Holcim’s TectorPrint “ink”, designed for additive construction, is meant to print walls with the necessary structural integrity. Based on its project 3D printing a school in Malawi, Holcim claims that additive construction can cut the environmental footprint of a house by over 50 percent compared to traditional techniques. The walls can also be made in just 12 hours, which contrasts with the four days required with conventional methods. Jan Jenisch, CEO Holcim: “We are excited to be building one of the world’s largest 3D-printed affordable housing projects in Kenya. With today’s rapid urbanization, over three billion people are expected to need affordable housing by 2030. This issue is most acute in Africa, with countries like Kenya already facing an estimated shortage of two million houses. By deploying 3D printing, we can address this infrastructure gap at scale to increase living standards for all.” There are three home types in development, ranging from one-bedroom, 42-square-meter houses with a price of 2,436,000 Kenyan Shillings (~USD$21,600) to three-bedroom, 76-square-meter houses with a price of 4,484,000 KES (~USD$40,000).

However, despite its purported goals of sustainability through 3D printing, Holcim has a carbon footprint about the size of Venezuela . This is due to the fact that cement production releases significant carbon dioxide, representing eight percent of global CO2 emissions . The company may be attempting to make progress in the right direction, but it may be that its additive construction projects represent more of an attempt at greenwashing than anything else. After all, concrete is the foundation of its business and, like an oil company that derives its profits from fossil fuels, there’s no financial incentive for it to eliminate its primary business. The International Finance Corporation (IFC) that awarded Mvule Gardens an EDGE Advanced sustainable design certification for buildings that haven’t been constructed yet may not be that meaningful either. The World Bank’s IFC has been involved in REDD+ carbon trading schemes , which activists warn allows for companies and governments to protect or grow forests in one part of the world only to emit CO2 and cause environmental destruction elsewhere in ways that have a net negative impact on the planet. The story comes just days after news that the company would cooperate in an investigation into the possible role of Holcim’s Syrian subsidiary, La Farge SA, in complicity in crimes against humanity by paying armed groups like the Islamic State to protect its staff in the region. This came soon after news that a worker was killed and five more were injured at Marwar cement plant in India, owned by Holcim subsidiary Ambuja cement. 14Trees’ CDC Group also may not have the proper human rights cred, as it invested in the Feronia Inc’s oil palm plantations in the Democratic Republic of Congo, which was accused of human rights violations against local villagers. 3D printed buildings and other structures have the benefit of attracting a great deal of media attention that could play a role in drowning out any controversies that may be playing out.
