South Africa’s carbon tax: an opportunity for eco-cements

On 26 May 2019, President Cyril Ramaphosa signed off South Africa’s Carbon Tax Act, which came into effect on 1 June. The financial impact on South Africa’s cement sector should intensify carbon emission reduction programmes and accelerate the trend towards the production of eco-blended cements, but it could also have a negative effect of encouraging cheaper imports.

In this first phase, a tax of ZAR120/t (US$8/t) of CO2 emitted will be in place. However, polluters receive 60-95 per cent of carbon allowances free, bringing the effective penalty down to ZAR6-48/t. Following a review of these rates, phase two of the country’s carbon tax programme will run between 2023-30. Further greenhouse gases (GHG) being taxed include methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

South Africa’s carbon tax is directed at some 1000-1500 companies and 75 per cent of national emissions. The cement sector is a small part of this target reach, as it accounts for just one per cent of the country’s GHG, according to the Association of Cementitious Material Producers.

South Africa’s Treasury estimates that the tax will produce revenue of ZAR1.8bn (US$120m) in FY19-20, which is minimised by the offsets in the first period. More importantly, the initiative ties South Africa to the Paris Agreement by committing to cut emissions by almost 50 per cnet by 2030 (to between 398-614Mt of CO2) in line with targets to limit global temperature rises to below 1.5˚C.

Cement industry response With such a measure having a direct effect on the county’s cement industry, it could be expected that the response would be negative. But for AfriSam, this is not the case.

The cement company has been proactively participating in the legislation and has interacted with the Department of Environmental Affairs and Treasury on the design of the Act. The medium-term objectives for AfriSam are positive in that there will be a drive towards implementing carbon reduction projects and blended cements. The cement producer also forsees a change in the way cement is viewed by customers, now that a tax has been put in place, and a need to be transparent on pricing to help customers make more informed and ‘greener’ choices. “We are taking a transparent and responsible approach to the new tax,” says Richard Tomes, AfriSam’s sales and marketing executive. “By showing the amount of carbon tax payable on each specific bag of cement, our customers will still see the base price that we are charging.

This avoids any confusion about how much of the final price is going toward the tax. “We believe that a tax should not just be a punitive tool, but it should also affect behaviour in society. Just as cement producers are working hard to reduce carbon emissions, so the end-user can also play their part by choosing an environmentally-friendly brand.” It is not yet clear how other domestic players such as PPC, Sephaku Cement (Dangote), Natal Portland Cement (Intercement), Mamba Cement and LafargeHolcim will respond to the carbon tax, but it is likely that they will also be looking to pass some costs on to the end-user and do more to promote eco-blend cements, such as fly ash and slag cements. This could be the start of a significant change.

The Industrial Policy Action Plan (IPAP) estimates that the Presidential Infrastructure Coordinating Committee (PICC) and Department of Trade and Industry (DTI) are planning about ZAR469bn in construction programmes between 2013-23. These should offer plenty of opportunity to switch to eco-blend cements when implementing these initiatives, which could serve as flagship projects for these ‘greener’ cements. In meeting this demand, the cement industry could supply eco-blend cements and lower the sector’s carbon emissions. With lower liabilities for carbon emissions of eco-cements would also enable space for producers to trade carbon credits and create another revenue scheme, suggest industry analysts Baker McKenzie. The lines are still being drawn Despite the positive outlook that environmental benefits might bring with the new tax, South Africa’s cement manufacturers will need to know if funds from the tax will be ring-fenced to assist them to implement further GHG emission reduction programmes.

The industry is also aware that importers are not subject to the carbon tax. This could have a detrimental impact on the domestic cement producers, says Hannes Meyer, AfriSam’s cementitious executive. But environmentalists are expected to make further demands to limit emissions. South Africa’s Carbon Tax has taken almost a decade to implement and now that some progress has been made environmentalists will push for more. “We commend the president for putting wheels to this long overdue issue,” said Morné du Plessis, head of WWF South Africa. “During the second phase, we will have to ramp up our transition ambitions significantly.”

UK: Lafarge Cement, part of the Aggregate Industries business, has introduced Rapid Set Cement to its packed product range. It is an Ordinary Portland Cement containing calcium aluminate for rapid hardening. The product is designed for use in screeds and renders to prepare wall and floor surfaces prior to installing most tile types. It’s suitable for dry and wet installations, including swimming pools, and can be pumped for fast application. It is available in 25kg paper bags and is a quality-assured BS EN 197-1 CEM II, cement carrying CE marking.

US: Grupo Cementos de Chihuahua (GCC) says that the upgrade to its Rapid City cement plant in South Dakota has started operation. The expansion has added 0.44Mt/yr of production capacity to the unit taking its total capacity to 1.18Mt/yr. The project cost US$105m and it started in 2016. Tie-in of the upgrade was finished in late November 2018. Production was suspended during the tie-in-process and has now resumed. The new facilities are now being stabilised.

“The Rapid City expansion comes at an opportune time, as our US cement plants are running nearly at full capacity, and we expect to see continued, steady growth in demand across our market area.

We will be able to serve our customers better and operate our cement logistics network more efficiently with the additional capacity,” said Enrique Escalante, GCC’s chief executive officer (CEO).

GCC has 5.8Mt/yr of cement production capacity. Of this, 3.5Mt/yr is in the US, with plants in Pueblo in Colorado, Odessa in Texas, Tijeras in New Mexico, Trident in Montana and Rapid City in South Dakota. GCC expects to ramp up the new production capacity at Rapid City gradually over the next 18 to 24 months, in accordance with market conditions.

GCC’s cement production capacity in Mexico is 2.3Mt/yr from plants in Chihuahua, Juarez and Samalayuca in Chihuahua state. In the third quarter of 2018, GCC reactivated two idled kilns in Chihuahua to increase production of both oil well cement and construction cement.

Argentina: Aumund Brazil and Aumund China have collaborated with Sinoma Tianjin TDI to supply two clinker-conveying orders for cement plants. No value for either order has been disclosed.

Aumund will supply three chain bucket elevators, eight belt bucket elevators, five pan conveyors and a drag chain conveyor for Line 2 at Loma Negra’s L’Amali cement plant. The order also includes 19 silo discharge gates.

In August 2017 Loma Negra awarded Aumund the order to build a second kiln line with a capacity of 5800t/day at the L’Amali plant in Olavarria in Buenos Aires province. The new line, which will produce 2.7Mt/yr of clinker, will be located adjacent to the existing kiln line. Production will start early in 2020.

In June 2018 Aumund Brazil worked with Aumund Brazil and Sinoma to supply four belt bucket elevators, three chain bucket elevators and three pan conveyors via Sinoma TDI to Cementos Avellaneda. Cementos Avellaneda is a joint venture operated by Brazil’s Votorantim Group and Spain’s Cementos Molins.
