OBJECTIVES:

The BIOFOAM project aims to develop new types of aliphatic block co-polyesters that will tackle the biopolymer issues in an innovative fashion. Byway of selecting an inexpensive bio-source feedstock, new block-co-polyesters will be synthesised for use in rigid and flexible foam applications. All possible routes for developing an inexpensive bio-source feedstock will be explored. Via LCMA, various biopolymers versus petroleum based polymers are compared for use in foams to determine the most viable options. Based on patented technology of the University Twente block co-polyesters of the type Polyester-co-amide and Polyester-co-urethane biopolymers are first prepared on a laboratory scale. Subsequently, selected biopolymer compositions that meet the criteria of low cost, recyclability, environmentally friendliness and performance properties for targeted foam applications are manufactured on a pilot plant scale. An intensive property characterisation combined with numerical modelling of the foaming process guides the final biopolymer selection. Existing foam processing equipment is optimised for maximising the structural performance of the biopolymer. Eventually, specific foam applications are tested and presented as alternatives to selected Polyurethane, Polystyrene and Emulsion polymer foam applications. The biofoams recyclability is studied in term of material recovery, bio-source recovery, energy recovery, and biodegradability. An innovative Life Cycle Management Analysis is used to support all critical decisions in the various workpackages.

The BIOFOAM project objectives are:

1. Define and use a renewable bio-source based feedstock for the synthesis of recyclable aliphatic block-co-polyesters with an emphasis on Poly(ester-co-amide)s and Poly (ester-co-urethane)s.

2. Chemically synthesise with high efficiency a range of block co-polyesters that meet the processing and intrinsic property requirements of a foam application at a cost of less than 1 Euro per kg.

3. Develop industrially important biopolymer foams that contribute to the efficient and cost effective recyclability of waste streams. At least one novel biopolymer for a high value, foam market application currently dominated by Polyurethane, Polystyrene and Emulsion polymers.

4. Develop a numerical model that allows quantitative 3-D predictions of a foaming process for chemical and physical blowing agents and that takes into account the novel biopolymer rheology and processing conditions.

5. Develop and apply a Life Cycle Management Analysis (LCMA) method that integrates economic, environmental and societal considerations to direct the renewable bio-source, biopolymer and biofoam developments. Integrate the methodology into a software package to provide a European Work-process guideline for new product developments.

ABSTRACT:

THE BIOFOAM PROJECT AIMS TO DEVELOP NEW TYPES OF ALIPHATIC BLOCK CO-POLYESTERS (POLY(ESTER-AMIDE)S AND POLY(ESTER-URETHANE)S), AND INDUSTRIALLY IMPORTANT FOAMS MADE THEREOF. THE COMBINATION OF INEXPENSIVE RENEWABLE BIO-SOURCE BASED FEEDSTOCK, EFFICIENT CHEMICAL SYNTHESIS, AND HIGH VALUE FOAM APPLICATIONS LEADS TO AN INNOVATIVE APPROACH TO MAKE BIOPOLYMERS COMPETITIVE IN THE MARKET PLACE. THE NEW LOW COST BIOPOLYMERS (<1 EURO/KG) PROVIDE OPPORTUNITIES FOR TAILORED BIODEGRADABILITY AND PERFORMANCE PROPERTIES. A FOAM MANUFACTURING PROCESS IS OPTIMIZED FOR BIOPOLYMER PROCESSING BY USING NEWLY DEVELOPED 3-D FOAMING PROCESS SIMULATION SOFTWARE. AN INTEGRATED LIFE CYCLE MANAGEMENT ANALYSIS METHODOLOGY DIRECTS THE ENGINEERING DECISIONS AT EACH STAGE OF THE PRODUCT DEVELOPMENT CYCLE. ENVIRONMENTAL, ECONOMIC AND SOCIETAL ASPECTS ARE SIMULTANEOUSLY ASSESSED. THE PROJECT IS MANAGED FOLLOWING A DEVELOP AND COMMERCIAL TECHNOLOGY STAGING WORKPROCESS. A MULTI-DISCIPLINARY APPROACH OF WORLD LEADING EXPERTS IN COMPLEMENTARY INDUSTRIAL AND ACADEMIC FIELDS IS USED TO ACHIEVE THE BIOFOAM PROJECT OBJECTIVES.
