Introduction. The purpose of this publication is to search for alternative materials -food industry wastes; valuation of it's use in the production of porous carbon materials (PCM) for use in water treatment systems.Materials and methods. Pyrolyzed wood waste (PWW) of the meat processing industry as raw material for the production of sorbents. Chemical activation of PWW by orthophosphoric acid. Using the adsorption-desorption methods of nitrogen, the porous structure was determined at 77 K; mesopore distribution by size and mesopore's volume -by BJH-method; distribution of micropores by size -using QSDFT-method; volume of micropores -by Dubinin-Radushkevich method; subnanopor's volume -by QSDFT-method.Results and discussion. The microporous structure has the following characteristics: pore diameters are in the range of D mi =0,60-2,5 nm, mostly represented by pores with a diameter of 0,87; 1,56 nm; volume of micropores -V mi =0,091 cm Conclusion. An energy-saving method is proposed for the production of PCM from secondary «renewable» resources -PWW, for use in water treatment systems. ─── Food Technology─── ───

“…It is indisputable that the activated carbon prepared via chemical activation offers higher yield at lower activation temperature with higher specific surface area than that through physical activation. Zinc chloride and potassium hydroxide are among the commonly used chemical activators for activated carbon (Marsh and Rodriguez-Reinoso, 2006;Heidari et al, 2014). In chemical activation, the carbonaceous material is first impregnated with the chemical activator prior to activation under anoxic environment or inert gas at temperatures between 400 and 600°C.…”

“…In chemical activation, the carbonaceous material is first impregnated with the chemical activator prior to activation under anoxic environment or inert gas at temperatures between 400 and 600°C. Upon which, the resultant activated carbon is soaked in dilute hydrochloric acid for demineralization, and thereafter is washed with distilled water to a constant pH (Heidari et al, 2014;Zaini et al, 2009).…”

The commonly used activators in chemical activation of activated carbon are very toxic and poisonous to the aquatic environment. Finding trade-off solutions without compromising the quality of activated carbon and jeopardizing the environment have become the subject of considerable interest. This paper is aimed to shed some light on the inevitable release of chemical activators to the aqueous environment, and offers some possible solutions to overcome the emergence of secondary pollution.
