Abstract One of the causes of climate change is the accumulation of greenhouse gases (GHGs). Methane (CH4) is one of the greenhouse gases, with an ability to trap heat in Earth's atmosphere 21 times greater than carbon dioxide (CO2) per unit mass and in the same period of time. Because the lifetime of methane in the atmosphere is relatively short, it could be kept under control. Wastewater treatment plants (WWTPs) are anthropogenic sources of CH4 emissions. Anaerobic digestion of t...

In this study major factors affecting the phenolation process of lignosulfonate (LS) waste liquor (recovered from pulp and paper industry) were optimized in order to improve LS substitution for replacing petroleum-based phenols during phenolic resin manufacturing. Four different parameters, namely phenol/lignosulfonate ratio, time, temperature and lignosulfonate waste liquor concentration, were varied in an experimental program having as response function the reaction yield. Response Surface Met...

Urban expansion, often seen as an indicator of economic growth and a possible response to housing crisis in big cities, is the main driver for carbon emissions in the metropolitan area due to higher values of household income, vehicle ownership and home size. The transport related pollution includes over 200 different compounds: besides CO2 emissions, CO, NOx, BTX and dust resulting from exhausting processes, from abrasive wear of brakes, tires and road surfaces. The expansion of the urban areas...

The emissions of greenhouse gases (GHG) from anthropogenic activities have still been a topical and much-discussed issue. In farming, room for reducing GHG emissions may also be available in crop farming. The measures aimed at the mitigation of GHG emissions may include a change in the farming system or partial switch to more extensive farming methods, including organic farming. The life cycle of oat, rye, wheat and spelt wheat cultivation in conventional and organic farming systems in the condi...

Livestock production is under growing public and scientific scrutiny for its greenhouse gas (GHG) emissions. This article contains a preliminary assessment of the inclusion of upstream life-cycle GHG emissions in concentrated feeds design, using the most common nonlinear programming optimization algorithms to determine feed composition. First, GHG emissions are included as costs in a single criteria optimization problem. The unit price of GHG emissions was obtained using a genetic algorithm. Sec...

A factorial design analysis was performed in order to determine the significant factors influencing cadmium removal from aqueous solutions by powdered marble wastes (PMW), using a continuous stirring tank reactor (CSTR) system. Investigated factors were initial cadmium aqueous concentration (5-30 mg L-1), PMW dosage (5-15 g L-1) and flow rate (20-40 mL min-1). Results showed that the cadmium aqueous concentration and PMW dosage were the most influencing factors on metal removal from synthetic aq...

On freeways with multiple on-ramps, it is a common practice to design a ramp metering strategy so as to regulate the entering rates from ramps and minimize the disruptions on the mainline. Most of the existing studies examine the performance of ramp metering on mobility and safety, rather than their impacts on the environment. This paper focuses on the estimates of vehicle emissions along mainline freeways under various ramp metering strategies. Vehicle speed and acceleration rates were measured...

The effects of gas addition on efficiency and CO2 emission were investigated with a compression ignition (CI) engine and a spark ignition (SI) engine operating with hydrocarbons-based fuels. Hydrogen rich gas (HRG) provided by an electrolyze, was aspirated into the air stream inducted in the engine cylinders. Investigation was conducted at engine light and medium loads and speeds, with relative low concentrations of HRG. For the CI engine, HRG addition up to 12.5% energetic fraction in fuel lowe...

Neural networks are a series of simple mathematical models, created on the architecture of human brain which gives a superior capacity of learning based on numerous connections established among neurons. The artificial neural networks have strong units of processing which are characterized by an extreme simplicity, but because of their whole interaction, the results are complex. The paper presents the comparison of two methods: mathematical regression and artificial neural network, used for pred...
