambitions by attacking it in its home market by showing CRH that Lafarge was a global player. Ironically the comments of that anonymous manager look very different now that CRH is on track to becoming a global player itself.

There was a lot of news out of Lafarge and Holcim this week regarding preparations towards their merger. Just this morning we heard that the partners have entered into a binding agreement with Ireland's CRH regarding the sale of the assets that must be divested. Meanwhile, Lafarge and Holcim have also completed the appointments for the future LafargeHolcim executive committee. Its nine members will be responsible for such tasks as finance, integration, performance and costs, growth and innovation, as well as regional activities in Europe, Asia Pacific, the Middle East and Africa, North America and Latin America.

However, it was other types of personnel that featured in Lafarge and Holcim's earlier press releases. On 19 May 2015 Lafarge came out and announced the first (pre-merger) job losses that will result from the merger. It will cut 380 positions in central and regional corporate roles, with 166 going in its native France. For its part Holcim will make 120 pre-merger job losses, all in Switzerland. Ignoring the clear discrepancy in scale between the different sides, Lafarge and Holcim will have lost at least 500 jobs out of their combined ~130,000. This is just a scratch on the surface, but it does raise an interesting question: How many more jobs will go at LafargeHolcim?

First up are the staff that will go to work for CRH. This probably represents the largest number of staff that will come of LafargeHolcim's books relative to Lafarge and Holcim's current staff levels. According to their 2014 Annual Reports, Lafarge and Holcim employ a combined 81,000 staff in cement roles. Given that they have a combined 425Mt/yr of cement capacity (give or take) this equates to around 190 staff for each 1Mt/yr of capacity.

As the new LafargeHolcim will have control over around 340Mt/yr of cement capacity, we can crudely scale the 190 staff up to 64,600 cement sector staff. This indicates that around 16,400 staff that are currently employed by Lafarge and Holcim will be 'off' to CRH (and others). This leaves 48,100 staff in non-cement roles at LafargeHolcim.

Will more jobs be lost post-merger? Lafarge and Holcim have stated that the new entity will have 115,000 staff. However, with around 42% of future employees employed in non-cement roles - compared to 41% and 34% for Lafarge and Holcim respectively in 2014 - it certainly seems that there could be scope for at least some reduction in overall numbers from LafargeHolcim's non-cement functions. Future job losses could therefore be a possibility, but the exact scale of future consolidations and 'synergies' (if any) will only become apparent post-merger. Maybe LafargeHolcim could end up with around 105,000 to 110,000 staff.

A key time may well be early 2016, when LafargeHolcim will launch a new 'corporate structure.' This term was also used by Lafarge and Holcim in their most recent releases, so further job losses could be on the cards.

One member of LafargeHolcim staff with nothing to worry about now will be Bruno Lafont, current CEO of Lafarge. He received a Euro2.5m bonus this week for his 'key role' in conducting the merger. How LafargeHolcim staff who could be nervous about their jobs will take this remains to be seen.

At the 24th AFCM Technical Symposium in April 2015, Nguyen Quoc Thang, plant manager at Vicem's Binh Phuoc cement plant, delivered an outstanding presentation. He explained the sourcing and processing methods for using cashew nut shells as an alternative fuel to replace coal at the plant.

Around 300,000t/yr of cashews are grown and harvested in the south-east of Vietnam, the equivalent of about 130,000t/yr of cashew nut shell, 85% of which remains after processing. According to Nguyen Quoc Thang, the plant uses cashew nut shells to replace 35% of its fuel and has significantly reduced its CO2 emissions and fuel costs by doing so.

Cashew nuts are grown in large quantities in Brazil, India, Nigeria, Vietnam, the Ivory Coast, Pakistan and Indonesia, among others. In 2012, some 4.15Mt of cashew nuts were grown. Cashew nut demand has risen greatly in both the long-term and the more recent past. New (and delicious) products are being designed to meet the demands of health-conscious people and vegans, including cashew nut butters, cashew milks, cashew cream, cashew ice cream, cashew cheese and cashew cooking sauces. All at premium prices, of course, and all driving cashew nut demand ever-higher.

Cashew nuts are always sold pre-shelled, as the shell is toxic if consumed. Their growing production volumes and the necessity that they always be pre-shelled for sale or further processing makes cashew nuts an ideal alternative fuel for cement production, with reliable supplies guaranteed for the foreseeable future, subject to good crop yields. Moreover, cashew nuts are mainly grown in regions that currently have low cement plant alternative fuel substitution rates, providing an instant solution to some of the cement industry's environmental challenges.

Cement producers in cashew nut-growing (and other types of nut) countries would do well to note the example that Vicem's Binh Phuoc cement plant has presented. In addition to saving costs and tackling environmental restrictions, the highly-profitable nut industries could provide extra economic value to their home countries through partnership with local cement plants.
