Abstract: The invention relates to an apparatus for producing a pyrolysis product, the apparatus comprising a pyrolysis reactor for forming pyrolysis product fractions from raw material by fast pyrolysis, a condensing device for condensing gaseous pyrolysis product fractions to mainly liquid pyrolysis product fractions, a combustion boiler arranged in conjunction with the pyrolysis reactor for forming energy fractions, and feeding devices for feeding raw materials to the pyrolysis reactor and the combustion boiler. According to the invention, the apparatus comprises a separating device arranged substantially in conjunction with the pyrolysis reactor for separating other fractions from the gaseous pyrolysis product fractions after the pyrolysis and means for conducting other fractions than the gaseous pyrolysis product fractions from the separator to the combustion boiler.

Abstract: The invention relates to a method for carrying out pyrolysis in such manner that a first raw material is fed to a combustion boiler and a second raw material is fed to a pyrolysis reactor which are integrated together, energy fractions are formed from the raw material in the combustion boiler and gaseous and liquid product fractions are formed from the raw material in the pyrolysis reactor by fast pyrolysis.

Abstract: Method and apparatus for producing fibre pulp and fuel out of municipal waste or for producing fibre pulp out of waste paper. To control the microbe content, the retention time of the process is kept shorter than 12 hours, advantageously shorter than 6 hours. This is achieved by minimizing the total liquid volume of the process and by increasing the amount of water being passed to water treatment from the process, which water, having been purified, is possibly returned to the process. The method may also include a phase in which the pulp is treated thermally in order to destroy the microbes present in it.

Abstract: The invention relates to a method for processing waste, in particular for utilising the recyclable material contained in waste, and a waste processing plant, in particular a plant processing waste fractions suitable for recycling of material. At first, the waste is pre-treated for removing undesirable matter. Fibre waste is separated from the other waste and processed into a raw material for paper or board. Plastics-containing matter is separated and processed into plastic oil by pyrolysis. The by-products from the processes and the waste fraction which remains of the processing are used as energy for the needs of the processes. The method can additionally comprise a stage in which waste wood is separated from the other waste and processed into a raw material for particleboard or equivalent.

Abstract: Raw material, energy and waste management are arranged in a production plant manufacturing pulp, paper, or board or a combination thereof from recycled fibres which is advantageously placed in the middle of a residential community or in its immediate vicinity. The plant has equipment for the manufacture of pulp and/or paper and/or board as well as equipment for the production of energy for at least the production plant's own needs. The production plant uses as fibre raw material waste paper and/or board generated by the residential community and as the source of energy combustible waste generated by the residential community. Moreover, it utilizes as far as possible waste fractions which are produced as by-products in production processes and which contain raw materials and energy either as raw material or as energy or, alternatively, these fractions are supplied outside the production plant for useful use.
