Some facts and figures

UK uses around 5 million sheets of plywood per year for temporary works Bovis Lend Lease require plywood to be certified under the Forest

Stewardship Council (FSC) Most FSC plywood is transported long distances UK generates over 5 million tonnes of plastic per year, landfill running out 80% of plastic waste is incinerated or dumped as landfill Recycling usually involves sorting and segregation

£1400 “wasted” per builders’ skip The average skip costs £200. The average cost of what is being thrown

away in that skip is over £1,200 (Source: WWW.CIRIA.ORG).

Powder Impression Moulding (PIM) process

3DM developed and own the rights to PIM Dirty co-mingled waste plastic can be used to produce products with up to

95% recycling Pilot plant built at Caerphilly to enable protoyping of new products

Bulk arrives Material sterilised Powder/granules

Opportunities in construction

Identified temporary works uses in construction

First stage a straight replacement for ply

Opportunity to run trials at St David’s 2, Cardiff, a £300m retail development for St David’s Partnership (Land Securities and Capital Shopping Centres)

3 way investment in moulds St David’s Partnership, Bovis Lend Lease and 3DM

Initial requirement to be self coloured, graffitti resistant, non flammable

So what does it look like?

What is it like to handle?

Finishing touches

Use in concrete formwork

How green is the board

Plywood hoarding panel = 23 Kg CO2

Mixed recycled PIM panel = 21Kg CO2

Potentially more uses of PIM panels

Note above figures are extremely positive given that generally recycling is seen as energy intensive.

Source of embodied energy coefficients – Centre for Building Performance Research, Wellington (NZ)

Assumes shipping of ply from South America

Assumes transport within UK by container truck

The Way forward

Research project with Brunel University – establish the effect of the range of plastics and the properties of the board

Obtain BBA certificate to enable uses in permanent works to be explored

Establish larger volume production facility

Explore other additives such as Titanium dioxide

Develop hoarding panels with integrally moulded rails and posts

Trial further applications – BPB Gypsum

Future

Eco-board - further testing, trials and development – 2007Commercial production with Express plastic and recycling – 2008
