Local authority pilot project candidates sought
Recycled woodchip is becoming an increasingly popular choice for use as a plant bed mulch and paths and play area surfacing, but a new local authority study has revealed it could have far wider landscaping applications.
Research commissioned by WRAP (the Waste & Resources Action Programme) to explore all potential landscaping uses of the product in a local authority environment has now identified a variety of completely new and innovative uses, many of which provide additional benefits, such as marking picnic spots under trees, reducing erosion on steep banks and mopping up muddy areas around car parks or by the water‘‘s edge.
Conducted by researchers from the University College Northampton (UCN) SITA Centre for Sustainable Wastes Management at Redditch Borough Council in the West Midlands, the study showed these new uses equated to 16% (1,998m3) of the authority‘‘s total potential need for landscaping material (12,187m").
Traditional uses of recycled woodchip such as plant bed mulching, pathway surfacing and play area covering make up 61% (7,455m") of the potential requirement, but the research also identified 23% (2,734m") of ‘‘other‘‘ previously unidentified or less obvious opportunities for mulching and pathway surfacing.
Using recycled woodchip for these new and ‘‘other‘‘ applications also brings a variety of benefits. Areas that may previously have been unsuitable for public access become usable, maintenance is greatly reduced due to the product‘‘s effectiveness as a weed suppressant and its long lasting properties mean that topping up is only infrequently required. Using other traditional loose surfacing materials for these types of applications would almost certainly be too cost prohibitive whereas recycled woodchip can even offer savings in terms of whole life costs. Its versatility and long lasting properties also makes it ideal for use where shredded garden waste would not be suitable.
Julia Turner, Material Development Manager for wood at WRAP, said: "This study not only demonstrates to what extent local authorities can use recycled woodchip in traditional uses, but also how they can use the product in previously unconsidered areas. As well as helping local authorities meet their sustainability and environmental obligations, recycled woodchip – made from post consumer wood waste such as old pallets – is an extremely durable, cost effective surfacing product, which reduces maintenance requirements such as weeding and watering"

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
