This study addressed the development of a pilot plant for pyrolysis scrap tires to obtain carbon black and other byproducts. The work was motivated by goal contributing dissemination knowledge about existing technologies that allow modern economies transform waste into valuable products, documenting discussing an empirical application in Brazil. Thispaper describes market steel scrap, pyrolytic oil products obtained from vacuum process. research conducted Brazil, guided twofold purpose...
In this research, products with high quality were obtained from natural sources. The sensorial qualities, chemical characterization, and physical properties of gelatin extracted chicken feet compared commercial gelatins. extraction process was performed using acetic acid on a concentration ranging 0.318% to 3.682%, processing time between 1.0 h 8.4 temperature 43.3 °C 76.8 °C. After the end each assay, yield measured. Results showed that, under best conditions, collagen above 8%, comprised...
The Brazilian energy grid is considered as one of the cleanest in world, because it composed more than 80% renewable sources. This work aimed to apply levelized costs (LCOH) and environmental cost accounting techniques demonstrate feasibility producing hydrogen (H2) by alkaline electrolysis powered grid. A project production, with a lifetime 20 years, had been evaluated economical sensitivity analysis. production capacity (8.89 46.67 kg H2/h), volume (25 100%), sale price (1 5 USD/kg H2) MAR...
This work shows a proposal for reducing emissions, fuel costs, and respiratory disease hospitalizations using environmental cost accounting principles the production of biodiesel from waste frying oil (WFO). PM10, PM2.5, O3 data 2017 to 2022 were collected correlated with number diseases their costs. WFO samples locally households restaurants in greater ABC region, Brazil, was produced samples. The results showed that throughout studied period, one or more polluting gases strong correlation...
Background: This study applied levelized cost of hydrogen (LCOH) and environmental accounting techniques to evaluate the feasibility producing green (GH2) via alkaline electrolysis for use in a bus fleet Fortaleza, Brazil. Methods: A GH2 plant with 3 MW wind tower was considered this financial project. sensitivity analysis conducted assess economic viability project, considering influence production volume, number kits, financing time, other kay indices. Revenue derived from sale...
This study focused on verifying whether the emission of air pollutants in São Paulo increases costs and number hospitalizations for respiratory diseases Brazil. Data pollutant emissions, hospitalizations, hospital were collected from 2008 to 2017 correlated with quality standards. The results showed that concentration particulate matter increased each year during period was highly due diseases. Ozone (O3) within standard throughout but registered an increase mean a positive correlation...
Renewable energies are cleaner forms of energy, and their use, has intensified in recent decades. Thus, this work presents a proposal for reducing the emissions, fuel cost, respiratory disease hospitalizations using environmental cost accounting principles to produce biodiesel production from waste frying oil. In our methodology, we conducted surveys, collected cooking oil samples local households restaurants São Paulo city, Brazil. Then, produced these samples. Data on air pollutants were...
The concentration of pineapple juice is needed to retain the bromelain activity and standardize composition proteolytic activity. Thus, this work aimed obtain a pure extract from Ananas comosus L. Merril by membrane separation process. A 2² experimental planning was used study influence pH transmembrane pressure on recovery micro-filtration using plain membrane. In second step, enzyme purified ultra-filtration 10 kDa millipore kit. best operation condition at 7.5 0.05 bar, while 85%...
In this work, the thermodynamic equilibrium and applying of PEG4000/Phosphate ATPS on purification bromelain extracted from pineapple was studied. A rigorous study curves tie-line length PEG4000/phosphate were done for pH 6-11 at 25ºC. Results showed that there augment in PEG salt contents with high value two-phase formation needed only increasing content. Two 11 optimal condition purification, one composition 14% 13% other 12.6% 12.2% salt, while a 25-62 folds enzyme found. SDS-PAGE...
This work aimed to study the partitioning of a lipase produced by Burkholderia cepacia in PEG/Phosphate aqueous two phase system (ATPS) and its characterization. Lipase was B. strains fermenter. Enzyme occurred at pH 6.0 8.0, using PEG 1500 6000 on tie lines. Metal ions, temperature effects enzyme activity were evaluated. Five milliliter 7.5% olive oil emulsion with 2.5% gumarabic 0.1M sodium phosphate buffer 8.0 37ºC used for determinations. Results showed that crude stratum from...
This paper presents a case study conducted at food supply centre in shopping São Paulo city, Brazil. A waste digester was developed based on specifications provided by GE for the generator, and cost of electricity production from generated region subsequently assessed. Results show that 1,368,750 m3 biogas produced year, which reduction 14% consumption is equivalent to USD 854 thousand per year. The amount carbon credits 10,775 metric tons CO2 51,840 organic humus energy had unit 0.10...
In this work the α and β-amylase enzymes were obtained from maize (Zea mays) malt biochemistry characterized. A germination study to obtain with good amylase activity was made. The seeds germinated in laboratory enzymatic measured daily. Activity dependence time fitted an exponential model (A=A0eµt), which showed that behaviour of process similar growth microorganism. Its could be applied describe mechanism α-amylase production for each varieties others cereals. Maize characterization had...
This work aimed to produce jellies with the collagen extracted from chicken feet. Jelly samples were prepared flavors of pineapple (GAB) and white chocolate (GCB). Using a hedonic scale, 30 untrained tasters evaluated sensory acceptance willingness consume jellies. Results showed that GCB GAB samples, respectively, scored 7.8 7.4 in scale for all attributes; indicating both products had good acceptance. In relation 85 74% consumers, declared they would once week.
This study compared reactive dyestuffs and vat in the dyeing of cotton. We investigated possibility reuse effluent generated, ecological costs, colorfastness to water, rubbing, daylight, perspiration. The experiments with showed slight advantage terms generating less molecules carbon dioxide than conducted dyestuffs, lower consumption energy, greater for treated effluent. In addition, exhibited decolorization efficiency above 99% rates total organic removal over 90% all cases, addition...
