The above estimates are synthesised from multiple reputable sources and methodologies in the field of life cycle assessment (LCA) and embodied carbon studies, including: Inventory of Carbon and Energy (ICE) Database (University of Bath), Carbon Trust Reports and Guidelines, Environmental Product Declarations (EPDs), Academic and Industry LCA Studies, Industry Benchmarks and Sustainability Guidelines
The above estimates are synthesised from multiple reputable sources and methodologies in the field of life cycle assessment (LCA) and embodied carbon studies, including:
These estimates are not exact measurements for every case but rather ballpark figures based on an aggregation of data from the sources above. Actual embodied carbon can vary depending on design specifics, material choices (such as sustainably sourced timber or recycled steel), production efficiencies, and the precise refurbishment processes employed. For detailed, product-specific analysis, a full life cycle assessment (LCA) using actual manufacturing and refurbishment data would be necessary.
This synthesis provides a general overview of the typical carbon savings achievable through refurbishment compared to new production.
4.1 Light Iron Recycling
The recycling of light iron, which is often a term for thin-gauge steel, can result in significant energy savings and therefore carbon emissions reductions when compared to producing steel from raw materials. The carbon savings from recycling steel come from a few different areas:
Energy Savings: The energy required to melt and reuse scrap steel is much less than the energy needed to produce steel from iron ore. Recycling steel uses about 60-74% less energy compared to producing steel from virgin materials.
Reduction of Carbon Emissions: Using less energy means that fewer fossil fuels are burned, which directly leads to lower carbon emissions.
Resource Conservation: Recycling steel conserves the raw materials (iron ore, coal, and limestone) that would otherwise be used to make new steel. This in turn reduces the carbon footprint associated with extracting, transporting, and processing these materials.
The exact figure for carbon savings can vary based on several factors, including the efficiency of the recycling process and the type of energy used. According to some estimates, recycling a ton of steel can save around 1.8 tons of iron ore, 0.6 tons of coal, and 0.05 tons of limestone. The CO2 savings are typically estimated at about 1.3 kilograms of CO2 per kilogram of recycled steel.
Using this rough estimate, recycling 1 kilogram of light iron could save around 1.3 kilograms of CO2. So, for example:
These figures are approximations and can change based on technology, the mix of energy sources used in the recycling process (e.g., the amount of renewable energy), and the specific processes at the recycling facility. Additionally, the carbon benefits of recycling can also depend on the transportation and collection efficiencies, since moving the scrap metal to recycling facilities also consumes energy.
4.2 Polypropelene (PP) & polyamide (PA6GF)
Recycling plastics like polypropylene (PP) and polyamide 6 with glass fiber (PA6GF) also conserves resources and reduces greenhouse gas emissions compared to the production of virgin plastics. The specific amount of CO2 saved can vary depending on the recycling method, the efficiency of the recycling process, and the source of energy used in the process.
For polypropylene (PP), estimates for CO2 savings from recycling can vary widely, but to give a rough idea:
For polyamide 6 with glass fibre (PA6GF), the calculations are more complex due to the additional processes involved in handling the glass fibre component. However, the principle remains that recycling this material is generally less energy-intensive than producing virgin PA6GF. The exact CO2 savings would depend on many specific factors, including the efficiency of separating the glass fibre from the polymer, the quality of the recycled material, and the subsequent applications.
There is less data readily available for the specific CO2 savings from recycling PA6GF, but considering that glass fibre reinforced plastics often require more energy to produce, the savings are likely to be significant as well, possibly in a similar range to or higher than PP when considering the full life cycle of the material.
For more precise data, you would need to refer to life cycle assessments (LCAs) for these specific materials, which take into account all stages of the product's life - from production through to disposal - to determine the total carbon footprint and potential savings from recycling. Manufacturers of these plastics may also provide specific data based on their proprietary recycling processes.
4.3 Melamine Faced Chipboard Recycling
Melamine-faced chipboard, often used in furniture and cabinetry, is composed of wood chips bonded with a melamine resin, which is a type of plastic. Recycling or repurposing it is more challenging than recycling untreated wood due to the resin content. However, when melamine-faced chipboard is recycled as biofuel — usually in waste-to-energy plants — it can offset the use of fossil fuels, leading to savings in carbon emissions.
The carbon savings from using melamine-faced chipboard as biofuel would come from two main areas:
Displacement of Fossil Fuels: When used as biofuel, the chipboard's energy content displaces that of the fossil fuels it replaces. Wood products are considered to be carbon-neutral over their lifecycle, assuming that the carbon released during combustion is offset by the carbon absorbed by replacement tree growth. The resin component, being a fossil-based material, would not be carbon-neutral, but it would still potentially offset fossil fuel use.
