World of Regions for Climate Conference & Exhibition, Paris 2014, opened by Arnold Schwarzenegger




Start-up company Novagg Limited were invited to exhibit their green lightweight aggregate at the recent World Summit of Regions for Climate in Paris this October 2014. Novagg is partnered by Climate-KIC the EU’s main climate change initiative and is pleased to have had the opportunity to demonstrate novagg® to a wide range of potential interested parties including ex-President of the Republic of Ireland Mary Robinson who now represents the UN as a Special Envoy for Climate Change.


Bert Bingham, Director of Novagg said “It was a privilege to meet Mrs Robinson and to be able to explain the environmental benefits of novagg® including how resource efficient it is as production takes waste that would normally go to landfill or worse exported for disposal in a less environmentally responsible manner and with a product that is the world’s greenest lightweight aggregate for use in sustainable construction”.


Novagg have proven the concept in successfully concluding a £1 million collaborative Research and Development project with world leading academic partners and are looking to raise funds to further develop the product, carry out more testing with major concrete manufacturers and to bring the product to market.

Novagg Limited has developed the world's greenest lightweight aggregate for use in construction, including in lightweight concrete. This was developed during a 3-year £1 million collaborative R&D project with Imperial College London part-funded by the UK Government’s Technology Strategy Board.


novagg®  is now partnered by Climate-KIC UK (KIC stands for knowledge information community) who are the European Union's main climate innovation initiative and Europe's largest public-private innovation partnership. Climate-KIC has nominated Novagg as the UK representative for the World Summit of Regions for Climate event in Paris on 10-11 October 2014.


Bert Bingham, Founder Director said “having proven the concept and successfully tested product from our pilot plant the recent involvement of Climate KIC has added new impetus to the project. We are really excited about the attention novagg® is receiving within the climate innovation start up sector and look forward to establishing the material as a global brand.”


novagg® is made from 98% waste diverted from landfill, principally mixed coloured cullet glass and industrial mineral wastes from the steel, aluminium, chemical, water and other sectors. The wastes are mixed, pelletised and then fired in a low temperature process using established rotary kiln technology. This bloats the pellets like popcorn (a fivefold volumetric expansion can be achieved) into a 'malteser-like' sphere full of small air bubbles which has light weight with strength.


The wastes, including hazardous wastes, are transformed in the process into a new and easy to use product. The novagg® material has the additional and market leading advantage of being very low in water adsorption which reduces water and cement requirement in the concrete mixtures, which has been described as the ‘holy grail’ of concrete technologists.


A leading industrial waste supplier has called novagg® the best solution to their waste disposal problem that they have found in ten years of looking and a major block-maker has described samples from the Stoke-on-Trent pilot plant as the best product they have tested in the last five years.


Waste producers and re-processors have the opportunity to share the benefit of reduced costs, lower environmental impact and carbon footprint, having their waste transformed into a ‘green’ product with enhanced corporate social responsibility performance.

Product can be engineered to customer requirements; lighter weight and lower strength for the non-structural block market and denser, stronger pellets for the structural pre-cast concrete market, which can be used in iconic high-rise buildings.


novagg® being lightweight with a closed pore and impermeable structure also demonstrates interesting thermal and acoustic insulating properties, with further evaluation planned.


The many advantages of lightweight aggregate concrete are well understood globally and future applications could include for example, lightweight concrete masts for offshore gravity base wind turbines. novagg® and related concrete products are fully recyclable and it is an ideal material for delivering resource efficiency and adding value at every stage in the circular economy.


In summary novagg® diverts waste from landfill, transforms hazardous waste into a benign product at a low temperature thus reducing primary energy input, creates a lightweight ‘honeycomb’ material (importantly with ultra-low water absorption) and is an extremely versatile material for use in the construction sector – increasingly important as UK demand is driven by BES 6001: Framework Standard for Responsible Sourcing of Construction Products.


novagg® are currently speaking to potential partners and investors from across the supply chain (waste producers, re-processors, mineral processors and customers) as we progress to full commercialisation. The concept is proven and product tested although there will be a short period of further development work.
