In my previous role, I was part of a team that developed a recycling initiative on campus. I led the research phase to identify the best materials to recycle. We collaborated with local waste management to implement it. As a result, we increased recycling rates by 30% in one year while raising awareness among students.

In a project aimed at reducing waste in our office, I encountered a conflict with the facilities team who were resistant to changing suppliers for recycling bins. I set up a meeting to understand their concerns and shared data on benefits of the new suppliers. We compromised by piloting the new bins in one department first, which led to a successful implementation across the office.

I led a project to reduce plastic waste by implementing a recycling program at our office. We established clear recycling bins and partnered with a local company to ensure proper distribution. This initiative reduced our plastic waste by 40% over six months, and it encouraged employees to adopt more environmentally friendly habits.

In my previous role, I faced the challenge of reducing waste at our manufacturing facility. The issue involved a high volume of plastic waste.
