H+H is committed to actively tackling the environmental issues related to its operations, including ways of avoiding, containing or remedying any adverse environmental impacts. For example, H+H always takes into account environmental considerations such as reducing the consumption of raw materials and energy when building new factories or upgrading existing factories.
Looking forward, H+H will regularly seek to improve resource and environmental awareness amongst its employees, partly by trying to ensure that decision-makers in H+H always take into account any environmental consequences relating to the use and disposal of a given product before deciding to procure that product.
Aircrete is based on water, sand or pulverised fuel ash, lime and cement. The production of aircrete thus does not include any scarce natural resources. To save water resources, some of H+H's existing factories collect rainwater for use in production, and production water is reused to some extent.
The machinery used for manufacturing aircrete is electrically powered, and gas is used for raising steam for autoclaving the aircrete. H+H continuously strives to minimise its electricity and gas consumption in order to reduce its energy consumption and consequently its production costs and CO2 emissions, and H+H regularly explores the possibilities for using renewable, more sustainable energy sources.
On demolition of buildings incorporating aircrete, the aircrete can be reused in crushed form for applications such as road fill, insulation material and material for lightweight aggregate concrete.
Lastly, as part of its product development, H+H continuously seeks to enhance the insulating properties of its aircrete products to ensure that aircrete remains one of the most energy-efficient materials for wall construction.
