with destination to cement factories, a very low amount of it reaches this destination.
An alternative way to transform this problem into an opportunity consists into the transformation of bioliquid after its thermochemical transformati... Autori: Ivana Moscato ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28289
SEPARATE COLLECTION OF MUNICIPAL SOLID WASTE AND FATE OF THE RESIDUAL UNSORTED FRACTION: A SCENARIO ANALYSIS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Three scenarios for the management of Municipal Solid Waste (MSW) produced in the study area of Bari (Southern Italy) were defined and evaluated in terms of separately collected material and fate of the residual fraction. The first scenario represented the
bring points MSW separate collection system in the current configuration with a collection rate approx. 40%. The second scenario considered the study area in the optimal configuration, with a percentage of separate collection > 80% obtaine...

FULL-SCALE APPLICATION OF MABR TECHNOLOGY FOR UPGRADING AND RETROFITTING AN EXISTING WWTP: PERFORMANCES AND PROCESS MODELLING
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 MABR (Membrane Aerated Biofilm Reactor) consists in an attached-growth process in which a gas permeable membrane is used as a biofilm carrier, and bubble-less oxygen transfer allows for a counter-diffusional mechanism where the electron donor (NH4+,
biodegradable organics) and electron acceptor (O2) reach the biofilm from opposing sides. The paper reports results form the largest MABR installation in the world, demonstrating the beneficial impact of the technology in terms of improved process r...

HOW TO DEAL WITH ORGANIC MUNICIPAL SOLID WASTE OVER-SIEVE FRACTION
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 The steady increase in separate waste collection has highlighted the urgent need to adequately deal not only with urban waste (differentiated and undifferentiated) but also with special waste produced by separate waste collection and recycling processes.
Source collected municipal solid waste produces different waste streams. One of this is the organic fraction of municipal solid waste (OFMSW). This fraction is central for circular economy, since it can be further transformed in order to recove... Autori: Ivana Moscato ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28302
SUSTAINABLE BIOMETHANE: METHANE SLIP REMOVAL APPLYING REGENERATIVE CATALYTIC OXIDATION (RCO) POST COMBUSTION TECHNOLOGY
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Biomethane is incentivized in Italy and in many other European countries as a substitute fuel for transport, in order to reduce fossil fuel and cut CO2 emissions. In Italy, Certificato di Immissione in Consumo (CIC) is actually sustaining biomethane production, charging petrochemical companies who need to cover their obligation quotes. Actually, biomethane production has to fulfil sustainability requirements in order to be entitled to get CIC. Sustainability principles are, among others, the typ...

CITRUS AS A MULTIFUNCTIONAL CROP TO PROMOTE NEW BIO-PRODUCTS AND VALORIZE THE SUPPLY CHAIN
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Citrus is one of the most important fruit tree crops worldwide, with respect to both total production and economic value. About 80% of the world production is destined to the fresh market, the remaining is processed to obtain various products (juices, jams, etc.). Citrus processing residues account for about 50-60% of processed fruits; their huge amounts and peculiar characteristics need a correct management that imply cost for producers and processors. If not well managed, they can represent an... Autori: Paola Sangiorgio ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28309
EVALUATION OF REMEDIATION TECHNOLOGIES FOR CONTAMINATED MARINE SEDIMENTS THROUGH MULTI CRITERIA DECISION ANALYSIS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Remediation of contaminated marine sediments present a difficult challenge for environmental decision-makers. In socially relevant situations, as in the Mar Piccolo of Taranto case study (Southern Italy), the decision-maker needs to explain to the citizens
why some remediation technologies are adopted compared to others. Multi criteria decision analysis (MCDA) is a scientifically sound decision tool for management of contaminated sites, not only to denote effective or technologically and econom...

DETERMINATION OF WATER QUALITY PARAMETERS IN IZMIT BAY (MARMARA SEA) AND CONCENTRATIONS OF HEAVY METALS BY ICP-OES
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 In this paper, seawater heavy metal concentrations (Al, As, Cu, Ba, Zn, Fe, Cd, Co, Cr, Pb, Mn, Mo and Ni) measured by ICP-OES and water quality parameters (NH4-N, NO3-, N, NO3, PO4-P, PO4-3, suspended solids, temperature, conductivity, pH and dissolved
oxygen) were evaluated in Izmit Bay (The Marmara Sea). The study was carried out seasonally between December 2016 and September 2017 at four separate sampling stations. The mean concentrations of heavy metals in mg L-1 were: Al: 0.074, As: 0.020... Autori: Arzu Morkoyunlu Yuce ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28333
STUDY ON ELECTROCHEMICAL ADVANCED OXIDATION PROCESS TO TREAT FISH MEAL INDUSTRY WASTEWATER
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Fish meal processing industries convert the raw fish into a various commercially edible form. The effluent generated from this industry comprises a large amount of pollutants leading to high values of biochemical oxygen demand (BOD), chemical oxygen
demand (COD) and total suspended solids (TSS). Mostly traditional biological and chemical methods have been adopted to treat the effluent coming out of the fish meal industry. By using these traditional methods at the end of the process, a large amo... Autori: Rajagopalan Varadarajan ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28335 |
