Select Committee on Environment, Food and Rural Affairs Written Evidence


Memorandum submitted by Iogen Corporation

1.  INTRODUCTION/EXECUTIVE SUMMARY

  This submission has been prepared by Iogen Corporation, a Canadian company on the forefront of technology for the conversion of agriculture residues such as straw or dedicated crops including miscanthus or coppice willow into fuel grade ethanol. The company has focused on the UK (as well as North America) over the past four years and has concluded that this market holds substantial promise for their technology.

  Officials in DEFRA, HMT, DfT, and elsewhere have a good appreciation of the technology and our belief in the potential for an EcoEthanol* industry in the UK. From the UK private sector, the Shell Group recently invested £20 million to acquire 22.5% of Iogen.

  *The term EcoEthanol is used extensively in this submission. This is an Iogen trademark and refers to ethanol produced from the cellulose in plant materials such as straw. It is also known as ligno-cellulosic bioethanol.

2.  IOGEN CORPORATION

  One of Canada's leading biotechnology firms, Iogen Corporation, is a manufacturer of enzyme products for the pulp and paper, textiles and animal feed industries, and is a leading developer of technology to make clean fuels from plant fibre. Since it's founding in the early 1970s, Iogen has focused on the processing of natural fibre, and has made a substantial commitment to technology in the field. The company's effort has resulted in a range of enzyme products used around the world to improve the way fibre is processed.

  In May 2002 Iogen signed a £20million strategic partnership agreement with the Shell Group to aid the development of Iogen's EcoEthanol on a global basis. The investment will enable Iogen to more rapidly develop the world's first commercial-scale biomass to ethanol plant.

  Iogen have built a £17 million EcoEthanol demonstration plant in Ottawa, Canada—the only one of its kind in the world. The six-storey 35,000 square foot facility commenced operations in late 2002 and is now converting 45 tonnes of straw to sugar per week on a continuous basis. Production is to increase to 40 tonnes of straw per day by late 2003, with EcoEthanol production commencing this coming summer.

  The technology is rapidly maturing with the construction of the first commercial facility expected to commence in early 2005.

3.  IOGEN AND THE UK

  Iogen's own extensive UK market analysis indicates that there is an excellent opportunity to establish the production and distribution of a cellulose ethanol industry in the UK. Production would be based on cellulose from straw or dedicated energy crops such as miscanthus or coppice willow. The benefits to agriculture and the rural community would be substantial and supportive of related government initiatives.

  Furthermore EcoEthanol could play a significant role in meeting the UK Government's Kyoto Commitments and other environmental initiatives.

4.  POSITION OF THE UK GOVERNMENT

  Iogen is pleased to note the following reference to ethanol from cellulose in the most recent Pre-Budget statement. In response, extensive information has been submitted to involved officials outlining possible areas of support required to move to the commercial production of EcoEthanol in substantial quantities.

    "While the new duty rate will apply to bioethanol produced from any feedstock, the Government is particularly keen to support the development of bioethanol from ligno-cellulosic feedstocks, such as straw or forestry residues, as this looks likely to offer particular environmental advantages. Production of ligno-cellulosic bioethanol is at a comparatively early stage of development, and the Government will therefore consider how best to give it further support." UK Pre-Budget Report, Nov 2002

5.  ENVIRONMENTAL BENEFITS

  As the feedstock for ethanol is frequently straw, this material is available with the expenditure of only a small amount of energy. Given this feedstock benefit and other efficiencies in the production process, studies by the United States Department of Energy, General Motors, and others indicate a much greater reduction in greenhouse gas emissions than conventional ethanol from grain or sugar. While the results of these studies vary somewhat, the consensus is that a litre of Iogen's EcoEthanol has close to a zero net emission of greenhouse gases. In comparison to conventional ethanol the reduction is usually in the order of 1.5 times more effective. Furthermore EcoEthanol along with conventional ethanol has impressive credentials for the improvement of local air quality.

  It should be noted that all automobile manufacturers warrantee their vehicles for up to 10 per cent ethanol blends so these environmental benefits are achievable without any changes to the existing vehicle fleet or indeed to the fuel distribution system.

