Advanced oxidation processes in industrial wastewater treatment (AOPI). Funding period: 2012-2016. Wastewaters contain often organic solvents and degradation products which are harmful and toxic. This has led to stricter regulations related to wastewater. Therefore, efficient abatement methods are required. In addition, more information on long-term health effects should be developed. Project aims at studying advanced oxidation processes in the treatment of wastewaters from pharmaceutical and food industry. For these waters no economical and technically viable solution exists. The idea is to develop a hybrid process that uses first photocatalysis to decompose large organic molecules and then to mineralize the rest at higher temperatures and pressures. Focal task is to find a catalyst suitable for both reactions. Furthermore, economic, societal, environmental and health effects are evaluated. The efficient wastewater treatment is a step towards closing the water cycles in industry and to sustainable water use. The success of the project requires multidisciplinary approach.

Biomass value chains - New chemicals, growth and business from biomass. European Commission seeks new economic growth, which strongly supports sustainable development and promotes towards the low carbon economy. Therefore, bio-based chemicals, e.g. building blocks for bioplastics, have been raised at the center of the 'Europe 2020' strategies. These biomass-based building blocks, monomers of bioplastics, offer huge market and growth potential since they can be used for partial replacement of fossil-oil based plastics. Further, from the competitiveness viewpoint of Finnish industry, biomass-based high-value end products should be preferred instead of energy use.
Lignocellulosic biomass is heterogeneous, and its processing is challenging. In principle, biomass is logistically expensive, and e.g. biofuel production suffers from high production costs and low value of end product. Therefore, more selective pretreatment procedures are required which enable chemical production of cleaner fractions and high-value end products, such as bioplastics monomers, such as polyols and functional organic acids. This value chain also enables a profitable new business in the rural areas from local biomass. By integrating chemical processes to existing energy production and industrial parks, cost-efficient solutions are possible to build.
Main stages of this project are: efficient and selective pretreatment of selected biomasses, characterization of biomass fractions in the different stages, preparation and characterization of catalysts, catalytic conversion of C5 and C6 sugars (cellulose and hemicellulose derivatives) and direct conversion of cellulose to high-value end products (monomers of bioplastics etc.), and results evaluation and reporting. Expected main results are: new knowledge on biomass pretreatment and catalytic conversion, new and innovative uses of lignocellulose derived sugars, and new technological solutions for the production of bioplastics monomers.

Improvement of oil spill prevention with green chemicals (VIKE). Funding period: 2015 – 2018. The main purpose of this project is to produce novel green chemical oil spill response concepts based on natural polymers, cellulose and chitosan, in the sea near to the coast and harbors, and in the soil for example in storage areas. Cold and windy weather and ice contained water make the oil spill response demanding in the arctic conditions and it has created a growing need for the development of the response to oil spills in the arctic coast areas. Chemical methods in the oil spill response are usually effective for the oil spills that are spreading in the coast but used chemicals are mainly toxic. Thus, their use is not recommended. The Finnish know-how in the mechanical oil spill response in arctic conditions is wide ranged, but there are no chemical suppliers who could complement the mechanical response with novel biochemical. Anyhow, there is an international demand for bio-based chemicals since, for example Sweden and England have banned many used chemicals. The aim of this project is to produce non-toxic bio-chemicals which can be dispersing agents (break oil down the small droplets) or herding agents (thicken the thin oil slick sufficiently). In addition to, the purpose is to produce novel effective adsorption materials from cellulose and chitosan, which can be used immediately after the oil spill.
The target groups for novel oil spill chemicals are the authority of the oil spill response and commercial agents who transport and store in the harbors. VIKE- project improves the efficiency of the oil spill response and makes it more environmentally friendly in the harbors, sea routes close to the cities and storage areas. This project creates new concepts and establishes the Finnish know-how and competitiveness in the commercial activity in the arctic oil spill response. The effective green oil spill response chemicals are a new business area for the chemical manufacturer (small and medium-sized enterprises and big companies: forestry companies and special chemical companies), which confirms the Finnish know-how in the oil spill response and may also promote to the establishing of the competence center of the arctic oil spill response (Oulu has been one of the candidates in the location of the center). Produced chemicals in the project are bio-based and therefore environmentally friendly. Also, the production costs are competitive to present chemicals used. The combination chemical-mechanical response of oil spills creates more commercial potential to the manufacture of the method, who can promote the market for its concept and enable future development for arctic sea conditions. As a result, there will be a fast oil spill response method, which is based on the combined chemical-mechanical response that supports the development of arctic oil spill response know-how and enables business opportunities and competitiveness in the field.
The VIKE-project improves the safety of the arctic logistic activity near to the coast (sea routes close to the cities, harbors and storage areas). The new concepts increase the efficiency and ecology of the oil spill response. The project will create new concepts and endorse the Finnish know-how of oil spill response and business competitiveness. Contact information: Prof. Mirja Illikainen, Dr. Ossi Laitinen
Novel high-performance wood and cellulose biocomposites (BioComp). Funding period: 2015 – 2019. Biocomposite materials are mixtures of polymers and reinforcing fibres that result in tailored material characteristics such as the combination of good mechanical properties and low weight. A large variety of potential applications can be recognized from high-tech products to bulk consumables. Biocomposites promote the economically, environmentally and socially viable use of natural resources by increasing added value of the production chain, both in local and export markets. Due to the ever-increasing environmental awareness of consumers about limited natural resources and the risk of climate change, there is a continuously increasing demand for new high performance biocomposites for applications in packaging, construction, furniture, electronic appliances, biomedical materials, and the transport industry, for instance.
Novel high-performance wood and cellulose biocomposites FiDiPro research project is expected to lead to:
- Development of new solutions for forest and biomass-based composite materials with enormous economic potential, yielding products with a performance equal to or better than those materials in use today.
- Customer-oriented novel technologies for processing biocomposites with controlled morphology and properties to be used as high value export products for the Finnish bio-based industries.

