A warm welcome to all of you for the 6th Unilever-RSC International Symposium this year entitled Innovation in
Sustainability: Air, Water and Materials. Unilever is one of the top fast moving consumer goods companies in the
world with annual sales of nearly €50 billion and a high ranking amongst Fortune Global 500 and FTSE 100 companies. Today Unilever defines its purpose as "Make Sustainable Living Commonplace" and it was one of the first companies in the world to tie a growth agenda to a corporate commitment to sustainability. Many of the big challenges of sustainability demand new science and technology to bring forward the most effective solutions worldwide. Challenges such as air pollution/poor quality air, scarcity of fresh water and increasing waste due to material consumption are fast becoming major problems facing not just companies, or countries, like China, but in fact the entire world population. Problems of this magnitude and impact present opportunities for innovation too. And this was the inspiration behind the theme of this year's symposium. Unilever came to China in 1923 and established its first operation in Shanghai, manufacturing and selling Sunlight and Lux soap bars. History moved on, and as China re-opened its door, Unilever re-entered China in 1986; and has since cumulatively invested more than $2 billion to grow its business. Today, we have built up a dynamic and fast growing business. Our most successful global brands, e.g. Omo, Dove, Lux, Clear, Lifebuoy, Pond's, Comfort, Lipton, Knorr, LYNX, Rexona, CIF, Wall's and Unilever Pureit, as well as some local brands, e.g. Zhonghua and Hazeline, have become well known and preferred among Chinese consumers. As one of the largest consumer markets, China is of high strategic importance for Unilever. To fulfil our ambitious growth goal in China requires us to fully understand the needs of the Chinese consumers, and to develop advanced technologies to meet their needs. As one of six global R&D laboratories, Unilever Research China was formally founded in October 2003. In September 2009, a new R&D centre, with an investment of €50m was officially opened in Shanghai Linkong Economic Development Zone. It has become one of the major global innovation centres of Unilever with world-class capabilities in research and development for all Unilever business. Research is particularly strong in chemistry and functional materials science with a clear focus on the discovery of novel particles, polymeric and natural materials, and their application in Personal Care products.
Our people are the most valuable assets of the R&D centre. We are building a dedicated and outstanding team of young scientists, full of energy, enthusiasm, creativity and confidence. They have top qualifications and expertise; most are graduated in China and more than 60% have overseas work experience; we also have a great gender balance, in fact, more than half of our team are women scientists. We nurture a culture of ‘delivery to the marketplace'. In such a culture people are highly motivated to energetically drive their innovation programmes. They are encouraged to think and work in varied ways, in order to develop break-through technologies of great worth. We have built an outstanding external network in China, to supplement our extremely broad and well established Global network. We have close, trusting and productive collaborations with leading academicians from China's top Universities and Governmental Institutes.
Taking all these aspects together, our laboratory has consequently invented a wide range of new materials. The novelty of our work has resulted in a large number of patents and publications. Some of them have already been used successfully in new products, despite the short history of our laboratory, and they are adding great value to both our consumers and our business. Today, we all strive to build our laboratory into the best in the industry; and to develop more and more technical breakthroughs to catalyse the value we can bring to consumers around the world through bigger, better and faster sustainable innovation. Unilever are proud to again be supporting this series of exciting one day meetings and sincerely thank our hosts and local organisers at Fudan University for all their help in arranging the meeting. We also thank each of the speakers, poster presenters and participants – without whom there would not be a symposium! We very much hope you will be stimulated by all the presentations and I very much look forward to meeting you.

