Abstract:
The BIO-THERM project proposal refers to environmentally friendly products obtained from renewable raw materials, intended for insulating industrial buildings and equipment. The products submitted to be created by the project are biodegradable, with a high useful life and a low risk of bio-deterioration and fire. The project’s theme complies with Research theme 3.1.2, Environmentally friendly products (green chemistry), Research Direction 3.1, Means and mechanisms for reducing environmental pollution, Area 3, Environment.
The project’s overall goal is to obtain new biodegradable thermal insulating composite materials and their innovative use in order to increase the thermal efficiency of industrial buildings and equipment. The project’s specific goals are:
(i) The selection of fungus and bacteria groupings that efficiently form spongy structures from a mixture of lignocellulose, plastic and mineral materials;
(ii) The creation of inoculating bio-products for the fabrication of biodegradable thermal insulating composite materials;
(iii) Developing specific thermal insulating material forming procedures;
(iv) Determining the new materials’ characteristics;
(v) Setting the optimum usage methods for the thermal insulation of industrial buildings and equipment;
(vi) The intellectual protection of the innovative solutions;
(vii) The technical and economic and eco-efficiency analyses of the new biodegradable thermal insulating composite materials;
(viii) The wide-scale dissemination of the results obtained within the project
The project develops existing solutions for obtaining thermal insulating materials from spongy structures formed by fungi grown on lignocellulose waste, via contributions that reduce the disadvantages of the known solutions.
The goal of introducing thermal resistant recycled plastic materials (ex. polypropylene) is to reduce the bio-deterioration potential (by limiting the biocomposite’s bio-degradation speed) and to increase the mechanical strength by creating a framework of improved resistance.
Co-cultivating fungi with bacteria that stimulates their growth and forms biofilms on the plastic materials in the mixture aims to reduce the material fabrication time (and to increase the direct economic efficiency) and to achieve compatibility between the hydrophobic (recycled plastic materials) and hydrophilic (lignocellulose material) components.
The absorbing mineral materials (for ex.. kieselgur or zeolies) reduce water activity in the substrate (drying in the final fabrication stage), limiting the bio-deterioration potential, providing the required micro-elements to accelerate the growth of microorganisms in the cultivation stage and reducing the risk of fire.
Using the granular bio-preparation with fungus and bacteria spores allows the material to be fabricated in various shapes, by growing it into molds specially formed for the desired applications, by controlled development on the surfaces it was sprayed along with the growth substrate mixture, by directed in situ cultivation to fill cavities. Directed in situ cultivation provides the ability to repair the thermal insulating materials created using this process, increases its useful life and eco-efficiency.
The final drying of the resulting process down to less than 10% material humidity is meant to deactivate the microorganisms and to provide the thermal and physical characteristics needed for the intended uses.
By varying the lignocellulose and plastic material mixture composition, as well as using different microorganism groupings (fungi forming the spongy mycelium and bacteria that stimulate fungal growth and make the substrate compatible), materials with different properties, for various uses, may be obtained.

Abstract:
The main goal of this project is to reintroduce the recovered polypropylene after its lifetime use in the economic circuit as high performance composite materials. There will be used the current industrial technology for melt alloying of the components. The project task consists in the obtaining of new styrene-isoprene block copolymers with thermoplastic elastomeric properties for advanced recycling of recovered polypropylene. A new technology is proposed for the obtaining of styrene-isoprene block copolymers-recovered polypropylene composite materials with high performance impact strength especially below 0°C. The recycled composite material is cheap and shows higher impact strengths (2-4 times higher) even than the unused initial polypropylene form current production according to our recent experimental results. Therefore, advanced recycling of polypropylene wastes could be ensured with favourable effects for depollution and environmental protection.
The present research focuses on establishing the molecular and compositional parameters for styrene-isoprene block copolymers resulting in recovered polypropylene composites with optimum properties.
The synthesis of styrene-isoprene block copolymers will be done by solution sequential anionic polymerization of monomers with n-BuLi as initiator which permits precise and reproducible block copolymers to be obtained. The molecular weights of the polystyrene and poly-isoprene blocks are well defined with a narrow distribution.
Solution polymerization is a modern non-polluting technique with low water consumption and the solvent is fully recovered at the end of the synthesis of styrene-isoprene block copolymers and then reused. In this way the resource is preserved and the environment is not polluted with waste waters.
These block copolymers will be obtained with certain structures and physico-mechanical properties so that their melt alloying with recovered polypropylene will lead to high impact composites.
