Reducing Environmental Impact While Increasing Efficiency

Making A Positive Environmental Impact

At present, C.L.E.A.N. processes in excess of 30,000 liters of solvent from 1.2 million reusable wipers and blanket wash per week. Since this volume is composed of a mixture of various solvents, it’s impossible to determine exactly the volume of VOC gases intercepted before they reach the atmosphere. However, VOC levels in blanket wash solvents are typically between 80% and 100%.

Using the conservative figure (80%), a density of 0.87 kg/liter (typical for xylene), and applying a basic VOC emission equation, we can estimate the quantity of gas that would otherwise be released to the atmosphere, thus:

ME = Q x D x c
ME = Total uncontrolled VOC emission, kg
Q = Total consumption of material, liters
D = Density of material, kg/liter
c = VOC content by weight in the material, %
ME = (30,000 liters/week x 50 weeks) x 0.87 kg/liter x 80%
= 1,500,000 x 0.87 x 80%
= 1,044,000 kg/year
= 1,044 tonnes/year
At a VOC level of 100%, C.L.E.A.N.’s process would prevent the release of 1,305 tonnes of VOC per year.

Improved Productivity And Competitiveness For The End User

Lithographic printers are able to participate in C.L.E.A.N.’s Closed Loop Solvent Recycling System both as contributors and as consumers. Printers may choose to direct their waste stream into C.L.E.A.N.’s loop for reformulation without any obligation to purchase blended solvents. They may also purchase blended solvents while continuing to use traditional disposal methods.

This arrangement gives the end user maximum flexibility in their choice of suppliers, while enabling them to leverage the environmental benefits of this technology. In their marketing efforts, printers are thus able to project a “green” image to an increasingly environmentally conscious public.

An Expanding Canadian Market

The Canadian printing industry touches everyone’s lives through the newspapers, books, magazines, and even admail we all come in contact with every day. With over 98,000 employees, it is the fourth largest manufacturing employer in the country, with an annual output of over $10 billion.

Through its Alliance Partners, C.L.E.A.N.’s Closed Loop Solvent Recycling System presently services Ontario and Quebec customers which represent, respectively, 50.1% and 27.2% of the Canadian market.

Referring to section 4.1 above, this translates into an additional 300 tons of VOCs per year that will be recovered as C.L.E.A.N. expands its operations nationwide, at current market penetration levels.

Expansion into the United States, the world’s largest contributor of greenhouse gases, is also underway.
