Sustainable management of public forests in Catalonia using a Wood-Mizer saw

The MMBB project, which has been joined by many urban communities in the Catalonia region, is successfully developing a circular economy for the efficient and waste-free use of wood from public forests.

MMBB (Mancomunidad de Municipis Bergedans per le Biomassa - Association of Berguedane Municipalities for Biomass) is a project developed by 8 municipal councils and the Ministry of Agriculture of the Government of Catalonia. The project is a good example of cooperation between towns of different sizes (for example, Berg has 17,000 inhabitants, while Gisclareni has only 30). "The aim of the MMBB project is the sustainable management of our public forests"says Moisés Masanas López, mayor of Saldes.

Sustainable forest management in Catalonia 

The project started in 2012, when 7 municipal councils signed the first agreement, then the Ministry of Agriculture joined the initiative and at the end of 2019, another local council in Solsonès also joined the MMBB. 

"We are developing several projects"says Moisés Masanas. "First, we decided to create a market for wood shavings for 14 thermal power plants supplying 32 targets in our area. This project allows us to use wood waste that would otherwise have zero value.". 

The first step was the construction of thermal power plants, including a boiler to provide heat for the industrial area in Berg. 

"Subsequently, we started a project to increase the added value of wood. We feel that if we have a product to manage, and the product has a low market value, it hurts us. Therefore, we have to make sure that the value of the product is increasing. In addition, we have quality wood that we don't want to use to generate cheap products. With the Wood-Mizer saw, we solve this problem and bring a new, higher value product to the market."

"We installed the Wood-Mizer saw in Saldes," says Lluis Campmajò Puig, mayor of Gósol. "We cut logs, and for those who need it, we have lumber, planks, beams, wood good for everything from furniture to roofs, from beams to renovating the whole house."

"The saw works great"says Lluis Campmajò. "We need to use this to add value to our wood. We are considering building wooden houses in our region, a finished product. We will use wood from our forests, cut it, dry it and build houses." 

"We source the highest quality logs from the forest and produce planks of various sizes for carpentry or urban projects that need wood"says Anna Jordà, Wood-Mizer saw operator at MMBB. 

Quality wood from the forests of Catalonia

"With the Wood-Mizer LT40 saw, we produce planks of the required thickness. Then another machine, the Wood-Mizer EG300 circular saw, cuts them to width and then to length. That way we get products of the right dimensions." 

The Wood-Mizer LT40 is operated remotely via the control station, where the operator controls all parameters. Here the operator sets the required thickness of the plank and then the saw head is automatically positioned in the right place. 

MMBB produces planks in standard sizes: 27 x 155 millimetres wide; the length depends on the length of the cut log. It currently cuts six or seven logs a day. 

"The LT40 saw is quite easy to use," says Anna Jordà, "Once you start the saw and make a few cuts, you see how it works, you understand everything and it becomes easy. It doesn't take much effort because the machine does almost everything itself. The LT40 saw picks up the logs from the ground, loads them onto the bed, cuts it, and finally clears the planks to be stacked." 

"The LT40 saw is very reliable and safe to use. The saw head moves, but the operator does not walk behind it. It is controlled from a remote panel; there is no danger while working. And changing the ribbon blade is also easy. The machine requires no difficult maintenance. You just have to remove the sawdust from the cutting area and you can continue working."

Developing a circular economy 

MMBB aims to develop a circular economy and create jobs in the participating villages. 

"We are not worried about depopulation because we are already affected by it. But we can do something important to repopulate these mountain villages. We need real, full-time jobs, not just seasonal ones." 

Many people from this region already work for MMBB. There are 34 people on staff and six more auxiliary staff. 

Another idea is to improve the management of the heating plant. "Now we sell thermal kilowatts, but we have fluctuations in consumption. We produce electrical kilowatts, primarily for our villages, and then we sell to the grid, and that will make us more flexible in our management." 

Project participants would not achieve these results if each municipality worked alone, auctioning only its own timber. And the number of workers would be smaller because of the seasonal nature. Now they make more profit based on economies of scale, adding value to the product and being more efficient. 

"We must continue to improve where we are not yet efficient enough and continue to create much needed jobs."
