Nutritive values of green and black tea by-products and anti-nutritive activity of their tannins were evaluated in an in vitro rumen fermentation using various molecular weights of polyethylene glycols (PEG), polyvinyl pyrrolidone (PVP) and polyvinyl polypyrrolidone as tannin-binding agents. Significant improvement in gas production by addition of PEG4000, 6000 and 20000 and PVP was observed on...

The use of herbal products has increased significantly in recent years. Because these products are not subject to regulation by the Food and Drug Administration and are often used without supervision by a healthcare provider, the indication for and consumption of these supplements is quite variable. Moreover, their use is generally regarded as safe and natural by the lay-public. Unfortunately, ...

Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. The activity of this green catalyst was probed by the synthesis of aryl diazonium salts as the starting reactant and then, their diazo coupling with  2-naphthol to form azo dyes in a solvent-free medium at room temperature...

Na2SO4 as an inexpensive and effective catalyst has provided a green protocol for the synthesis of tetrahydrobenzo[b]pyran, pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2c]chromene derivatives from the three-component domino reaction of aromatic aldehydes and malononitrile with 4-hydroxycoumarin/ dimedone/ barbituric acid in ethanol/water as a mixture of solvent that, this mixture entirely is ...

Green chemistry is a tool, which when implemented right, can help the industry achieve its environmental goals. Broadly defined as the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances, green chemis t ry a l lows companies to develop better products through sustainable processes. In this article, we will summarize the dr ivers towa...

Along with a variety of actions to protect the environment, environmentally preferable purchasing (EPP), often referred to as “green purchasing” has been an emerging trend over recent decades all over the world. This trend is considered as a strategic alternative for all stakeholders in the society to promote the sustainable development of global production chain with the active involvement of ...

This article explores the impact of green manufacturing practices, disentangled in activities, investments, and type product made, on economic performance firms. Using survey data collected by European Commission from small- medium-sized enterprises (SMEs), we adopt self-determination theory to investigate extent which number made affects a firm's performance. We argue that consumers are affect...