6.  BENEFITS TO AGRICULTURE

  A full sized Iogen facility will require approximately 700,000 tonnes of straw or dedicated biomass crop feedstock per year. Early indications are that a price of £10 per tonne for straw laying in the windrow is an acceptable price to farmers who expect yields of four to six tonnes of straw per hectare. While this is an immense amount of biomass, a detailed straw survey in the Humber region indicated that after leaving 2/3 of the straw for livestock, other industrial applications and good soil management would still provide an excess of the requirement for a single facility. Hence, without moving into dedicated biomass crops a single Iogen plant would add an incremental £7 million to farmer income in the vicinity of the facility.

7.  BENEFITS TO THE RURAL COMMUNITY

  Besides the direct benefit to the farmer there would be approximately the equivalent of 125 full time jobs related to the collection and transport of the feedstock that increases in value to over £30 a tonne by the time it is delivered to the plant. Furthermore, the direct employment in a combined ethanol facility, co-generation electrical plant and the enzyme unit would be approximately 100 jobs. Beyond this base employment approximately 400 indirect jobs would also be created in the local community. Thus total direct and indirect incremental jobs would reach approximately 600 on a sustainable annual basis.

  During the construction phase of the £200 million project which lasts approximately 24 months, a total of approximately 1,800 direct and indirect job years would be created. It should be noted that the above benefits are for a single large-scale commercial facility. As noted elsewhere in this submission several facilities are eventually envisioned.

8.  OPPORTUNITIES FOR DEDICATED BIOMASS CROPS

  The Iogen process can utilize the cellulose from most grasses, straws, and hardwoods such as coppice willow and chestnut. Miscanthus, with its impressive yields, particularly if grown on marginally productive land, could provide a substantial and stable income flow for farmers. The primary reason that miscanthus has not become an important agricultural crop has been the lack of a substantial market. Iogen could present the commercial opportunity for such dedicated crops. While it is anticipated that miscanthus and straw together would form the feedstock supply in many parts of the country, a full sized Iogen facility could create an equivalent demand for 700,000 tonnes of miscanthus or the production from 35,000 hectares assuming a yield of 20 tonnes per hectare.

9.  ENERGY AND CO -PRODUCTS IN A TONNE OF STRAW/DEDICATED BIOMASS CROPS

  An Iogen facility is essentially a bio-refinery and through converting a tonne of material such as straw the following yields can be achieved.

    —  300 litres of ethanol;

    —  260 kilos of lignin (80% BTU content of typical thermal coal) for electricity production;

    —  commercial quantities of fertilizer, animal feed, CO2, and other co- products.

10.  VISION OF AN ECOETHANOL INDUSTRY IN THE UK

  There is probably sufficient straw with some support from dedicated crops for three 200 million litre EcoEthanol plants, utilizing Iogen type technology. This would provide approximately 600 million litres of ethanol or a universal blend of slightly over two per cent given that current UK petrol consumption is in the order of 27 billion litres on an annual basis. To achieve a 5.75% blend at current petrol consumption levels to match the EU biofuel objective, a total of eight 200 million-litre facilities would need to be constructed. While the ability of UK agriculture to achieve these feedstock requirements has yet to be tested, the opportunity exists for the introduction of an industry that could have a major impact throughout the UK farming community.

11.  INTERNATIONAL BEST PRACTICES

  Feedstock assembly techniques are normally based only on the large ½ tonne bale. While this method has the advantage that it is well tested, it is also expensive. Preliminary work has been conducted in Canada where the baling process is bypassed and the straw is reduced to 1/8-inch particles in the field so it can be handled like grain. This provides an estimated 25% reduction in the cost of the straw delivered to the plant.

  Agriculture machinery manufacturers in North America see the commercialization of the harvest of agricultural residues and biomass crops as a substantial and new business opportunity. Feedstock collection and transport costs are expected to be reduced through the introduction of more efficient collection, handling and transport measures.

  In the US, corn stover, the most abundant of agricultural residues, is plagued by wet conditions at the time of harvesting in late autumn and is thus an unreliable feedstock source. Substantial research is planned in the next two years to develop a system of wet storage similar to conventional silage. While this has its challenges, the similar problems faced by miscanthus may be addressed should this concept emerge as a viable feedstock storage method.

  Miscanthus is a warm weather grass that, in the UK, does well only south of Liverpool. North American grasses such as switchgrass and reed canary grass may be suitable for more northerly regions. Indeed there may be wild grasses and other plants that have yet to be seriously considered that would make ideal dedicated biomass crops. To avoid the negative elements of creating a monoculture with a single dedicated crop, it may be advisable to establish a pool of suitable biomass plants.
