“…The reactor was loaded with 4-NP aqueous solutions (5.0 g L −1 ) and heated by immersion in an oil bath at controlled temperature. Upon stabilization at 80 • C, the solution pH was adjusted to 3 by means of H 2 SO 4 and NaOH solutions, and the experiments were allowed to proceed freely, without further pH conditioning. A calculated volume of H 2 O 2 (30% w/v) was injected into the system, in order to reach the stoichiometric amount of H 2 O 2 needed to completely mineralise 4-NP (17.8 g L −1 ).…”

a b s t r a c tMagnetite, nickel and cobalt ferrites were prepared and encapsulated within graphitic shells, resulting in three hybrid magnetic graphitic nanocomposites. Screening experiments with a 4-nitrophenol aqueous model system (5 g L −1 ) allowed to select the best performing catalyst, which was object of additional studies with the liquid effluent resulting from a mechanical biological treatment plant for municipal solid waste. Due to its high content in bicarbonates (14350 mg L −1 ) and chlorides (2833 mg L −1 ), controlling the initial pH was a crucial step to maximize the performance of the catalytic wet peroxide oxidation (CWPO) treatment. The catalyst load was 0.5 g L −1 , a very low dosage when compared to the high chemical oxygen demand (COD) of the effluent − 9206 mg L −1 . At the optimum operating pH (i.e., pH = 6), ca. 95% of the aromaticity was converted and ca. 55% of COD and total organic carbon (TOC) of the liquid effluent was removed. The biodegradability of the liquid effluent was enhanced during the treatment by CWPO, as reflected by the 2-fold increase of the five-day biochemical oxygen demand (BOD 5 ) to COD ratio (BOD 5 /COD), namely from 0.21 (indicating non-biodegradability) to 0.42 (suggesting biodegradability of the treated wastewater). In addition, the treated water revealed no toxicity against selected bacteria.Lastly, a magnetic separation system was designed for in-situ catalyst recovery after the CWPO reaction stage. The high catalyst stability was demonstrated through five reaction/separation sequential experiments in the same vessel with consecutive catalyst reuse.

“…Several studies on laboratory applications of the DBD for VOC removal focused on single VOCs (Magureanu et al, 2007;Gandhi et al, 2013;Quoc et al, 2011;Ragazzi et al, 2014), whilst real emissions from industrial or waste treatment plants include a large variety of compounds. However, the number of studies focusing on mixtures of VOCs is still limited.…”

“…The aerobic process produces CO2, H2O, nitrates, sulfates and heat in addition to a stable solid material commonly used as fertilizer for agriculture crops [42][43]. The adoption of direct composting (that is without a pre-stage of anaerobic digestion) does not change the amount of compost produced.…”

Abstract. In 2015 the European Commission issued a package of documents on Circular Economy concerning an integrated revision of legislative proposals on waste management. The aim was to stimulate a European transition towards a circular economy concept, which is expected to foster competitiveness, sustainable economic growth and new jobs generation. Three indicators are proposed in this paper to contribute to the assessment of the energy recovery management performance from MSW in a scenario of circular economy: a) referring to MSW directly used (RMSW) or indirectly used (SRF) as input of thermochemical plants, an indicator can be the percentage of waste having LHV > 13MJ/kg; b) referring to the MSW directly or indirectly used as input of thermochemical plants, the percentage of waste having ash recovered; c) referring to food waste, percentage of this stream sent to anaerobic digestion. The above indicators, proposed and discussed in this paper, have to be integrated with other ones in order to complete the quantification of the role of MSW management in term of energy recovery under a circular economy strategy. It is not the aim of the present paper to give a comprehensive solution to this complex issue.
