Eco worktopsGreening your kitchen - Part 2The following eco worktops article looks at the current range of kitchen counter tops / worktops / work surfaces, giving you an overview of alternative materials available. Going green in your kitchen is not as difficult as you imagine, the range of materials and products are every growing as the demand for healthier, greener and more sustainable alternatives continue.
Recycled content worktopsRecycled plasticA solid worktop made from between 50 - 100% post consumer and manufacturing waste plastic (e.g. yogurt pots, coffee cups, plastic bottles). Advantage is that the recycled plastic content would be destined for landfill sites if not recycled. The nature of the recycled content creates a unique fleck. A highly durable finish with good wear and tear properties. Some recycled plastic worktops can be re-sanded if scratches are present and at the end of the lifecycle some types are recyclable into lower grade plastic products. Product may become flexible overtime with possible warping. Sinks and drainers can be moulded to be seamless within the worktop.
* As with all plastic based materials, consider the levels of dangerous VOC emissions released over the material lifetime which lower the air quality in your home and are linked to ill health.
Recycled laminates
Recycled paper, glass dust and fly ash
Recycled glass
Recycled / reconstituted stone
Fly ash and recycled waste carpet fibre
Masonry worktopsNatural stoneIt is important to note that natural stone like granite and slate are non renewable materials. Aggressive raw material extraction through mining, the manufacturing process and heavy weight of stone during transportation means high levels of embodied energy. Hard stone like granite have higher levels of embodied energy than soft stones like soapstone which is nearer to the surface of the earth and does not require aggressive quarrying. No VOC emissions and fully recyclable into block or slab form. A highly durable product which is easy to maintain. Some sealants required for porous stone like granite to prevent staining.
Manufactured worktopsConcreteTo lower embodied energy levels source a local supplier and retailer. Specify fly ash as an alternative to cement which has high levels of embodied energy during the manufacturing process. Sealants are needed to prevent staining, once applied concrete is easy to maintain and clean. Minimal VOC emissions if non toxic additives are used. Finished material retains a cool temperature which is ideal for baking and making pastry. Excellent durability. Finish can be combined with recycled glass for an alternative visual effect. Concrete can be recycled into lower level materials.
Tiles
Terrazzo
Paper stone
Timber worktopsEco worktops made from wood. To be truly eco the timber sources must come from sustainably managed forests check for certification before purchase. Alternatively sourcing a locally harvested and manufactured timber reduces the need for transportation and distribution which lowers the level of embodied energy. If possible specify both local and certified sustainable timber for worktops. Ideally use reclaimed timber from a salvage yard. Wood requires little processing, is a natural, renewable and 100% biodegradable material. Material can be recycled into blocks and slabs. Adhesives can be avoided with fixings and fittings. Appearance is polished and smooth with a unique wood grain either solid wood, blocks or veneers. Can scratch and burn re-sanding can be done throughout the lifecycle. Ongoing maintenance is required regular sealing with oil or wax to keep the timber water resistant and to prevent splitting.
Timber alternative worktopsEngineered laminated bambooWorktops are similar in appearance to timber with a distinctive bamboo grain either horizontal or vertical. Available in light tan or honey colours. A fast growing, abundant and sustainable renewable resource. Bamboo worktops can be re-sanded throughout the lifetime. Bamboo is more durable and hardwearing than most types of hardwood. Easy to maintain and clean with a damp cloth/mop and a mild eco cleaning agent.
Metal worktops
Recycled stainless steel It is important to note that this material has a high level of embodied energy if virgin raw materials are used. Worktops can be made with up to 60% recycled steel content. Extremely durable with excellent hygienic properties. The standard worktop specified in commercial kitchens. Material is 100% recyclable. No adhesives required in fixing. Finish becomes scratched over time and material is prone to fingerprint marks non abrasive cloth and cleaning agent needed.
Recycled aluminium
* Some resins, sealants, adhesives, finishes and cleaning agents used with eco worktops contain solvents, plastics, chemicals and toxic additives check with the manufacturer. Search for non toxic, environmentally friendly, water based, formaldehyde free, solvent free and zero VOC substitutes. Remember an eco name doesnt always mean eco by nature beware of greenwashed products when planning your eco interior kitchen design.
