8 8 CELBI FROM WOOD TO PULP Wood debarking chipping wood cooking Celbi produces paper pulp using exclusively eucalyptus wood. The wood arrives at the mills in the form of logs with bark. The wood is debarked and converted into chips which are gathered in piles. After a screening process, the chips are fed into a continuous digester together with white liquor (cooking chemicals). The chemicals dissolve the lignin, the substance responsible for binding the cellulose fibres together, releasing them and thus resulting in the so-called unbleached pulp. oxygen, hydrogen peroxide and chlorine dioxide. By the end of this phase, the pulp looks like a white thick suspension. The bleached pulp suspension is then subjected to a final screening and depuration before being put on a double running wire system to form sheets, where most of the water is taken away, first by pressing and then by vacuum drying. The unbleached pulp is then washed to remove residual products, organic and inorganic, which result from the cooking process and is then submitted to screening operations that will remove uncooked particles and other impurities. The pulp is then pressed and dried by a compact drying system with heated air. After being dried, the final sheet is cut into smaller sheets which are stacked into bales of 250 kg and then carried to the pulp warehouse. After these operations, the unbleached pulp is submitted to an additional delignification with oxygen, out of which results a semi bleached pulp a yellowish pulp that is sent to the bleaching facility. In the pulp warehouse, the bales are grouped and wired into units of eight bales. They are stacked and later loaded onto lorries that transport them to the trading port or directly to the client. When entering the bleaching plant, the pulp still contains residual compounds as a result of the degradation of lignin, which are gradually removed through chemical reactions with bleaching agents such as The diluted black liquor discharged from the digester, resulting from the cooking of wood chips and in a diluted form, is concentrated until a thick biofuel is achieved. This concentrated black liquor is then burnt

9 CELBI ENVIRONMENTAL STATEMENT pulp washing pulp bleaching pulp drying pulp bales chemical recovery and energy production in the recovery boiler. The inorganic chemicals of the black liquor form a substance which, after being dissolved in water, forms green liquor, consisting of a large fraction of sodium carbonate and sodium sulphide. In the causticising process, lime is added to the green liquor, thus originating white liquor (sodium hydroxide and sodium sulphide) and calcium carbonate. This, in suspension, is removed and dried and then again converted into unslaked lime in the lime kiln. Closing a cycle, the regenerated white liquor in the causticising process will again be used in the cooking process. WATER SUPPLY The raw water has two different origins: underground water from wells and surface water from the Mondego River. The treatment consists mainly of a flocculation process followed by sedimentation and filtration through sand filters. ENERGY SUPPLY The energy used in the pulp manufacturing process results from the burning of the concentrated black liquor in the recovery boiler and, when necessary, from the burning of natural gas on an auxiliary boiler. The high-pressure steam produced in the boiler is expanded in a backpressure turbogenerator with 75.9 MVA of equivalent electric power and in a balance condenser with 6.5 MW of power, which is subsequently used in the process at medium pressure or low pressure. The energy released through expansion in the steam turbine is converted into electrical energy which, on average and in normal operation conditions, meets the needs of the mill. The mill s internal medium voltage electricity distribution system is permanently connected in parallel with the national network, enabling energy exchanges (buying and selling) between the systems. Celbi s thermoelectrical station, which includes the recovery boiler and the turbogenerator, is licensed as a co-generator and uses primarily biomass as fuel.

10 10 CELBI RESIDUAL WATER TREATMENT There are three separate networks of internal effluents: one for acid effluent, another for alkaline effluent and a third one for domestic effluent, effluent from the wood yard and rain water. The effluents originated from these two sedimentation ponds are mixed in a chamber and sent to the secondary treatment unit. The final effluent is discharged in the Atlantic Ocean, 1.5 km off the shore, through a submarine pipeline equipped with a diffuser. All effluents go through a primary treatment process for removal of suspended solids in two separate sedimentation ponds. Part of the waste from the primary treatment containing fibres is sold as raw material for paper and cardboard production. This biological treatment unit for Celbi s liquid effluents completes the primary treatment described. INDUSTRIAL EFFLUENTS Acid Álcali Nutrients SEDIMENTATION (primary treatment) NEUTRALISATION EQUALISATION POND COOLING TOWERS Residues from primary treatment

