Research Project: Production of Environmentally Friendly PHA Biopolymers from Waste BioGas Derived from Agriculturally-Derived Solid Waste Streams

Location: Bioproducts Research

2013 Annual Report

1a. Objectives (from AD-416):
To produce environmentally friendly Poly(Hydroxy-Alkanoate) (PHA) biopolymers from waste biogas, thus producing commercially-viable PHA blends that can be thermoformed into products. Commercial validation of the Mango Materials is to be demonstrated at scale using biogas from various sources, including ag-derived feedstocks, MSW, or wastewater-derived methane. Use of waste biogas from anaerobic digestion decreases the cost of raw feedstocks required to make Mango Materials’ bioplastics.

1b. Approach (from AD-416):
A bioreactor system will be set-up at ARS and maintained by Mango using methane and/or waste biogas to produce PHA. ARS and Mango will work jointly to assess the potential commercial viability of this process by testing fermentation conditions and by determining the quality and end-use mechanical properties of the biopolymers produced.

3. Progress Report:
Mango and Albany researchers have hit their target milestones for this joint effort, specifically, the process to produce bioplastics has been successfully scaled up from bench scale to pilot scale. The team now produces measurable quantities of biodegradable plastic which are being formed into test pieces for further evaluation. This project has been expanded in scope and resourses. The project directly relates to objectives 2 and 3, adding value to biomass and improved biorefinery strategies as defined in the parent project.
