9th International Summit on Global Warming and Environmental Science August 10-11, 2020 Stockholm, Sweden

Biography:

John Shegerian is Co-Founder and Executive Chairman of ERI, the leading fully integrated IT and electronics asset disposition provider and cybersecurity-focused hardware destruction company in the world.  Under John’s stewardship, ERI is now capable of recycling more than a billion pounds of electronic waste has become the leading recycler of electronics in the World, regularly partnering with some of the largest electronics manufacturers on the planet.    

 

Abstract:

Effective recycling of e-waste – and all the elements extracted from it – is crucial for the environment in terms of reduced the leaching of toxins into landfills.  When done correctly, it can also reduce millions of pounds of CO2 emissions; reduce millions of pounds of water emissions; billions of killowatt hours of electricity; and millions of pounds of air emissions. New innovations have led to the recycling of e-waste playing a key role in th ecircular economy – leading to historically challenging elements such as plastics, glass and metals providing foundational ingredients for new useful products. But there is another element that must be extracted carefully and destroyed in this process and that is data.  As electronic devices become smaller, enormous amounts of sensitive and personal data are stored on eben the tiniest of devices. Due to this, the recycling of electronics faces a huge obstacle in the form of digital privacy. Many organizations – huge multinational corporations and global government agencies included – are reluctant to recycle their electronics for fear that their private or personal data will be compromised. And the fears are not without merit.  The recycling of e-waste has indeed become an issue that transcends environmental responsibility – still the principle motivation - and has moved into the realm of national security and data protection.

In this informative presentation, John Shegerian will discuss how the electronic recycling industry is at a crossroads of dual responsibility – reducing emissions/keeping toxins out of landfills WHILE also responsibly and efficiently achieving data destruction. It can be done and he’ll explain how.

Among the issues he will address are: Responsible recycling and its role in reducing emissions and the emergence of the circular economy.  The environmental issues to be considered globally;Why data needs to be managed in the recycling of e-waste

He also worked on bio degradation of plastics, bio removal of Fluoride in ground water, Climate change studies and on development of Silver Nano particles for addressing metal pollutants in aqueous solutions. Good number of students are benefitted by the research studies of Prof. P. V. V. Prasada Rao. Dr. Rao published more than 85 scientific papers in both National and International Journals. He is at present working as a Professor & Head of the Dept. of Environmental Sciences, Andhra University, Visakhapatnam, India.

 

Abstract:

India’s per capita water availability had declined 70% since 1951 and the rate of decline is expected to increase rapidly due to the population rise linked with the lifestyle changes and climate change consequences. India’s sustainable future lies in the efficient water management systems, more particularly with treatment and recycling of wastewaters. This paper presents a community friendly treatment practice for removal of Cd (II) and Sn (II) from wastewaters generated from electroplating and jewellers’ workshops, where water contamination by these two toxic metals are high.

 

               Through a screening study to find inexpensive adsorbents of heavy metals, Ground nutshell was found to be effective for different metals at varying efficiencies. In case of Cd (II) and Sn (II) the material found to be very efficient and the efficiency found to be varying with the particle size of the bio sorbent. Maximum adsorption was recorded with 0.21 mm particle size.  

              

               Investigations revealed that the rates of removal of Cd (II) and Sn (II) from aqueous solutions are dependent on contact time, pH, adsorbent dosage, and initial concentration of metal ion (adsorbate). Maximum adsorption of Cd (II) and Sn (II)   occurred at pH 6.0 and pH 2.0, respectively. Among the different sets of experimentation, maximum adsorption of Cd (II) and Sn (II)    was recorded at 0.210 mm of particle size, 50 mg/ml of adsorbent concentration at pH 6.0 and 2.0, respectively. Field studies indicated 57% of Cd (II) and 82.5% of Sn (II) are removed from electroplating industry wastewater. The results of the study reveal that Ground nut can be effectively used for Cd (II) & Sn (II) removal from the electroplating effluent waters, by optimizing the technique in the field trials.