Plasticized cellulosic composites for packaging materials (COMPAC). Funding period: 2014 – 2016. Wood containing composites have been successfully introduced to large variety of application like WPC (Wood Plastic Composites) panels. However, these materials still contain high amount of non-renewable raw materials despite the plastic substitution with e.g. PLA has shown good results. Furthermore WPC material production is made with plastic production equipments e.g. pelletizing and extrusion technologies. COMPAC aims to integrate production of composite material into a conventional reel to reel paper and board making processes with minor changes. The innovativeness is in the pre-modified fibre material, which can be produced as a sheet-like material offering very large variety of applications to be used in. In comparison to existing vulcanization techniques with sulphuric acid or zinc chloride the COMPAC develops more environmental friendly chemicals modifications for the fibre material. Economically feasible biomaterial solution needs also to be producible in high amounts from abudant natural resources, for this reason wooden materials are preferred and producible for industrial applications with low processing costs. Developing novel chemical fibre treatment method to ‘plasticize’ or ‘chemically refine’ fibres gives them valuable product properties and can be implemented into new or existing board machine approach flow systems to upgrade machines for plasticized cellulose processing. The product resulting from this chemical treatment will be lighter and stronger, and it will resist more moisture and offer better barrier properties than the present liner and fluting grades.

Towards Efficient and Sustainable Arctic Oil-Spill Response: Green Dispersing and Herding Agents Derived from Northern Bioresources (ArcRespo). Funding period: 2014-2018. Ecosystem at the Arctic regions is highly vulnerable and slowly recoverable and therefore disasters, such as oil-spills, would be extremely catastrophic. Due to the increase of oil activities and risks for the oil-spills accidents at Northern region, oil-spill response is one the most crucial items when considering sustainable use and refining of Arctic natural resources. The aim of the present research is to investigate aspects of production and use of new efficient and sustainable chemical oil-spill response techniques for the Arctic conditions.

Utilization of green chemicals in non-energy extractive industries (Celmin). Funding period: 2014-2016. At mining sites, there are many potential sources (e.g. dressing plant, tailing ponds, ore stockpiles, waste rock dumps and heap leach piles) for the toxic pollution of surface waters and buildup of possible toxic sediments downstream natural waters causing by process effluent discharge, seepage, rainfall and snow melt. Although the main amount of dissolved solid substances in waters originates from ore, a small amount of pollutants comes from oil-based chemicals used in flotation as well as other metal concentration processes and dewatering, possible creating toxicity problems when released in effluents. Thus, the purification of waters coming from both extraction and mineral processing during mining activities is needed. Also mining-closure and rehabilitation issues have to take into account because acid drainage, for instance, is generated at both abandoned and active mine sites when sulphide ore waste is exposed water and oxidation. The CELMIN project aims to develop concepts for environmental-friendly effective green chemicals by chemical modification of nanofibrillar cellulose (NFC) to be functional in mining applications responsible for dissolved and suspended solids load.The results of the project is expected to increase sustainability of primary resource supply by decreasing water pollution of mining industry, lower carbon footprint by using renewable raw materials instead of a fossil feedstock in chemical production and lessen concern about environmental issues by using biodegradable chemicals in dressing of ores and water purification.
