This paper presents for the first time the technological potential of novel Lantana camara-reinforced ethylene vinyl acetate (EVA) composites fabricated via the melt-blending technique. The composite and L. camara were characterized using X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and deferential scanning calorimeter. L. camara was found to drastically reduce the crystallinity of EVA from 44.3 % to a minimum of 1.16 %. Immersion of the composite specimens in de-ionised water showed that moisture absorption was less significant for composites with L. camara contents less than 15 % (w/w). A maximum sorption capacity of 1.20 mol% was recorded in 42 h which is remarkable considering the hydrophobic nature of EVA with 9 % vinyl acetate. L. camara and the composite removed 96 % and 88 % para-nitrophenol from water, respectively.
