Poland: Sweden’s NextFuel AB plans to launch NextFuel, a briquette fuel made from elephant grass, at the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24) taking place in Katowice. The company says that its product is cheaper than and oil and coal in most markets and could be used to replace some or all of the coal normally used by a cement plant, coal plant or a steel plant. Its first operational plant is based in Austria.

The first NextFuel project is expected to reduce the CO₂ footprint of a cement factory in East Africa by 105% compared to the coal it is using at present. The cement plant also expects to cut its energy costs in half by using NextFuel instead of coal imported from South Africa. It will be able to grow Elephant Grass, the source of the fuel, next to the plant to reduce its fuel transportation costs.

Elephant Grass is a perennial tropical plant that can produce several crops in a year. Once the grass has been harvested, NextFuel says its technology requires ‘very little’ energy to produce a briquette. The company asserts that due to a quick carbon cycle and the storage of carbon, less CO₂ is released into the atmosphere when the fuel is burned than was captured from the atmosphere a few months earlier when the grass was growing. NextFuel says that annually the carbon cycle becomes negative.

After the grass is harvested, it is dried and fed into a patented reactor. This is a rotary drum, indirectly heated and operated with a low oxygen atmosphere. While inside that drum, volatile elements are separated from the grass, and the physical properties together with the energy content are transformed in less than 30 minutes. The reactor also drives out the off-gases from the grass. They are used as surplus energy to produce heat or electricity to power the facility. After the reactor is finished, the fuel is densified and turned into briquettes that are cooled. These briquettes are ready to use directly as a CO₂ negative fossil fuel substitute both in industrial and electricity production.

NextFuel plans to scale by licensing its technology to companies all around the world.

India: The Cement Manufacturers Association (CMA) is considering using agricultural biomass as an alternative fuel. It says it is willing to offer support to different state governments to help find a way of delivering biomass directly from fields to cement producers, according to the Times of India newspaper. The CMA says it is offering a solution to the dust pollution caused by crop burning. However, the industry needs to resolves problems with transportation and seasonality. The CMA hopes to contact local governments and organisations to find a solution to these issues in 2019.

Oman: Four French investors and technology suppliers, including Fives and Suez, have created a syndicate to develop business opportunities in the Special Economic Zone Authority of Duqm. The other partners are CMA CGM and EDF Renewables. The companies intend to assess various investment options in the area and develop them. In particular, the syndicate has an interest in a ‘global approach to cement factory ecosystems’ and related facilities including transport facilities, a solar power generation plant and the production of alternative fuels.

France: Vicat has showcased Vicat Circulère, its construction waste management plant, at the Pollutec environmental exhibition in Lyon. The building materials producer has set itself the goal of no longer using fossil fuels at its cement plants by 2023. At present it has an alternative fuels substitution rate of over 50% at its cement plants in France.

France: Geocycle France says it has strengthened its local presence by setting up a network of six units at LafargeHolcim sites in 2018. These are: La Malle, Le Teil, Martres, Saint -Pierre-La-Cour, Altkirch and Val d'Azergues. The Geocycle units are intended to support co-processing activity at cement plants. In 2017 the French waste management subsidiary of LafargeHolcim recycled 0.65Mt/yr of waste materials.
