tailieunhanh - METSO’S CUSTOMER MAGAZINE FOR THE PULP AND PAPER INDUSTRY

Pulp and paper is a mature industry. Industrialised paper manufacturing in Europe started in the early 19th century (Berkhout, 2005). It is a capital and resource-intensive industry that contributes to many environmental problems, including global warming, human tox- icity, eco-toxicity, photochemical oxidation, acidification, nutrification, and solid wastes (Blazejczak and Edler, 2000). Paper is made of natural fibres, either from wood or from recycled materials. Figure 1 below presents a schematic representation of the production system. The harvested wood is first processed so that the fibres are separated from the unusable fraction of the wood, the lignin. Pulp making can be done. | METSO S CUSTOMER MAGAZINE FOR THE PULP AND PAPER INDUSTRY No. 2 2010 SC A Packaging Munksund White liquor quality and capacity up thanks to cutting-edge technology 12 Mondi Swiecie ECO - Economy meets ecology 1 Metso and Tamfelt join together - A perfect union formed for the customers 8 Game-changing multilayer curtain coating technology - Are you ready 15 J A completely new and unique laboratory cooking system is being built in Karlstad. Several improvements are also being made at the pilot plant in Sundsvall. Read more on page 34. Dear reader Even though the global recession has slowed down business it has not put a brake on our efforts to develop new technology. Early in the year we kicked off a multi-year project together with Stora Enso and Domtar DMS to develop a pulp mill biorefinery of the future utilizing new pulp technology. We re aiming at a process with better energy and cost efficiency lower capital investment costs and a more economical use of fiber. We believe we can achieve all of these goals without compromising on the pulp properties required for excellent paper or board - in fact just the contrary The technology being developed will provide better opportunities to produce new wood-based biocompounds. The new DMS project will offer exciting new possibilities for a breakthrough in sustainable chemical pulp production. As such it accords with the strategic RTD objectives set for the Finnish Swedish and North American forest clusters. We are focusing another major effort on rebuilding the pilot paper machines at our Jyvaskyla Paper Technology Center. Now we will be able to provide even more flexibly than before pilot trial possibilities that are at the cutting edge of global development - including ground-breaking paper making technology that will afford our customers superb opportunities to stand out from their competitors. Our PM 2 the first pilot machine to be rebuilt now adds a new gap former to its previous former that allows the production of .
