Description:

Use Design for Disassembly (DfD) to address demolition-generated insulation waste; features pre-fabricated panels that are easily disassembled to optimize reuse with only minor reprocessing.

Objective:

Construction and demolition waste accounts for 52% of the total land-filled space (EPA, 2009). While many advances in disassembly sequencing in buildings have been proposed to recycle concrete, steel and tile associated with construction and demolition waste, the insulation contained within every building persists as a significant environmental challenge to recycle and reuse. The technical challenge addressed by this project is the curtailment of demolition waste associated with disposal of current insulation technologies.

Approach:

A Design for Disassembly (DfD) approach is taken address this challenge, and an alternative insulation system is proposed for further development and assessment. The proposed system utilizes the structure of prefabrication panels to employ an insulation system with complimenting manufacturing and disassembly processes to optimize the ability to reuse the proposed material in its totality with minor reprocessing required. Currently, even when deconstruction techniques are employed for homes, there are two primary issues associated with material recovery: lack of access to material, and the adhesive and varied nature of the material itself.

Expected Results:

The key contributions from this work include firstly, the development of insulation prototype aimed at reducing the amount of insulation waste land-filled and an exploration of associated functionality metrics (structural and thermal). Secondly, this project will produce a comprehensive inventory of life cycle data, and will quantify the emissions into the air, water, and land that take place through every life cycle phase associated with the traditional and redesigned insulation, as well as the potential for negative health effects associated with the production, use and end-of-life of each option. Lastly, this work will contribute an optimized manufacturing and disassembly processes for the alternative insulation, with a comprehensive cost-benefit analysis to determine value.