11 CELBI ENVIRONMENTAL STATEMENT This treatment process includes the following steps: neutralisation, equalisation, cooling, aerobic treatment (activated sludge) and final clarification. The sludge resulting from the process, after being mixed with primary sludge and dehydration, is sent to the waste composting plant or it is used for other valorisation processes. GASEOUS EMISSIONS TREATMENT The gases resulting from the burning of black liquor in the recovery boiler are treated in electrostatic precipitators for removal of particles before being discharged through the stack. The gaseous emissions (particles, SO 2, TRS, CO and NOx) are continuously monitored by online instruments. The gases from the lime kiln go through electrostatic precipitators for removal of particles being discharged through the stack. The gaseous emissions (particles, CO, NOx, SO 2 and TRS) are continuously monitored by online instruments. AEROBIC BIOLOGICAL REACTOR (secondary treatment) CLARIFIER TREATED EFFLUENT The residual gases originating from the washing, screening, bleaching and chlorine dioxide production plants are collected and washed with an alkaline solution in a gas scrubber before being sent into the atmosphere through the stack. The condensates resulting from the evaporation of the black liquor undergo a purification process in a stripper, generating methanol and non-condensable gases that are later incinerated in the recovery boiler, thereby creating energy value. WASTE MANAGEMENT AND BIOMASS Air Residues from secondary treatment Part of the non-hazardous industrial waste from the process activities is deposited in the waste controlled landfill (WCL) of the mill which has been in operation since The organic waste resulting from the wood preparation as well as the sludge from the effluent treatment is processed in the waste composting plant. The waste resulting from non-process activities (paper, plastic, glass, used oils, waste contaminated with oils, metal, etc.) is collected through an extensive network of containers for selective collection and sent out to external authorised waste management operators for treatment, elimination or further uses. The bark and residual biomass from the wood yard and wood preparation plant resulting from the debarking of wood for the process are sent to the Biomass Power Plant (EDP Produção Bioeléctrica S.A.) in order to generate electricity.

12 12 ÍNDICE CELBI S ENVIRONMENTAL MANAGEMENT SYSTEM

13 CELBI ENVIRONMENTAL STATEMENT Celbi s Environmental Management System is structured in compliance with the ISO Standard and with the Regulation of the Community System of Eco-Management and Audit Scheme (EMAS) of the European Union. The company has been certified according to the ISO Standard since 1999 and has been registered in EMAS since In March 2012 Celbi also obtained the certification of its Energy Management System in conformity with the ISO Standard. ENVIRONMENTAL MANAGEMENT SYSTEM ISO ENERGY MANAGEMENT SYSTEM ISO QUALITY MANAGEMENT SYSTEM ISO 9001 OCCUPATIONAL HEALTH AND SAFETY MANAGEMENT SYSTEM OHSAS CHAIN OF CUSTODY FSC CHAIN OF CUSTODY PEFC ACCREDITADED LABORATORY ISO The Environmental Management System clearly regulates how the legal requests should be identified and dealt with. Potential risks for the workforce, facilities and the environment are identified and the correspondent mitigation/control measures are stated. An Internal Emergency Plan has been produced showing the possible emergency scenarios and the correspondent procedures for preventing and/or avoiding their consequences were set up. All contractors operating within the mill site are subjected to the Management System procedures, particularly to those concerning environmental and occupational health and safety issues. The documents composing the Environmental Management System are organised according to the following hierarchy: Sustainability Policy; Environmental Management Manual; Environmental issues and their corresponding impacts and control measures; Objectives and Specific Development Programmes; Procedures; Emergency Plans; Records. EMPLOYEES PARTICIPATION The production and editing of the documents concerning the environmental aspects are made with the close participation of the employees working at those areas or activities. Employees also take part in the work groups set up for continuous improvement (Specific Development Programmes, reliability groups and Kaizen meetings), in the Environmental, Health and Safety Commission and in periodic meetings involving various levels of the organisation. All the information concerning the company s environmental performance is available on the Intranet, which is accessible to all levels of the organisation.

14 14 ÍNDICE SIGNIFICANT ENVIRONMENTAL IMPACTS

15 CELBI ENVIRONMENTAL STATEMENT MODEL FOR ASSESSMENT OF ENVIRONMENTAL IMPACTS The Register of Environmental Aspects describes the way that Celbi activities affect the environment. This register illustrates the environmental impacts associated with the various facilities and categorise them bearing in mind three operational conditions. OPERATIONAL CONDITIONS SITUATION DEFINITION/CONDITIONS NORMAL OPERATION Operation running smoothly, under control, within typical and usual conditions and according to plan. SHUT-DOWN/START-UP Somehow unstable conditions, such as those prior to or following an operational disruption that has been planned and is under control, either of short or long duration. INCIDENT Unexpected and uncharacteristic occurrence such as a breakdown, failure, leakage, explosion, etc., that may require corrective measures or cause shut-down due to failure of immediate control. Environmental impacts are assessed on three levels, as shown in the following table: ENVIRONMENTAL IMPACT ASSESSMENT SCALE OF IMPACT DEFINITION MINIMUM/MARGINAL 1 Small scale impact with consequences and emissions within legal limits, international recommendations and within the capacities of the receiving media. MEDIUM/MODERATE 2 Medium scale impact, moderately tolerated by the environment, locally or globally, such as those caused by incidents or disturbances that may lead to a temporary increase of environmental parameters. SERIOUS/MAJOR 3 Impact bound to cause severe damage to the environment, locally or globally, or impact that originates from and causes emissions above the legal limits. Assessments are carried out periodically with the employees participation and closely follow the procedures stated in the Environmental Management System.

16 16 SIGNIFICANT ENVIRONMENTAL IMPACTS The following table summarises the most significant environmental aspects (scale of impact 3), identifies them as direct or indirect and shows the measures to control and/or reduce the risks, including the environmental objectives and the associated environmental targets.

