Structural and functional evaluation of biochar produced from Spent Coffee Grounds (SCG) for AgNPs removal from industrial effluent

Title : Structural and functional evaluation of biochar produced from Spent Coffee Grounds (SCG) for AgNPs removal from industrial effluent

Abstract:

Silver is one of the precious metals and is most popular for its diverse applications in various industries. Major industries such as textiles, coatings, paint and pigments, cosmetics, medical and packaging utilized silver nanoparticles (AgNPs) during their manufacturing process. More than 1700 different products of these industries are available in the market which contains silver nanopatricles. According to the survey it has been found that total environmental emissions for AgNPs has raised upto 90% globally and around 83% at per industrial sector. These results show that AgNPs show the major environmental impact. Due to waste discharge from all these industries AgNPs get mixes with water bodies and contaminated on large scale. However, environmental exposure to these silver ions or silver nanoparticles through waste streams has become major threats for human health as well as for ecosystem. Biochar is a potential support matrix to immobilize nanoparticles on its surface due to presence of various functional groups on biochar surface with its porous structure which can be an advantageous factor for removing AgNPs from waste water stream. SCG is considered as one of the most common biomass waste with an estimated production of about 7×10⁹ kg/year. Biochar which is derived from SCG exhibits a significant amount of oxygen surface site with high surface area and some quantity of minerals. This work reviews the compositional and characteristics evaluation of SCGs derived biochar after pyrolyzed at several heat levels for better adsorption of AgNPs.

Audience Take Away

• This presentation will explain about cost effective methodology for waste water treatment so audience can have an idea about biochar application for environmental remediation
• Water pollution is main focused are at current time in which every industry and research laboratory  is working so proposed knowledge can be helpful at industrial level
• Most of the courses include environmental remediation in their curriculum so it is very much relevant for teachers and it is also a focused area in every country in which government is giving more concern so all researchers will get benefited by this knowledge
• Biochar is cost effective and more efficient so it can be utilized commercially after successful results
• This type of water remediation will help out ecosystem also to balance as mostly industry discharge their waste in water bodies due to which ecosystem get affected.
• Spent coffee ground biochar is producing in large quantity worldwide by this presentation researchers will come to know the utilization of SCG based biochar.