Avoided Methane Emissions: If the melamine-faced chipboard were to end up in a landfill, it could decompose anaerobically and produce methane, a potent greenhouse gas. By recycling it as biofuel instead, these methane emissions are avoided.
The exact carbon savings would depend on several factors, including:
A general estimate for wood as biofuel suggests that 1 ton (1,000 kg) of dry wood used as fuel can displace around 0.8 to 1.1 tons of CO2 emissions that would have resulted from coal. Since melamine-faced chipboard is not entirely wood (due to the resin content), its energy content and carbon displacement per ton would be slightly less than that of pure wood.
For a more accurate assessment of the carbon savings from recycling melamine-faced chipboard as biofuel, you would need to know the specific energy content of the chipboard, the proportion of melamine resin to wood, and the type of fossil fuel being displaced. Life cycle assessments (LCAs) tailored to the particular waste-to-energy facility and the specific type of chipboard being processed would provide the most precise figures.
4.4 General Waste or Refuse-derived fuel
Refuse-derived fuel (RDF) is created from various types of waste that are not suitable for traditional recycling, including non-recyclable plastics, paper, cardboard, and wood. The waste is shredded, dehydrated, and sometimes pelletised or fluffed to improve its consistency and burning properties. RDF is used as a replacement for fossil fuels in power generation and in industrial processes such as cement kilns.
The CO2 emissions savings from using RDF depend on several factors:
Composition of the RDF: Since RDF is made from a mixture of waste materials, its composition can significantly affect its energy content and the emissions associated with its combustion. Materials with a higher plastic content, for instance, will generally have a higher energy content and might produce more CO2 when burned compared to materials with a higher proportion of biogenic (plant-based) content.
Type of Fossil Fuel Displaced: The CO2 savings will also depend on which fossil fuel the RDF is replacing. For instance, natural gas has a lower carbon content per unit of energy compared to coal. Displacing coal will generally result in higher CO2 emissions savings.
Energy Efficiency of the Process: The efficiency of the energy recovery process impacts the net CO2 savings. Modern, high-efficiency incinerators that capture the energy generated for electricity or heat are more beneficial in terms of CO2 savings.
Carbon Neutrality of Biogenic Content: The plant-based portion of RDF is often considered carbon-neutral because the carbon released during its combustion was recently captured from the atmosphere during the plants' growth, assuming that more biomass is grown to replace it.
Considering these factors, general estimates suggest the following:
Coal Replacement: Burning RDF instead of coal can save between 0.8 to 1.1 tons of CO2 per ton of RDF used because coal has higher carbon emissions per unit of energy produced.
Natural Gas Replacement: Natural gas has lower carbon emissions per unit of energy, so using RDF in place of natural gas would result in lower CO2 savings.
In Europe, where RDF use is more common, the average CO2 emissions savings are estimated to be around 0.5 to 0.8 kg of CO2 per kg of RDF used when replacing coal. This is a broad estimate and actual savings could vary based on the specific conditions mentioned above.
It's important to note that while RDF can save on CO2 emissions compared to fossil fuels, there are other environmental considerations such as the potential release of pollutants and the need for effective emissions control systems to minimise any harmful impacts from combustion.

The circular economy is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended. Here is a list of key terms and their explanations:
Understanding these terms provides a more nuanced view of the different phases of product lifecycles and the strategies for sustainability in each phase within the circular economy framework.
The disposal of such large quantities of office furniture has multiple environmental implications:
Considering these factors, there is a strong argument for more sustainable practices in the management of office furniture at the end of its lifecycle. Initiatives might include:
The figures provided by WRAP, if recent and accurate, should serve as a call to action for businesses, policymakers, and waste management professionals to develop and support initiatives that address this issue. Collaboration across sectors can lead to innovative solutions that keep office furniture out of landfills and in productive use for as long as possible.
The situation described by WRAP, with significant volumes of office furniture such as chairs and desks ending up in landfills, presents a substantial opportunity for expansion in the third-party remanufacturing and refurbishment sector. This sector can play a crucial role in a more circular economy by extending the life of office furniture. Here’s how:
By seizing these opportunities, third-party remanufactures and refurbishers can significantly reduce the environmental impact of office furniture waste, support the transition to a more circular economy, and build a robust market for sustainable office furniture solutions.
