The built environment is responsible for a significant portion of global waste generation.
Construction and demolition (C&D) waste requires significant landfill areas and costs
billions of dollars. New business models that reduce this waste may prove to be financially
beneficial and generally more sustainable. One such model is referred to as the “Circular
Economy” (CE), which promotes the efficient use of materials to minimize waste
generation and raw material consumption. CE is achieved by maximizing the life of
materials and components and by reclaiming the typically wasted value at the end of their
life. This thesis identifies the potential opportunities for using CE in the built environment.
It first calculates the magnitude of C&D waste and its main streams, highlights the top
C&D materials based on weight and value using data from various regions, identifies the
top C&D materials’ current recycling and reuse rates, and finally estimates a potential
financial benefit of $3.7 billion from redirecting C&D waste using the CE concept in the
United States.
as front end planning (FEP), have a large impact on project success and significant
influence on the configuration of the final project. As a key component of FEP, front end
engineering design (FEED) plays an essential role in the overall success of large industrial
projects. The primary objective of this dissertation focuses on FEED maturity and accuracy
and its impact on project performance. The author was a member of the Construction
Industry Institute (CII) Research Team (RT) 331, which was tasked to develop the FEED
Maturity and Accuracy Total Rating System (FEED MATRS), pronounced “feed matters.”
This dissertation provides the motivation, methodology, data analysis, research findings
(which include significant correlations between the maturity and accuracy of FEED and
project performance), applicability and contributions to academia and industry. A scientific
research methodology was employed in this dissertation that included a literature review,
focus groups, an industry survey, data collection workshops, in-progress projects testing,
and statistical analysis of project performance. The results presented in this dissertation are
based on input from 128 experts in 57 organizations and a data sample of 33 completed
and 11 on-going large industrial projects representing over $13.9 billion of total installed
cost. The contributions of this work include: (1) developing a tested FEED definition for
the large industrial projects sector, (2) determining the industry’s state of practice for
measuring FEED deliverables, (3) developing an objective and scalable two-dimensional
method to measure FEED maturity and accuracy, and (4) quantifying that projects with
high FEED maturity and accuracy outperformed projects with low FEED maturity and
accuracy by 24 percent in terms of cost growth, in relation to the approved budget.
When I established Contento Recycling LLC in 2017, it was poised to be Central New York’s first ever construction and demolition debris recycling business. I was tasked with the challenge that many sustainability professionals are tasked with and that was to show the community why they should stop taking their construction debris to the landfill, and instead bring it to my recycling center for processing, recycling, and landfill diversion. Over the last several years I applied for state grant funding, spread awareness about my new business, designed and constructed a material recovery facility, outfitted equipment, and trained staff. I now have a facility that accepts about 40 tons of mixed C&D debris per day, and diverts about 20% of that from the landfill.
On a more personal level, I learned a tremendous amount about dealing with change management. I’ve learned a lot about business development, and some keys to success when building a business. I’ve figured out how to help my employees and customers grow. I’ve learned to be more patient and flexible with my business endeavors. I have a much clearer vision of what I want for my business and for myself. I have developed a rousing optimism on the impact that my business, and myself can have on the sustainable development of Central New York. I will be a leader in environmental stewardship and partner with other people and organizations who want to work towards a more sustainable future.
