Ultra Low dust: small-scale biomass combustion technologies with ultra-low emissions

An ensemble of three innovative technologies covering the whole range of residential biomass heating appliances defines a new State of the art regarding ultra-low emission biomass combusting systems. These technologies are: ultra-low emission pellet and woodchip boilers; new stove technology based on optimised air staging and on automated control system; new electrostatic precipitator system (ESP) for old stoves and boilers.


In recent years, the quantity of Solid Waste collecting has increased significantly in the EU and other industrialized countries. The problem of managing waste strongly affects not only the environment protection but also resource savings. The storing of waste tyres represents a problem within the waste management strategy of the European Community: the world production amounts to 7 million tons (according to the European Tyre Recycling Association, Report 2008), of which 3 million are generated in Europe which corresponds to 2% of the total solid waste production. Even today the final destination of nearly 23% of such an amount is the landfill, with the consequent loss of high added value materials and the adverse environmental impact.


Aerosols are minute particles suspended in the atmosphere which have a strong influence on air quality, since they scatter and absorb solar radiation, changing the Earth radiation balance and consequently global temperature patterns. Additionally, as they act as cloud condensation nuclei, they are also influencing precipitation trends.


The aim of NATAIR is to improve the accuracy of the data analysing and calculation methods from natural and biogenic emissions and to assess their impact on air pollutant concentration levels and deposition loads in Europe. The projects has developed datasets for modelling on concentration levels from anthropogenic (e.g. combustion processes) and natural (and biogenic) sources.


Bitumen is a petroleum-based material used in many applications within the construction sector. The material can for instance be applied as a binding agent in roads or as roofing materials for flat roofs. Despite the present awareness in the use of natural resources, especially of fossil origin, bitumen is not widely recycled yet. In many countries a more common method of getting rid of the material is incineration or landfilling, mostly due to a lack of alternative damage-reducing techniques


The technology that has been developed within the CAPS project (funded under CIP programme, a grant funding programme) should allow the paper industry to value its waste, particularly in the field of paper mill sludge disposal and recovering. The increasing demand for a more sustainable absorbent and for an appropriate treatment of papermill sludge within papermills, has led the project’s partners to develop an innovative physical separating process in order to convert the paper mill sludge into an efficient absorbent material.
