Hazardous properties of paint residues from the furniture industry

Formulation effects on the release of silica dioxide nanoparticles from paint debris to water

“…In our study we artificially produced paint residues with reduced size (b4 mm), in order to match the EN 12457-3 requirements; then our paint debris exhibit a larger surface area per volume that can allow more rapid dissolution of paint constituents (Vaajasaari et al, 2004). According to the EN 12457-3 procedure, the eluent (water) is in constant contact with the granular material in order to establish a pseudoequilibrium, which is controlled by the solubility of the elements of the granular phase (Lopez Meza et al, 2008).…”

“…As commercial and industrial paints sold today may contain toxic chemicals such as biocides, it is very important that the removal, management and disposal of paint residues containing toxic chemicals is done properly to prevent any adverse effects on human health and the environment (US EPA, 2011). Vaajasaari et al (2004) demonstrated that harmful compounds remain in solid paint debris and may be leached into the environment when paint residues are in contact with water at landfill sites. Also, the direct environmental impacts of spent residues containing antifouling chemicals generated during the regular maintenance of boats have received increasing attention in recent years (Jessop and Turner, 2011;Singh and Turner, 2009;Holmes and Turner, 2009;Turner et al, 2009).…”

Chemical and ecotoxicological characterization of solid residues produced during the co-pyrolysis of plastics and pine biomass

“…Therefore, it is necessary to develop specific analytical procedures that are adequate for the determination of volatile organic compounds and non-volatile organic compounds in those materials and in their leachates. Several research works have described the release of organic compounds from different materials and residues: cement-based and stabilized materials [9], contaminated soils [10][11][12], paint residues of furniture factories [13], shredder residues [14,15], municipal solid waste incinerators fly ashes [15,16], varnish residue and urea resin waste [17], sewage sludge [18] and landfills [19][20][21][22][23][24][25][26][27].…”

“…The lighter members of this group are benzene, toluene, ethylbenzene and xylene (usually referred as the BTEX group), and they have a particularly high environmental mobility. Some authors [13,19,20,23,24,27] have studied the presence of aromatic compounds in eluates from different wastes and found that the compounds of the BTEX group are always present in relatively high concentrations, giving a major contribution to the Total Organic Carbon content of the eluates.…”

Treatment of door-manufacturing factories wastewaters using CDEO and other AOPsA comparison

“…Several papers have been published in the literature during the recent years about the treatment of the wastes produced in a wooden-door manufacturing factory [1][2][3][4][5]. Initially, the use of a coagulation-flocculation technology followed by a biological oxidation stage appears as a promising alternative from the economy viewpoint, but due to the presence of toxic and/or biorefractory species, biological techniques are not initially considered to be efficient enough for the treatment of these effluents [6][7][8], and although the combination of a coagulation-flocculation process with a sedimentation or a flotation process is able to reduce the colloidal adhesives contents [9,10], this treatment does not act against soluble pollutants, and consequently it leads to a low COD removal. So, it can only be used as a complementary treatment and not as a final one.…”
