November 2009: What do you think about Recycled paints?

Mainly recycled paints are old stock paint, which is already write off, so when we do recycled to those paints, it can reduce cost of raw material, so it mean that our profit will be higher than standard profit. In this case the recycled paint still can be rework with some adjustment.

Not everyone needs the performance of a virgin paint, so there should be quite a market for such products. Who typically needs to paint their warehouse, or even their office space, with brand new material? What color usually ends up on office walls anyway? The trick will be building infrastructure for recycling and repurposing, but there is work on that front as well.

The concept may work for consumer goods but I don't think it would be acceptable for OEM industrial coating where small levels of minior additives play a very large roll in coating performance

I had experience to recycle waterborne paint, alkyd based paint, NC base refinished paint. The main reason of these paint came from business decision with customers and dead stock in the factory.
Corrective action to recycle paint made from business decision is to rework them. Approximately 60% can be recovered. 40% has to be write off and find proper ways for disposal.
Corrective action to recycle paint from dead stock are divided in to two parts.
First part, Monthly SOP (Sale and Operation Meeting)must be effective to bring sale forecast accuracy to +/- 20% ( 80% or 120% accuracy level). This accuracy can be achieved if proper trainings are given to sale management team.
Second part is to design the production process in such a way that it can produce the paint just the quantity that the customers need not more and not less. Batch size may vary from 150 ltrs to 1,000 ltrs in one mixing vessel.
To do this you may use cone shape tank with VFD agitator. The agitator must be equipped with side wall scrapers. Mill base process must be imply to have the best result. To my previous experience,
150 ltrs or 10,000 ltrs of white paint can be produced within 30 minutes (before filling). This 30 minutes include QC time Suroj Sirirattanont

The main objective of the recycle lies with the objective 3R (reduces, reuse recycle). It saves the material. It saves the energy. In other words it reduces the waste burden to make our globe Green. No doubt, recycling contributes in material saving. Energy saving saves dollars and pounds but the contribution of recycle make our environment cleaner, safer and less polluted. In some cases the expense of waste handling are more than the recycling of the material. Risks are lower and economy is also there.
If don’t recycle the paint. What are other possible solutions?
Only burn it in the brick kiln and if it is hazardous waste: oh my God. It will give rise to VOCs, fumes, dust etc.
Being a chemist I will prefer to reuse or recycle it any cost rather than waste it by saleable waste.

It does add to value ,reduce watse & inventory.Stock old paint batches as per expiry date (shelf life),type
( industrial/decorative), & colours.Update records of such batches regularly & plan its work off in batches that are going to be processed. Before working off, it is safe to check its compatibilty in Laboratory before doing it in bulk..

Recycling paint is far less resource intensive than manufacturing
new paint. For example, re-using ten gallons of latex paint saves
1,060 kilowatt hours, enough energy to power the average
Oregon household for a month. There are two types of recycled
paint: consolidated and reprocessed. Trust Paint is consolidated
paint, which means leftover paint is simply reblended and filtered,
resulting in less water and no addition of toxic materials (such as
heavy metals and petrochemicals) when compared to producing
virgin paint.
Many latex paints contain organic solvents, which disperse and
bind other paint elements. These organic solvents emit volatile
organic compounds (VOCs), which are respiratory irritants and
contributors to the formation of smog. Since recycled paint
involves minimal processing, no new VOCs are produced during
its formulation. Additionally, lab tests show that overall Trust Paint
contains modest levels of VOCs.
Trust Paint uses 100 percent post-consumer paint collected
from the city’s hazardous waste program to produce its recycled
paint. This keeps paint waste out of landfills and provides a
locally-produced, high-quality recycled product to individuals,
governments, and businesses. Currently, Trust Paint represents
