How to manage plant biomass originated from phytotechnologies? Gathering perceptions from end-users

Area of Science:

• Environmental Science
• Biotechnology
• Renewable Energy

Background:

• Phytotechnologies utilize plants for environmental remediation and biomass production.
• Contaminated lands offer potential for biomass sourcing without competing with food production.
• End-user perceptions are crucial for adopting novel biomass sources.

Purpose of the Study:

• To assess end-user perceptions of using phytomanaged plant biomass in combustion and anaerobic digestion (AD).
• To identify potential benefits and limitations of utilizing biomass from phytotechnologies.
• To explore regulatory aspects influencing the use of phytomanaged biomass.

Main Methods:

• Questionnaire survey and interviews with stakeholders in the wood energy and AD sectors across four European countries.
• Inquiries focused on installation, input materials, phytostabilization, and phytoextraction processes.
• Analysis of perceptions regarding biomass suitability, risks, and economic drivers.

Main Results:

• Most respondents were unfamiliar with phytotechnologies, yet saw potential for biomass use in AD and combustion under specific conditions.
• Biomass from phytomanaged areas offers a non-food-competing source, particularly from contaminated lands.
• Cost and regulatory hurdles, including a gap in biomass status, were identified as key limitations.

Conclusions:

• Phytomanaged biomass is theoretically viable for energy production, with phytostabilization/phytoexclusion plants perceived as lower risk than phytoextraction.
• Economic incentives, like the price of biomass from metal-contaminated soils, could drive adoption.
• Addressing regulatory uncertainties and process costs is essential for integrating phytotechnology biomass into the energy sector.
