Collaborating constructively for sustainable biotechnology

Area of Science:

• Biotechnology and synthetic biology for sustainable chemical and material production.
• Environmental science and life cycle assessment methodologies.
• Social science and constructive technology assessment frameworks.

Background:

• Societal needs demand novel technologies for sustainability.
• Biotechnology, particularly synthetic biology, presents bio-based alternatives to fossil-derived products.
• The sustainability of biotechnological solutions requires careful evaluation due to potential trade-offs.

Purpose of the Study:

• To assess the sustainability capacity of bio-based nylon production.
• To apply a Constructive Sustainability Assessment framework using deliberative and analytical methods.
• To demonstrate a collaborative approach for early-stage consequence anticipation and design modification.

Main Methods:

• Utilized a framework of Constructive Sustainability Assessment.
• Employed both deliberative and analytical approaches.
• Focused on the specific case of bio-based nylon production.

Main Results:

• Identified potential for life cycle carbon dioxide (CO2) and nitrous oxide (N2O) savings with bio-based processes.
• Reported mixed results across other environmental and social impact categories.
• Demonstrated collaborative knowledge generation for early-stage impact assessment.

Conclusions:

• Bio-based nylon shows promise for CO2 and N2O reduction but requires evaluation of other impacts.
• Collaborative and early-stage assessment is key to anticipating and mitigating sustainability consequences.
• The demonstrated approach enables technological developers to better understand and respond to product sustainability implications.
