Engineering education researchers and engineering accreditation boards have long stressed the importance of preparing engineers for 21st-century challenges by integrating professional knowledge, skills, and real-world experiences throughout the curriculum. This holistic approach enables students to connect various disciplinary content, hone professional skills through practice, and apply their developing engineering competencies to relevant problems and communities. While engineering curricula often incorporate integrated content in final-year capstone courses, earlier integration is frequently lacking. In 2020, _ embarked on a five-year NSF-funded Revolutionizing Engineering Departments (RED) project aimed at transforming its environmental engineering program. This initiative supported the development of new integrated and project-based courses to be implemented in the first and second year of the curriculum. All tenure-track faculty in the environmental engineering program participated in a collaborative, iterative process to design project-based courses for first- and second-year students. EENV 102, Introduction to Environmental Engineering Design and Sustainability, introduces the field of environmental engineering, sustainability concepts, and engineering tools like Excel and GIS in a project-based learning format. EENV 202, Sustainable Waste Management, combines systems thinking concepts, an introduction to ethics and social justice topics, and technical content related to solid and hazardous waste management with a life-cycle assessment project on laboratory waste streams. The initial offering of these courses took place in the 2023-2024 academic year. This paper reviews the design and implementation of these two new project-based courses and shares lessons learned. The findings can guide other programs in collaboratively designing integrated project-based engineering courses for first- and second-year students.
