Latex paint is recyclable, but oil-based paint are considered household hazardous waste (HHW). There are two types of recycled paint: re-blended (also called consolidated paint) and re-processed (also called re-manufactured paint). Re-blended paint contains a much higher percentage of recycled paint than re-processed paint.
Creating re-blended paint involves mixing several paints together, including various colors and sheens (glossy, eggshell, etc.). The paint is then filtered, packaged and distributed or sold.
Re-processed paint results from mixing old paint with new paint and other new materials. The paint is then tested for quality, packaged and distributed or sold . In the UK each year 50 Million Litres of unused paint is sent to landfill.
There has been some previous test in concrete mixes which have shown potential for using paint waste as an admixture, for improved workability, higher flexural strength, lower chloride ion penetrability, better resistance to de-icing salt surface scaling and can be more economic because they require less water-reducing and air-entraining admixtures.

Properties:
High polymer content, most white paints contain Titanium Dioxide (which can be used to purify air).
Based on Properties what can this do?
• Improved workability,
• Higher flexural strength,
• Lower chloride ion penetrability,
• Better resistance to de-icing salt surface
To what extent can it meet the projects aims?
To create an architectural façade system that will be made from a low carbon based concrete and use a waste stream that can act as a carbon sink to be used as a habitat for the growth of plants/ microbe / microorganisms.
• Permeability
• Large surface area for carbonation
• Growth on Façade
• All of this will need to be tested