34 34 ÍNDICE ENVIRONMENTAL OBJECTIVES AND PROGRAMMES

35 CELBI ENVIRONMENTAL STATEMENT Objective To reduce the specific water consumption to the following values: 2018: 15 m 3 ptp Start: December 2012 Timeframe: End of 2018 CEAG PROGRAMME The specific use of water in 2017 was 19.4 m 3 / tpsa. A new Working Group was set up to follow up this programme, by holding regular meetings and registering ongoing measures, and sectoral consumption was studied with a view to setting targets. As for Project C17, conditions were created for better water recovery in the Pulping Group (digester, washing and sieving and bleaching), and some reduction actions were implemented after the annual stoppage in The months of November and December showed the results of these actions, with the best results for the year, respectively 17.8 and 16.9 m 3 / tpsa. Objective Elimination of the wood yard waste sent to the Waste Composting Plant (WCP) by reusing it in the process. Start: October 2014 Timeframe: End of 2017 RESCOM PROGRAMME The annual amount of waste processed at the WCP in 2017 has reached the levels recorded in 2014, despite the increase in pulp production at the mill. This increase in the shipment of waste from the wood yard to the WCP was mainly due to the fact that there is no economically viable solution for biological sludge yet as an alternative to being sent for composting. Waste from the timber yard occupies the largest slice of waste shipped to the WCP, since the composting process works poorly without this type of waste. Therefore, its use in the WCP is maintained. Another improvement programme was launched in 2017 with the objective of making the energetic recovery of biological sludge in the Recovery Boiler possible, and this is expected to enable the complete elimination of waste disposal for composting. It was decided to close this Programme. CLOSED

36 36 ENVIRONMENTAL OBJECTIVES AND PROGRAMMES Objective Program C17 has defined the following objectives: Increased energy efficiency Reduction of the environmental impact Reduction of the consumption of bleaching chemicals Increased process stability Increased reliability of manufacturing facilities Start: February 2016 Timeframe: June 2018 PROGRAMME PROJECT C17 This project does not foresee changes in the current infrastructures (highways, buildings, streets) just the replacement of some procedural equipment. Two areas of the manufacturing process will be intervened: Installation of a new line of debarking and dewatering of wood with a capacity of 510 m 3 sob / h. Installation of new washing equipment which should increase the efficiency of the installation, reducing the consumption of bleaching chemicals and the organic load of the final effluent. The estimated value of this investment is of EUR 40 million, aiming at maintaining an ecologically balanced factory, in compliance with the national and Community legislation, as well as having full awareness of the Best Available Techniques (BAT) applicable to the paper and pulp production sector. As regards its installation, the C17 project is considered to be completed. As agreed with the suppliers, the performance tests will be held as soon as deemed appropriate by both parties. They were preliminary scheduled for the end of the first quarter of The timeframe for the closure of the Programme was redefined for the end of June 2018

37 CELBI ENVIRONMENTAL STATEMENT Objective To eliminate biological sludge for composting through the energy recovery of biological sludge. Start: January 2017 Timeframe: End of 2019 VALAMAS PROGRAM CELBI has gradually increased its pulp production and along with this increase there has also been an increase in the production of biological sludge in the secondary effluent treatment. The extremely high values of biological sludge production require technically and economically viable alternatives for their recovery inside or outside CELBI s facilities, as long as they are environmentally appropriate. For a number of years, priority has been given to the development of biological sludge in preparation of a compound for agricultural and forestry application. For this purpose, a composting unit for biological sludge and other waste was installed in CELBI. However, year-over-year, it has become increasingly difficult to ship the compound obtained in the composting operation for agricultural or forestry recovery; in addition, there are problems associated with the odors resulting from the fermentation of biological sludge at CELBI, situations which will certainly worsen in the coming years. Thus, in the context of the request for renewal of the CELBI Environmental License, as an alternative to composting, the Portuguese Environment Agency (APA) was requested to authorize the energy recovery of the biological sludge in the Recovery Boiler. In October 2017, APA granted the first amendment to the CELBI Environmental License in which the code LER was included (Sludges from local effluent treatment, other than those mentioned in primary sludge, secondary sludge from biological treatment) in non-hazardous waste acceptable for energy recovery in the Recovery Boiler. This project is under study. Objective Check the need for an update of the REACH registration dossiers and of the white and green liquor safety data sheets based on their sulphide concentrations. Start: October 2017 Timeframe: End of 2018 REACH PROGRAM In accordance with the Regulation (EC) No 1907/2006, CELBI had to register the substances it produces internally with the ECHA (European Chemicals Agency). This registration was carried out by submitting a technical dossier, the content of which is described in Article 10 of the Regulation. ECHA has recently requested to consider the concentration in sulphide of the white and green liquors instead of the product in solution when registering. In this sense, CELBI will have to determine the sulphide concentration of its liquors and proceed to an update of the dossiers accordingly. A proposal for training covering REACH and updating of dossiers was requested. After this training, an audit of the dossiers is planned so as to identify the need for an update of the current level of compliance with REACH.
