DECONSTRUCTION OF THE BENEFITS
The process of deconstruction and salvage has economic and sustainability benefits, at the local, state, and federal levels. Let's break this down by looking into a hypothetical example.
Event: Portland, Maine adopts San Antonio's Deconstruction Mandate and requires that every house built before 1945 must be deconstructed. In conjunction with this mandate, the city has purchased an unused warehouse to store all salvaged materials for private/public deconstruction services.
Local Effect: This new ordinance now encourages new business development within the construction sector. This new development provides local, specialized jobs that not only provide a livable wage for their workers but also entice young Mainers interested in the construction trades to stay in Maine. Secondary effects of this change include:
Easier access to historic materials: This eases the burden often seen in historical restoration and creates a new marketplace, driving economic growth.
Reduced project cost: Case studies have shown that deconstruction net cost is significantly less than mechanical demolition in many residential and commercial projects due to avoided disposal costs and tax benefits of donating materials to reuse nonprofits. (EPA, 2025) and (Zahir & Syal, 2015)
Increased property value: This new process encourages more development or redevelopment in the region using quality materials. Market observations suggest that using recycled materials actually raises the project’s value. These new developments raise property values of surrounding areas, providing more property taxes for the municipality.
Reduced environmental impact: No matter how energy efficient a new building is, the impact of demolition and disposal of all the components of an existing building, plus the manufacture, shipping and installation of new materials, outweighs any potential energy savings. Deconstruction and salvage reduces the amount of materials that are disposed and not reused.
State Effect: Due to the increase in quality, high paying trades jobs, the state now has an increase in income tax. In addition to this, the resale of these recycled materials provides additional sales tax. These increases add to the state's revenue. Secondary effects of this change include:
Less Stress on state-owned landfills: Currently, construction & demolition waste account for more than 50% of all waste located in state owned landfills. This mandate would significantly decrease the amount of raw construction and demolition material being thrown into these landfills. The use of new materials also creates a large amount of waste from packaging materials and shipping; reusing local, existing materials would result in less waste and pollution.
Reduced state CO2 emissions: This reduction of construction and demolition waste from landfills significantly reduces the amount of CO2 produced during decomposition. This practice aligns with the state's Maine Won't Wait 2050 climate action plan by reducing greenhouse emissions and waste while creating new jobs.
Reduced in-state lumber & resource consumption: With an overall increase in stock of valuable structural materials, such as hardwood or stone, salvaged from older and existing buildings, there is a decrease in demand for in-state consumption of resources, helping preserve the natural environment. Also, many older buildings have old-growth wood which is stronger than today’s wood, and particularly viable for reuse projects.
Federal Effect: Similar to the state's benefits, due to the increase in higher paying jobs there is an increase in income tax. In addition to this, the country's overall consumption of virgin materials will have decreased, working towards the US's goal of Climate Neutrality by 2050. While this effect would be marginal, the overall contributions are not negligible, especially in the establishment of regional reuse infrastructures that make local policies more successful.
Considering the value of deconstruction and salvage from a humanist lens, it can be seen that its benefits go beyond economical value, but also preserve the humanity in many of these salvaged. In some former moment, a craftsman dedicated their skills to hand carving wood or stone into mantels and trim, applying generations of knowledge and melding tradition with styles and preferences of their time. Each piece contains stories and connects us to those who used these spaces and touched these materials before us.
Additionally, preserving historic fixtures and materials gives the community an opportunity to continue maintaining its historic culture by repurposing these materials for new projects. One such example is the MacDonald-Cartier Airport located in Ottawa, Canada, where a new extension was created using recycled wood from a historic World War II aircraft hanger previously on site.
CONCLUSION
Deconstruction and salvage recycles building materials and fixtures for future projects. This method was standard practice in the US up until the mid-20th century. With the need for fast and cheap housing, rapid urban renewal, as well as advancements in demolition technology, the practice of deconstruction quickly faded. With its popularity slowly coming back into the mainstream in the early 2000s, due to both its economic & sustainability benefits. Many large municipalities such as Portland, Oregon & San Antonio, Texas have enacted mandates for structures that meet specific age requirements, to be deconstructed instead of demolished. Practical benefits seen from this renewed practice include boosting job opportunities in the construction sector, stimulating local and state economies, increased accessibility to historic and quality materials, decreased net construction costs, and most importantly, decreasing CO2 emissions in the production and end of life stages of building material manufacturing. Like the practice itself, deconstruction and salvage has the opportunity to get a second life in the American construction industry.