Future of wastewater treatment with a focus on hazardous chemicals
Cranfield University, UK Due to the increasingly stringent regulations and wider ranging legislation relating to water and the environment the drive now is to determine appropriate control measures which can include the removal of hazardous chemicals during wastewater treatment. Secondary wastewater treatment as currently configured is not designed to remove hazardous chemicals, although they do so fortuitously. Enhancing the removal of hazardous chemicals by these existing wastewater treatment infrastructures is highly desirable due to the high potential capital costs required for the construction of alternative/additional treatment technologies. Activated sludge is a widely implemented existing treatment process offering a relatively sustainable approach with lower consumable outputs. Operational parameters which are modifiable and impact hazardous chemical removal include solids retention time (SRT) and hydraulic retention time (HRT). Producing a strategy which could optimise the removal of hazardous chemicals by activated sludge needs to encompass a chemically diverse range of hazardous chemicals encountered in wastewaters; ranging from conservatively biodegradable organics to non-biodegradable inorganic species. Such a wide variety of organic and inorganic chemicals offer extremities in physico-chemical properties. This causes their fate and behaviour to vary significantly during wastewater treatment making optimisation of their simultaneous removal difficult. The presentation will examine control measures for hazardous chemicals including their removal in wastewater treatment processes and future wastewater treatment flowsheets.

The smoke particles are composed primarily of carbonaceous materials and a considerable amount of inorganic salts ( 25 wt. %). During aging, the fraction of inorganic salts in smoke PM increases, mainly due to the formation of more sulfate and nitrate at the expense of chloride; this heterogeneous conversion is of fresh smoke particles is 0.27 and this is estimated to decrease by 0.01 after 4 h dark aging. Both aging and high RH lead to increases of particle size and density. The effective densities of smoke PM and PM deduced from concurrent mass and volume concentration measurements gradually increase from about 1.18 to 1.44 g/m3 within 4 h aging at 45%–55% RH, in line with the results obtained both from size-resolved particle density analysis using an aerosol particle mass analyzer (APM) and from estimation using composition-weighted bulk densities. The density of smoke particle is size-, RH-, and aging extent-dependent; the size effect becomes less pronounced Keywords

Towards a circular economy using green chemistry
Green Chemistry Centre of Excellence, University of York, UK Increasing demand for consumer goods from an increasing world population is placing enormous strain on the resources needed by the worlds manufacturing industries. Traditional resources have often been from non- renewable sources located in relatively accessible regions but these are finite, their exploitation non-sustainable and they are becoming scarce. At the same time, the wastes generated in manufacturing and in use of the articles of today's society have been allowed to accumulate in rapidly filling landfill sites or disposed of in other environmentally harmful ways. The Circular Economy seeks a closed loop approach to the twin problems of resource and waste by making the latter the solution to the former – waste is the future resource. The most interesting of the large volume wastes is bio-wastes including forestry and agricultural by-products, and food supply chain wastage. To fully exploit the concept and make it widely useful while maintaining environmental advantage, we need to use Green Chemistry. New, energy efficient conversion technologies that can convert a wide variety of waste streams into valuable chemicals and energy include low-temperature microwave processing, benign solvent extraction and the use of mesoporous solids to capture metals from waste streams (including via the use of plants to help concentrate the metals). The integration of thermo-chemical and bio-chemical technologies will become increasingly important as we seek to increase the efficiency of biomass conversion.
A wide range of projects will be described to help illustrate how we can apply green chemical technologies to the valorisation of wastes. These projects are usually carried out in consortia often involving industry and on many occasions ranging across more than one country. Our COST Action of Food Waste Valorisation (http:// costeubis.org) is a good example of how we can draw together a diverse range of skills and disciplines to help tackle common challenges such as food waste and diminishing traditional resources. Our new international green chemistry centres network (http://g2c2.greenchemistrynetwork.org) helps create multinational partnerships that can meet new opportunities for tackling global challenges.

