Paper Without Waste: Circular Loops in the Lucca Paper District
Entity: Lucca
Country: IT
Website: https://www.retecartesio.it
The Lucca paper district, one of Europe’s largest paper production areas, has implemented an industrial symbiosis strategy that connects pulp mills, recycling plants, and energy companies into a circular system. By exchanging waste, energy, and secondary materials, the district has reduced environmental impacts while improving efficiency and competitiveness across the paper industry.
Paper production in Lucca generates large amounts of sludge and requires high energy inputs. Rising disposal and energy costs made traditional linear practices increasingly unsustainable, pushing companies to collaborate on shared circular solutions.
A central element of the district’s approach is sludge recovery. More than 90 percent of paper sludge is processed into solid recovered fuel or compost, significantly reducing landfill disposal and turning waste into a usable resource. Energy sharing is another key component: heat and power produced from waste incineration are shared among paper mills, lowering energy costs and reducing the overall carbon footprint.
Digital coordination supports these exchanges. Lucense developed a resource mapping and monitoring platform that tracks material and energy flows within the district. In parallel, the Cartesio Network provides training for employees and entrepreneurs on industrial symbiosis and circular economy practices, strengthening skills and awareness across the sector.
The results include major reductions in landfill use, lower energy costs, and the creation of new roles in environmental services. The Lucca model has proven replicable and has been applied in other paper districts in Italy and Europe.
Key lessons from the Lucca paper district show that sector-wide cooperation increases material efficiency, digital monitoring supports resilience, knowledge-sharing strengthens innovation, and circular practices can improve both reputation and long-term investment potential.
