Sustainable Construction Products 10

•M-LS

• Circular economy

• End of waste

• Carbon negative product (PAS 2050)

• CE certification (BS EN 13055 & 13242)

• BES 6001

• Competitive

• Consistent / Adjustable

•Multiple applications

Technical Challenges 11

• From research to commercial operation

•Chemistry to concept engineering design to operational engineering efficiency – IPR on innovation on engineering as a result

•Waste streams highly variable – IPR on mix designs formulation with carbonation

•Wide scope of technical knowledge skills from ash chemistry to recycled aggregate applications

•Understanding of linking the technical work to produce a marketable recycled aggregate

Barriers 12

•Environmental legislative policies e.g. “ EU - End of Waste” is interpreted differently for each country.

•Market acceptance – regulations/BAT

•Perception / conservative attitude

•Multiple/diverse regulations/guidance “bridge the gap”

•Zero price point for green products

•Competitive behaviour from less technical solutions for disposal of ashes (e.g. landfill)

Possibilities 13

•Production and capturing large volumes of technical data to support our technology

•Corporate responsibilities

• International collaborations

•Waste hierarchy (EfW increase, landfill decrease)

Policy Measures 14

•Governmental and global policies

•Reliance and acceptance of landfill

•Policies for “recycled materials standards”

•Harmonised EoW concept and regulation not well developed globally

•Need positive benefits for permanent carbon capture technologies linked to carbon trading

Summary 15

•Treatment & recycling of thermal residues and a wide variety of industrial materials

•Manufacture a carbon negative limestone aggregate

•Technical challenge of commercial realization

•Barriers from market adoption and competition

•Possibilities from changing commercial responsibility and waste hierarchy shift

•Policy changes to facilitate waste valorisation
