Biochar – The Next Standard in the Circular Economy
Biochar is a powerful tool for solving problems in challenging operational environments: it can be used to improve the properties of soil for better growth, cleanse polluted soils and filter contaminated ground water. It is also a robust tool to fight climate change, as it also decreases carbon dioxide emissions. It is truly regenerative, as it often uses waste materials to achieve savings in emissions and soil and water improvements.
The illustration demonstrates the various benefits of using biochar in seedbeds in urban environments.
Finnish Biochar to Swedish Cities
Noireco is on a quest to promote carbon neutrality not only in Finland but also abroad. We have delivered biochar to Sweden since 2013. Stockholm is a pioneer in utilizing biochar for urban planting, for example, street planting. However, we have supplied biochar to other cities as well, such as Malmö, Norrtälje and Eskilstuna. The amounts of biochar have been remarkable; over the years, more than 100 full truckloads have reached their destinations in Sweden. Biochar production occurs in Sweden too. For example, in Stockholm, the garden waste that is collected from city residents is used as raw material for preparing biochar.
It is worth noting that instead of complete seedbeds, we have delivered plain biochar to our Swedish customers. Using our high-quality biochar base, they have composed the desired growth media mix according to their needs. Noireco has proven itself as a loyal business partner as we can guarantee reliability in delivering large amounts of biochar on time.
1 kg of biochar reduces 3,5 kg of CO2 emissions.
Biochar in Concrete Jungles
Urban environments create challenging living conditions for plants. Tarmacked roads, pavements and curbs restrict the space that plants and roots need for growing. Urban structures also make it more difficult for plants to get water and oxygen. This results in weaker and slower growth, or the plants may even perish due to the harsh conditions. Roots try to reach for more room for growth, which may damage street infrastructure.
A Black Sponge
The use of biochar improves the living conditions of plants in cities. Biochar has a porous structure, which brings about several positive effects when biochar is applied to soil. If biochar is added to seedbeds, it improves aeration in the soil. Pores in the biochar structure can absorb water and nutrients, retaining them and making them available to plants when needed. Biochar pores also provide good growing conditions to microbial and mycorrhizal populations living in the soil.
Recycling Waste Water
Plants grow healthier and live longer with biochar application, saving money and resources required for taking care of urban street planting. Additionally, these street plantings can be designed to help with urban stormwater management. Biochar is an extremely absorptive material, and it can absorb and retain water multiple times its own weight. Biochar-based seedbeds reduce the stress on drainage systems caused by melting snow and ice or storm downpours. Instead of draining stormwater into the drainage network as sewage, biochar makes it possible to utilize and conserve natural water for irrigation.
Stockholm is on track to becoming a Carbon Neutral City. Biochar is a crucial part of this journey.
Our team at Noireco would be happy to help other cities to take their first steps in the same direction.
