In this paper we evaluated impacts induced production polyvinyl chloride (PVC), one most widely used manufacture various goods. were calculated Life Cycle Assessment methodology. negative PVC may be reduced recycling, a sustainable, effective, currently available...

Bioplastics are biobased materials, usually easy biodegradable, derived from renewable resources.Evolution of bioplastics production is related to: bio starch and mixtures (74.5%); bioplastic products fermentation (13%), petrochemicals materials (12.5%).They seen as a viable solution to avoid some environmental impacts caused by the use fossil-based conventional plastics.In this context, general objectives study entail analysis selection optimal alternative able be used for packaging...

Environmental contamination with heavy metals, especially of soils and water, became a significant problem because most them are toxic to the living organisms, non-degradable persistent in contaminated media. Physico-chemical methods, such as chemical precipitation, electrochemical treatment, filtration, ion exchange, evaporation, reverse osmosis membrane technologies currently used methods remove metal ions from wastewaters. Bioremediation technologies, which known be environmentally sound...

For the protection of human and ecological receptors from effects soil pollution with chemical compounds, we need to know behavior transport pollutants in soil. This work investigated Congo red (CR) acid dye sorption on three natural soils collected central northeastern regions Romania, symbolized as IS-65, IS-T, MH-13. To define mechanism identify rate governing step, various diffusion models such Weber–Morris intraparticle diffusion, Boyd, film pores mass transfer analysis have been...

Until now, humanity has strived to makes efforts for warranting the economic development on a sustainable way well-being improvement, simultaneously with resource preservation and environmental protection.The industrial production processes, which generate added value ensure people welfare are in connection environment regarding consumption waste generation.In order work basis, industry should attain balance between economy, ecology community, long run.One may depend not as much of natural...

Due to the increasing and hazardous level of plastic pollution in our planet, many researchers experts from public private sector have been working order promote implement solutions overcoming this global issue.The present project joins scientific community discussion by focusing on polyvinyl chloride (PVC), which is considered one most used polymers engineering infrastructures.The goal paper quantitatively assess environmental impacts PVC production with aim proposing cleaner industrial...

Over time, the enormous amount of waste, generated worldwide, induces threats to environment. Most total globally, is represented by food which produced annually. The most relevant sources are and beverage industry as well households. purpose study to: (i) identify risk factors on human health production waste; (ii) analyze highlight best management alternatives for recovery recycling valuable components reduce environmental impacts risks diminish pressure natural resources.

This paper addresses the direct transfer of knowledge from university to manufacturing industrial sector, providing solutions transform production/manufacturing waste into resources and closing loops in process according circular economy values.For this purpose, eco-innovation eco-design were selected discussed order be applied as tools support context economy.These are focused on re-design products founded in-plant reuse production waste, followed by Life Cycle Assessment economic...

Two chelating resins (CRs) bearing iminodiacetate (IDA) groups derived from acrylonitrile -divinylbenzene (AN-DVB) copolymers having 10 and 15 wt.% nominal cross-linking degrees were used as sorbents for removal of heavy metal ions like: Cu 2+ , Ni Co aqueous solutions by batch technique.The experimental data analyzed pseudo-first order, pseudo-second intra-particle diffusion equations.The adsorption kinetics was well described the order equation, supporting chemisorption would be...

The reduction of production waste impact started to be an important subject in the context industrial development. In last years authorities became interested impacts generated by large amount waste, recycling or reuse processes. this context, present study is developed help decision makers take best regarding management from paper manufacturing so as mitigate its impacts. According results obtained after analysis conducted Life Cycle Analysis (LCA) framework, type can reduce considerable on...

As a result of the evolution industrial production electrical and electronic equipment increase population demand for these products, amount waste (WEEE, e-waste) has increased substantially in last decades. The paper makes brief analysis risks that poor WEEE management can generate environment human health offers some solutions sustainable model. One refers to use as secondary source critical metals, such cobalt, lithium etc., which be obtained from used batteries, by specific...

This paper delves into the process of phytomining, with a particular emphasis on recovery heavy metals, notably nickel. It explores role various participants in phytomining and factors that influence it. The underscores economic significance as technology for critical presenting several case studies these including noble rare earth elements, nickel, zinc, cadmium. also provides an in-depth analysis environmental impacts process, specifically through life cycle analysis. concludes by...

Today, it is estimated that about 88 million tonnes of food waste or 173 kilograms per capita are generated annually in the European Union. In farms, as well processing and production industry, shops, restaurants households, lost wasted along entire chain. Households first place generation waste. Lost contribute to climate change, with a global carbon footprint 8% total anthropogenic greenhouse gas emissions. Food fact loss resources, such land, energy, water others throughout life...

One of the largest water users in Europe and USA is bakery industry. Daily consumption industry varies from 10.000 to 300.000 buckets 10 L / day. Half this amount discharged as wastewater. Another aspect manufacture pastry products, which have their composition various raw materials that must be processed before forming a finished product. The results pollutants, waste, wastewater noise pollution. These pollutants cannot even called dangerous, toxic, or harmful, but they do participate some...

Environmental pollution with heavy metals has become a critical concern because of their potential to create negative ecological effects. Such toxic elements are considered pollutants the soil spread, appearance and acute chronic effect on cultivated plants. Excessive release into environment primary issue worldwide, as they cannot be transformed non-toxic forms therefore have long-lasting effects ecosystem. Many them even at very low concentrations. In this context, experimental program...
