Paint recycling

The first large commercial application of UF was paint recycling, followed by dairy whey recovery in the mid-1970s. tJF applications are enabled by low-temperature and low-cost operation. 

Automotive applications require reduced cost and potential recyclability to meet end-of-life vehiele legislation requirements (see next section). Co-injection offers not just the potential to ineorporate recyclate in the core but also to utilise post industrial painted recyclates. One such example is the Ford P207 Fascia which uses recyclates in this manner to achieve part recyclability. Once the initial capital machine cost is overcome it is also an economical approach in terms of both material utilisation and recycling potential. 

Cobalt. There is no U.S. mine production of cobalt. Refining of imported nickel—cobalt mattes has not occurred since the mid-1980s. About 1600 t of secondary cobalt was recycled from scrap by 13 faciUties in the United States representing - 22% of total U.S. consumption. The price of the metal was around 44/kg. Most is imported from Zaire and Zambia. Increasing quantities are coming from Russia. Historically, the price of cobalt has been quite volatile and dependent on the pohtical environment in those countries. Cobalt is used in superaHoys, 40% catalysts, 14% paint driers, 11% magnetic alloys, 10% and cemented carbides and other uses, 16%. 

This article presents details of the gloomy picture of the environmental impacts associated with PVC waste which has been painted by four PVC waste management studies carried out for the European Commission. The studies cover mechanical recycling, feedstock recycling, behaviour in landfill, and the influence of PVC on incinerator flue gas cleaning residues. 

Water is one of the most widely used raw materials in the manufacture of aqueous paint formulations. But as well as being used in production it can have a number of other uses, e.g. cooling and cleaning. Because of the cost of "new" water and disposal of contaminated water most manufactures have introduced closed loop or recycling systems. 

U.S. EPA has proposed TSCA standards for the disposal of lead-based paint (LBP) debris to replace RCRA regulations. The new standards would establish disposal standards for LBP debris and identify recycling and incineration activities that would be controlled or prohibited. To avoid duplicative regulation, the waste that is subject to these new standards would not be subject to RCRA hazardous waste determination. 

Loop A continuous process for polymerizing aqueous emulsions of olefinic compounds such as vinyl acetate. Polymerization takes place in a tubular reactor (the loop) with recycle. Invented by Gulf Oil Canada in 1971 and further developed by several United Kingdom paint companies. It is now used for making copolymers of vinyl acetate with ethylene, used in solvent-free paints and adhesives.

In 1992, Volvo built an aluminum-bodied hybrid Environmental Concept Car (ECC) to California emission mandates. It had the recyclable plastic panels and water-based paints that are used by Volvo. A series hybrid drive train was used where a diesel gas turbine drives a generator to charge a battery pack to power an electric motor. The system is complex, but the car achieves good performance with low emissions and a 400-mile range. 

The recycling treatments and the possible presence of pollutants, paints or other surface products cause a reduction in the mechanical properties of recyclates, notably the impact strength and the ultimate characteristics. On the other hand, it is possible to upgrade the recyclate using additives or compatibilizing surface treatments. 

In contrast, PET end-use markets have been developing for at least 10 years. When the PET bottle was introduced in 1978 and was collected in states with deposit laws, the industry for recycling them and reusing them began to develop. PET resins can be reused to make polyols for insulation and unsaturated resins for bathtubs, shower stalls, boat hulls, and auto panels. Reclaimed PET is also used for strapping, paint brushes, geotextiles, fibers for fiberfill and carpets, and other textile applications.
