DS Smith makes a major contribution to conserving resources and reducing landfill waste through its position as the leading UK collector of waste paper for recycling and the UK's largest producer of recycled paper. For more information on DS Smith's recycling activities Click Here.
The Group's corrugated and plastic packaging products are made from recycled raw materials wherever it is practicable; 78% of the paper used by the Group's corrugated packaging operations in 2009/10 was recycled paper.
Corrugated packaging is fully recyclable and approximately 80% of corrugated packaging used in the UK is recycled. For more information on corrugated packaging and its recyclability Click Here.
The Group's packaging businesses work with their customers and retailers to optimise the use of resources and reduce waste in their supply chains. For more information on the subject of packaging and the environment Click Here.
Spicers' businesses offer their customers ranges of products with environmentally friendly features such as: products made from recycled or sustainably produced materials; products that are readily recyclable; cleaning products that are safe and biodegradable; electronic products that have low energy consumption.
Environmental Performance
Our businesses continue to take action and invest in order to reduce their environmental impact. During the year, we again employed independent consultants, Bureau Veritas, to review our environmental data collection and reporting process in order to ensure the robustness and accuracy of the Group's environmental performance indicators. This review concluded that overall there was a good level of process control and reporting at the sites but identified some areas for improvement, particularly in relation to the conversion factors being used for converting energy usage into carbon emissions. The recommendations of Bureau Veritas have been implemented. The Group's overall environmental performance in 2009/10 is shown in the table below.

The Group consumed 0.5% more energy in 2009/10 compared with the previous year. This increase was principally due to higher activity levels at the speciality paper mills in the UK and the recommissioning of a CHP plant at one of the mills. The Group's paper mills reduced their energy usage per tonne of paper produced by 0.8%, partly due to the closure of a less energy-efficient paper machine in early 2009. The increase in own use of energy was offset by a reduction in energy purchased by the Group, such that a reduction of 1.5% in total emissions of CO2 was achieved in the year. The Group's total water usage was 4.5% lower than in 2008/09, principally as a result of the closure of the paper machine mentioned above. The total amount of waste generated by our businesses increased by 8.9% partly due to an increase in the proportion of more complex corrugated boxes which give rise to more off-cut waste. Waste sent to landfill was 1.4% lower and the proportion of waste sent to landfill fell to 15% compared with 16% in the previous year.
Energy Efficiency
Our two largest paper mills, at Kemsley in the UK and Kaysersberg in France, which account for approximately 65% of the Group's energy usage, have on-site CHP plants. These CHP facilities provide energy more efficiently, with lower carbon dioxide (CO2) emissions and at significantly lower cost than if it were to be sourced from the external grid. In addition, Kemsley Mill recycles, in the form of energy recovery, a substantial proportion of the reject material, such as plastic and polystyrene, which enters its process mixed in with the waste paper and is separated out during paper manufacture; the mill's own waste-to-energy plant efficiently recovers the energy to produce steam for use in the mill's operations. We are investigating the potential for installing a sustainable energy plant at Kemsley Mill to reduce the mill's reliance on fossil fuels and applied for planning permission for this in April 2010. The proposed fuel for this plant is hard-to-recycle materials, sourced and pre-treated offsite, which might otherwise go to landfill.
DS Smith Packaging, which in 2008 became the first UK corrugated packaging producer to be accredited under the UK's Energy Efficiency Accreditation Scheme, lowered its energy usage per square metre by 1.4%. This was achieved through its division-wide energy management system and a wide range of energy reduction projects. Both DS Smith Packaging and DS Smith Kaysersberg have achieved substantial improvements in their energy efficiency through programmes of process improvements on their corrugator machines.

Methodology: The Group aims to collect and report its environmental data in accordance with the guidelines specified by the Global Reporting Initiative and the Greenhouse Gas Protocol (GHGP), to the extent that this is currently practicable. The figures reported above include data from all of the Group's wholly-owned or majority-owned operations and sites worldwide. The methodology used is consistent for 2008/09 and 2009/10.
1 The energy figures relate to the usage of all fuels used on the Group's sites, plus diesel fuel used for freight transport.
2 The CO2 emissions have been calculated using the energy data, as defined above. The factors used for converting gas, coal, fuel oil and diesel usage into CO2 emissions are the latest factors for each year as published by the UK Department for the Environment and Rural Affairs (DEFRA) in the Guidelines to DEFRA's GHG Conversion Factors; the factor used for converting gas usage changed from 0.19 tonnes of CO2 per megawatt hour in 2008/09 to 0.18 tonnes of CO2 per megawatt hour in 2009/10. The factors used for converting electricity usage are the national figures for each country in which the Group operates sourced from the International Energy Agency Data Services via the UK Carbon Trust; these factors therefore reflect the mix of fuels used for electricity generation in each country. As required by the GHGP, Scope 1 and Scope 2 CO2 emissions are reported separately. Scope 1 (direct) emissions are those arising from combustion of fuel in installations or vehicles owned by the Group; Scope 2 (indirect) emissions are those arising from bought-in energy (ie electricity or steam) where the combustion has been carried out by another company. The 2009/10 Scope 1 emissions included 57,000 tonnes (2008/09: 61,000 tonnes) of CO2 which were associated with the production of electricity which was sold to the grid from one of our CHP plants. Scope 3 emissions from sources external to DS Smith but involved in the supply chains for the Group's products and services are not included.
3 Water discharge figures relate only to the Group's paper mills, which account for approximately 95% of the total water usage of the Group. The quantities measured, in accordance with the requirements of the IPPC regulations, are for process water only and do not include cooling water. 73% of the water discharged was to the sea, 17% was to rivers and 10% was to sewers.
4 The waste figures relate to waste generated by our operations; they do not include waste that is collected from external sources for recycling within our paper and plastic packaging operations. The data on waste identifies separately: a) the amount of waste that is conventionally recycled in the manufacture of other products, b) the quantity of waste cellulose fibre, generated in the paper-making operations, which is recycled through agricultural use as landspread, c) the quantity of waste that is used for energy recovery at our waste-to-energy plant, and d) the waste that goes to landfill.
