Throughout the entire product life cycle – from cradle to cradle – Troldtekt focuses on minimising the environmental impact of its products, and on optimising resource consumption and processes so that the products add value. This is the line of thought in the product life cycle which underpins Troldtekt’s Cradle to Cradle business strategy.
The natural option
Troldtekt cement-bonded wood wool panels are made of 100 % natural materials: Wood and cement. Troldtekt uses Norway spruce grown in Denmark which is PEFC™ or FSC® certified. Both certification schemes ensure that the wood comes from responsibly managed forests. The production of Troldtekt panels uses only cement from Aalborg Portland, which extracts the raw materials from the Danish bedrock with minimal environmental impact. Chalk and sand are the key raw materials used to make Portland cement. Both chalk and sand is extracted in Denmark, where sand dredging helps keep sailing channels navigable.
Troldtekt has been manufacturing cement-bonded wood wool panels in Troldhede in western Denmark since 1935. The production of Troldtekt panels takes place under modern conditions in a closed system without any waste water discharge. About 95% of the energy consumption for heating production derives from CO2-neutral wood fuel left over from production.
Troldtekt is a DONG Energy climate partner, so all electricity used to produce Troldtekt panels derives from wind power.
Troldtekt panels contain no harmful substances or allergens and have qualified for the best Danish Indoor Climate Labelling categories. Troldtekt panels are also recognised as a hypoallergenic product by Allergy UK, and labelled in the lowest emissions class (M1) by the Finnish Indoor Air Association and the Building Information Foundation RTS.
Troldtekt cement-bonded wood wool panels can be composted and returned to nature as a soil conditioner.
The cement in Troldtekt’s acoustic panels boosts oxygen levels during the composting process, while the wood adds organic material to the compost.
Like production waste, clean Troldtekt waste from building sites in the form of offcuts and waste from
Troldtekt acoustic panels can be safely returned to nature as soil conditioner. Cement-bonded wood wool demolition waste can instead be recirculated in the production process as a raw material in new cement. Cement manufacture is a thermal process which renders any surface treatment harmless. The wood content of the cement-bonded wood wool panels contributes to the combustion process (energy), while the cement component becomes a raw material in new cement.
