Business are seeing Zero Landfill status as a benefit to the business and valued by customers.

DuPont’s Business Innovations business has achieved zero landfill status.  Three years into the effort Business Innovations “ … has become completely landfill-free, reducing its environmental footprint from 81 million pounds of landfill waste annually to zero.”

15 locations around the globe were included in this effort and materials “ …even cafeteria waste were all within scope …”

Materials that previously were landfilled are now … repurposed (cafeteria waste becomes energy), recycled (Tyvek® scraps),  or reused (pallets are reused to ship goods or to make animal bedding).

No waste from the production of Corian® , Zodiaq®, Tyvek® or geosynthetic textiles is landfilled.

Dupont sees photovoltaic sales improve ahead of expectations and bumps up its near term revenue objective.  …

... "DuPont now expects its sales into photovoltaics to exceed $1 billion in 2011, which is a year ahead of plan, and has set a new goal to exceed $2 billion in sales by 2014.

In 2009, DuPont sales to the photovoltaic market exceeded $550 million - an increase of over 25 percent from the previous year - and outperformed the broader industry, which experienced significantly lower growth, estimated to be 10 percent or less. DuPont’s growth is supported by new innovations that improve module efficiency and lifetime, and enable new photovoltaic technologies and applications, which ultimately accelerate the industry’s drive to bring costs down in line with other forms of energy.
DuPont materials and technology solutions are designed to help increase the efficiency and lifetime of crystalline silicon and thin film photovoltaic solar modules, while reducing total systems cost and enabling the photovoltaic industry to reach grid parity faster. " ...

... "Photovoltaic metallization pastes are screen printed onto the surface of solar cells in a pattern of grid lines which serve to collect electricity produced by the cell and transport it out. To maximize efficiency in the solar cell, the multiple printing technology will reduce the shadowing effect of wide grid lines on solar cells and improve electrical conductivity. Applied Baccini Esatto Technology together with DuPont Solamet photovoltaic metallization pastes enables narrower and taller grid lines to be precisely printed in two or more layers. In addition to demanding precise alignment of the patterning system, multiple printing requires the paste to be finely tuned to perform consistently during all printing passes. " ...

... "The M-25 design was modified to further reduce weight and extend performance. The M-25 standard design, when worn by soldiers in the field for extended missions, is up to 80 percent lighter than conventional power sources, yet capable of powering a wide range of soldier equipment, such as digital communication and navigation equipment. In addition to its light weight, the M-25 delivers quiet and continuous energy, and offers independent standalone functions such as remote area battery charging and power. The M-25 has the capability to revolutionize wearable portable power sources by extending soldier mission times to 72 hours or more. " ...
