The hierarchy of waste refers to the “3 Rs” i.e. Reduce, Reuse and Recycle, which implements the strategies of waste management according to their specifications in terms of waste minimisation. The power of solar was exposed to people when Jawaharlal Nehru National Solar Mission (JNNSM) was introduced in the country in the year 2010.From then on people started to install and set up the solar as they came to know that the end life of it is around to be 2035. But none of them thought about future, i.e. what would happen to the solar panels when they are not able to generate power. Now the main issue is how will India be able to discard nearly 90 GW worth solar panel in the next 20 years? Where an average solar panel sized 250 watts, 90GW will amount to almost 7.7 million tonnes of E- waste at the end of a lifetime of a solar plant [1]. This paper mainly focuses on how these E-wastes produced can be reused and recycled.

Technology Lifecycle Management (TLM) is an organization that was developed to bring Equipment Maintenance and Equipment Sustaining Engineering into a single umbrella to deliver Technology Assurance to Operations. This means to better manage and continuously improve the equipment in the field. In the Middle East Center for Reliability and Efficiency (MECRE) we aim every day to ensure that the equipment is maintained at the right level, defects are properly reported, repaired, investigated, work orders are rightly completed, and the team works efficiently and safely. In Well Services this vision was enabled by developing a customized mobile business system to maintain complex processes and tasks. This digital system is referred to as MTEcosystem (MT-Maintenance Tool). It can harness bigdata and process them smartly and efficiently. MTEcosystem captures all the information related to asset maintenance, reporting and real time equipment data. With this digital enablement, there is a need to rethink the equipment performance and monitoring to move from the traditional reactive or preventive maintenance to an evolving predictive maintenance.

Greenhouse gas (GHG) emission is a worldwide concern and emissions with fossil fuel are increasingly questioned. As Schlumberger, we have committed ourselves in Paris agreement for setting science-based targets to reduce our greenhouse gas (GHG) emissions on all the 3 scopes of carbon emissions. This is also a part of Schlumberger's vision towards Net Zero emissions which will help in the transition to a sustainable future. Our CEO Olivier Le Peuch said, "Schlumberger seeks to lead positive, measurable changes in GHG emissions within the industry to help reduce climate change". Energy industry has a key role to play in reducing the effects of climate change. Schlumberger takes pride in technology leadership paired with social and environmental responsibility. Today along with Schlumberger, world's iconic companies like Microsoft, Shell and BP have also committed for Carbon reduction, Carbon negative and Net Zero. Schlumberger is proud to say that it is the first Company in Upstream Exploration & Production Services to set an Ambition to achieve Net zero by the year 2050. In June 2021, we announced that this reduction will be achieved by reducing 30% on Scope 1 and 2 by 2025, 50% on Scope 1 and 2; 30% in Scope 3 by 2030 and Net Zero by 2050. The reduction of carbon emissions starts with the quantification of carbon emissions and this project is in line with the company's commitment to Net Zero. The project focuses on Scope 3 Emissions which has never been done in a systematic way in the past. Middle East Center of Reliability and Efficiency (MCRE) in Dammam is one of the pioneers to kick start this quantification of GHG emissions to show that we can make a significant impact towards setting this target. For this to happen, we quantified emissions for specific Technologies related to Scope 3 to benchmark our baselines so that we can put a plan to reduce them. This project established Carbon footprint as an Assessment tool to Simulate Emissions. The tool will provide a competitive advantage in terms of Sustainable Development for Schlumberger and other Oil & Gas industries worldwide.
