Circular economy in briefFrom linear to circular chains

A circular economy aims to keep products, components and materials in a continuing cycle instead of disposal.

Waste is minimized or eliminated for example through using side streams in other applications, processes or even industries.

Circular economy creates new business potential across industries through more efficient use of material flows.

Resource efficiencyRefers to the efficient use of resources, so that the amount of recources (materials, energy, water, chemicals) needed to produce the products can be reduced.

Closed cyclesRefers to material flows within one production unit/organization/industry aiming at creating closed loop systems with no waste.

Longer circulationRefers to cycles where materials last longer, e.g. their lifecycles are extended, through e.g. more efficient recycling.

Cascaded use across industriesRefers to material flows cascading from one value chain/industry to another e.g. by using sidestreams from one value chain/industry as inputs into another industry.

Main circular economy themes from customers’ point-of-viewResource efficiency Improvement and optimization

of resource efficiency Flexible energy production

Closed circles Chemical and energy recovery

Longer circulation Design enabling reuse and conversion Maintenance and modernization of production technology

Cascaded use across industries New bio-based products

1. Improvement and optimization of resource efficiency

Concrete examples: Significant savings in energy, water and raw

materials in paper making technologies e.g. OptiConcept M paper and board machines, Advantage DCT and Advantage NTT tissue machines

Measurement solutions and industrial internet enable data analytics to detect production inefficiencies and optimize material use

Performance agreements provide a comprehensive approach to improve mill wide production efficiency


Resource efficiency can be improved through technology, automation and maintenance

2. Flexible energy production

Concrete examples: Waste-to-energy solutions by fluidized bed boiler

and gasification technologies enable efficient energy recovery

Fuel flexibility with multi-fuel boilers, which can operate on fuel mixtures ranging from 100 % coal to 100% biomass

Wider use of fuel sources by fluidized bed boilers, which can utilize fuels with varying energy value and moisture content


Valmet’s energy production technologies reduce the need for non-renewable fuels and the amount of waste

3. Chemical and energy recovery

Concrete examples: Recovery island enables efficient recovery of

chemicals and energy in a pulp mill

Sulphur recovery from odorous gases enables on-site production of sulphuric acid

Internal recovery and recycling solutions in production processes e.g. condensate water recycling and paper pigments recovery


On-site recovery of energy and chemicals allows materials to circulate longer and reduces the need for virgin materials

4. Design enabling reuse and conversion

Concrete examples: Paper machines can be converted to produce

board or other paper grades

Modular design of machines and plants make it possible to replace individual machine parts

Machines can be dissembled and reassembled in another location

Flexible design enables changes based on market needs (e.g. Advantage NTT, multi-fuel boilers)

Modular I/O-cards(* enable system updates without the need to update the core system


Modular design and smart engineering enable the use of same equipment for other uses

*) I/O-cards = input / output cards

5. Maintenance and modernization of productiontechnology

Concrete examples: Preventive maintenance can be planned utilizing

big data analytics e.g. in roll maintenance

Refiner segments, rolls and certain wear parts are refurbished and used again and again

Individual process parts or complete mills and power plants can be modernized to extend the life time

Boilers can be modified to use another fuel e.g. from coal to biomass


Equipment lifetime can be significantly prolonged with well planned maintenance and partial replacements

6. New bio-based products

Concrete examples: LignoBoost technology makes it possible to extract

lignin from pulping process side stream, and lignin can be used as raw material for bio-based materials and chemicals

Technologies for bioethanol, biocoal and bio-oil production help to replace non-renewable fuels and materials


Solutions for new bio-based products decrease the need for non-renewable materials

Valmet’s own operations

Concrete examples: Energy audits, quality and environmental

standards, and LEAN principles are applied to improve efficiency of production operations

Majority of metals sourced is recycled and internally reused e.g. in foundries

Resource efficiency and good environmental management are required from suppliers

Laboratory and piloting facilities are shared with customers

Preventive maintenance prolongs the life time of production equipment


Efficient use of metals and other raw materials in own production and supply chain
