In recent years, there has been a growing concern over the negative impact of plastics on the environment. Traditional plastics can take hundreds of years to decompose, and they are a major contributor to pollution, litter, and waste. One solution that has gained popularity is the use of biodegradable plastics. Biodegradable plastics are made from natural materials that can break down quickly and safely in the environment. These materials include corn starch, sugarcane, and other plant-based sources. Unlike traditional plastics, which are made from petroleum, biodegradable plastics do not contain harmful chemicals that can leach into the soil or water. One of the main benefits of biodegradable plastics is that they reduce the amount of waste in the environment. Since they can break down quickly, they do not accumulate in landfills or pollute waterways. This is especially important for marine ecosystems, where plastic waste can harm marine life and disrupt the food chain. Another ben...

  Introduction         —   Biggest sector in world in dollar values —   Oil and Gas   Sector has three Sectors       ◦        UpStream ◦        MidStream ◦        Down Stream What is Upstream —   Upstream is E&P (exploration and Production). This involves the search for underwater and underground natural gas fields or crude oil fields and the drilling of exploration wells and drilling into established wells to recover oil and gas. What is Mid Stream —   Midstream entails the transportation, storage, and processing of oil and gas. Once resources are recovered, it has to be transported to a refinery, which is often in a completely different geographic region compared to the oil and gas reserves.  Transportation can include anything from tanker ships to pipelines and trucking fleet...
