1 Development of innovative products made of flax chaff for adsorption of oil spillage Akobuije Stanley IGWE, MSC PIDSupervisor: Dr Elena SazhinaMotivation: 2009 is the Year of Natural FibresInternational Conference on Natural Fibres 2009Institute of Materials, Minerals and Mining,London, UKUrgency of the problem under consideration: BP disaster in Mexican GulfObjectivesTo critically assess existing knowledge on products made of natural fibres, and in particular for adsorption of crude oil spillageTo propose new products made of flax chaff and natural fibres and to assess their manufacturing costs, environmental impact and marketing nicheTo design and manufacture working prototypes and to evaluate their propertiesProposed product:The project aims at developing Oil Adsorption Mat using flax chaff.It is designed to utilize the oil-adsorption property of Flax chaff to clean up oil spillage by placing the Adsorption Mat on top of oil and allow it to soak the oilThe proposed adsorption mat is made up of chaff wrapped in a plastic bag with openings to allow the adsorption process.After the adsorption the oil can be recovered and processed.Novelty of the product: An innovation to explore the economic and commercial value of the flax chaff viaCreating a product to solve urgent oil spill problemThe product is based on flax chaff that is growing abundantly in many areas such as Northern FranceFlax chaff currently is a waste product.The target market will be oil production industries, such as BPREVIEW OF EXISTING KNOWLEDGEPasila (2004) Marine Pollution Bulletin 49 (2004) 1006–1012:A brief description of the adsorption fliter technology developed in the paper:‘Oil residues can be cleaned from water by running it through a simple filter made from freeze treated, dried, milled and then fragmented plant material. It is possible to produce filters, which pass water but adsorb oil.Fine spring harvested hemp fibre (diameter less than 1 mm) and reed canary grass fragments adsorb 2–4 g of oil per gram of adsorption material compared to 1–3 g of water.Brainstorming of ideas and feedback:presentation at the INTERREG FLAX workshop on 28 May 2010Discussion and ConclusionThe oil adsorption mat is easy to use. Its prime manufacturing cost is low. Also flax chaff is a waste product and therefore will cost less. Its transportation will add little cost because it is light and thin compared with FrogmatIt is environmentally friendly because it is biodegradable .Its unique selling price is cost efficiency and being made of renewable materialsIts market niche is seen as open sea spills contrary to Frogmats for coastal areasIts market size is big; there is daily occurrence of oil spillage.Its demand will be high because most of the existing product for cleaning oil spillage are complex and expensiveRecovering oil from the adsorption mat may follow Frogmat technologyLCA options may include either reusable or disposable versions of flax matThe product is at the stage of developing a methodologyfor effective adsorption of large-scale oil spillages.Business assessment:Production costs of flax chaff are low because this is a byproduct of flax fibresProcessing costs are assessed against existing production procedure of straw Frogmat .Links to Frogmat company at Isle of Wight are sought with the help of Business Development Manager of SET, UoBEnvironmental impact and Life Cycle AnalysisGrowing flax plants reduces carbon dioxideThe flax products are biodegradable after useful lifeAlternative products for oil spill cleanup:Acknowledgements:Many thanks to the INTERREG FLAX team at theSchool of Pharmacy and Bimolecular Sciences.l thank Mr Bill Whitney for technical help,.Dr Steve Plummer, Mrs Zoe Osmond the BDM of SET, UoB,and the supervisor are thanked for their kind assistance.Oil spillage absorbent granulesSlick sackRakingJoanna Lumley and the FROGMAT made of straw