VP Strategic Science Group, Unilever plc. This contribution presents an overview of Unilever as one of the foremost global multinational companies in the fast moving consumer goods (FMCG) sector which has tied a growth strategy for its business to a corporate commitment to sustainability. It outlines Unilever's essential credentials for sustainability showing how through its history and with the core values of the company it sets a new norm for responsible enterprises. Unilever's programme for addressing sustainability is embedded in the Unilever Sustainable Living Plan –a comprehensive action-plan to reduce its environmental imprint and to increase its positive social impact enabling a responsible and thriving business. Insights are delivered on the key problems which are faced not only by major companies like Unilever but by many companies, governments, countries and the entire human race resulting from an increasing global population, increased demand for energy ,water and food supply all against a backdrop of serious climate change. All of these factors will conspire in the future to push beyond the planetary boundaries for available resources and need practicable and innovative thinking to bring solutions for water shortages- not just for potable water but for washing, essential for health and hygiene. We need to address the mounting problem of waste-leftover or by product materials the quantity of which scales with global population growth and consumerism and to tackle the increasing threat to the quality of the very air we breathe due to pollution arising from ever expanding industrialisation and population growth. Within these BIG problem domains there are focal points for the FMCG industries to address for which solutions are only possible through the power of new science and technology. This expose sets the scene for the chosen theme of this year's entire Unilever-RSC symposium.
Properties of green solvents and their application in green chemistry
Institute of Chemistry, Chinese Academy of Sciences, China Green chemistry is very important for the sustainable development of our society, which has received extensive attention. In this lecture I will give a brief introduction about green chemistry in China. At the same time, I would also like to discuss some recent works in our group on properties of green solvents and their application in green chemistry1-17, which include mainly: 1) phase behavior and intermolecular molecular interaction in complex supercritical fluids (SCFs), ionic liquids(ILs), CO /IL, CO /water, IL/water systems; 2) chemical reactions and material synthesis in green solvent systems.

Sustainable wastewater treatment in China: Challenges,
opportunities and emerging technologies
Yongmei Li, Ai Zhang, Jie Wang, Qian Ping, Jinte Zou State Key Laboratory of Pollution Control and Resources Reuse, College of Environmental Science and Engineering, Tongji University, Siping Road 1239, Shanghai, China 200092 Corresponding author: Yongmei Li Wastewater is no longer a waste, but a kind of resource, such as water resource, carbon source and nutrient source. Nowadays, sustainable wastewater treatment is the choice in the world. The purpose of this study is to introduce the present situation and prospect of wastewater treatment in China. First, water pollution problems and the general wastewater treatment in China are reviewed. Second, challenges and opportunities of China are discussed based on the requirement of sustainable wastewater treatment. Finally, some emerging technologies for wastewater treatment and resource recovery are introduced. Strategies are also suggested for the development of wastewater treatment in China.

Development of surrogates to predict photochemical fate of PPCPs
Department of Environmental Science and Engineering, Fudan University, China The photochemical fate of PPCPs in the aqueous environments is an emerging concern for environmental scientists and engineers. The effluent from wastewater treatment plants is the major point source for PPCPs and its releases with EfOM together. In the current study, photo-degradation of twenty-three PPCPs was examined in the effluents under solar simulated irradiation. Radical scavenger, nitrogen saturated, isotopic effects experiments have been employed to elucidate the degradation mechanisms. Direct photo-degradation, 3EfOM* and hydroxyl radical are three major involved removal processes. With photo-degradation of trace levels of PPCPs, UV-vis and excitation-emission matrix (EEM) fluorescence spectroscopy of the effluents, also gradually reduced. Therefore, both water parameters have been identified as appropriate surrogates to assess the photo-degradation rates of PPCPs. Tyrosine-like EEM peak is associated with OH radical dominated PPPCs, such as trimethoprim, caffeine, ibuprofen, gemfibrozil, triclocarban, atenolol; UV, tryptophan-like peak and UV-humic-like peak are three parameters associated with 3EfOM* dominated PPCPs, including sulfamethoxazole, amoxicillin, roxithromycin, metoprolol, propranolol, carbamazepine, naproxen, ractopamine; Visible humic-like peak is associated with direct photodegradation dominated PPCPs, including metronidazole, ornidazole, dimetridazole, famotidine cimetidine. The decrease in the UV and EEM fluorescence correlated well with the removal of PPCPs. These results suggested that these water spectroscopies may be suitable surrogates for monitoring the photo-degradation of PPCPs in effluents. discount on all books for Royal Society of Chemistry members Choose from over 1,000 high-quality interdisciplinary, professional, expert books that detail the latest research advances and highlight technology, reference information, opinions and perspectives in modern science.
