Purpose and objectives<\/h3>\n

The purpose is to enable Swedish municipal utilities to transform sludge from a disposal problem into a configurable resource hub supporting resilient, low-impact water services. Modular sludge disintegration configurations will be tested using pilots and full-scale data to quantify effects on biogas production, internal carbon supply, nutrient recovery, micropollutants, dewatering and greenhouse gas emissions. Based on this, plant-wide models, business cases and implementation guidance will be developed to reduce investment risks and provide practical decision support for utilities of different sizes and conditions.<\/p>\n

Expected impacts and outcomes<\/h3>\n

By 2028, system-integrated sludge disintegration concepts will have been tested and documented with quantified impacts\/potential on biogas yields, internal carbon supply, nutrient recovery, micropollutant, dewatering and greenhouse gas emissions. The project will deliver plant-wide models, business cases and implementation guidance. This is expected to increase energy self-sufficiency, reduce fossil chemical use, decrease sludge volumes and transport, clearer pathways for safe nutrient products and improved PFAS and pharmaceutical control. Together, these effects strengthen the resilience of wastewater services and support wiser use of resources in the urban water cycle while reducing pollutant loads to the environment.<\/p>\n

Planned approach and implementation<\/h3>\n

The project combines technical testing, system analysis and implementation support. Partner utilities and researchers will first map sludge lines, needs and constraints and design modular disintegration configurations. K\u00e4ppalaf\u00f6rbundet will install and operate a near full-scale pilot, while process effects, resource recovery and micropollutant behaviour are characterised using this pilot, V\u00e4xj\u00f6\u2019s thermal hydrolysis line and data from Syvab and other plants. M\u00e4lardalen University and IVL will develop calibrated plant-wide models and business cases quantifying climate and cost impacts. In collaboration with Ramboll, Svenskt Vatten and the nutrient platform, the project will also develop governance approaches, procurement templates and stakeholder dialogue to prepare utilities for stepwise full-scale implementation.<\/p>\n
