Combustion and Environment - On-going R&D-projectsA short presentation of some of our on-going R&D-projects
Emission measurements in combustion plants – state-of-the-art 2014
National team leader IEA Bioenergy task 36 - Integrating energy recovery into solid waste management
Controlled composting with small carbon footprint
Mistra – Closing the Loop” – program host
The project involves a thorough update of Värmeforsk´s Measurement Handbook 2005 including new measurement technologies, new methods and standards as well as a survey of experiences made by users of the Handbook. This contributes to that emission measurements in combustion plants are conducted adequately resulting in correct results. This is an important prerequisite for optimal use of resources and low emissions.

IEA Bioenergy works to promote the use of clean sustainable energy at affordable prices in their member countries. More information on IEA bioenergy can be found at (www.ieabioenergy.org)
Task 36 is mainly working with different thermal treatment options (combustion, pyrolysis, gasification) for recovery of energy out of solid waste. SP participates as national representative for Sweden in this work. The aim is to bring forth Swedish interests into the work of the group as well as communicating the experiences from the other members to relevant stakeholders in Sweden.
Mainly the work is being done in association to the two workshops/meetings that are arranged each year. For more information about the Swedish work, please visit www.task36.se. (in Swedish only)
The project is funded by the Swedish Energy Agency

Horse manure is a major problem in Sweden. There is a need for more recipients of horse manure that can further refine it into an attractive soil improver. Today, it happens that horse manure is dumped out in the nature, which can lead to pollution (leaching of nutrients to water) or it is stored untreated with leakage of nutrients, which also has a major negative impact on the environment.
Unfortunately, considerable amounts of ammonia (NH3) and nitrous oxide (N2O) are released during composting. This means not only a loss of valuable plant nutrients but also a burden on the environment. Nitrous oxide, for example, is a strong greenhouse gas. Composting of organic matter releases heat that is not used with today's composting technology. Instead, the heat is vented away.
In Sweden, there are currently a number of drum composting plants for the treatment of animal manure. In these facilities, it is possible to control the composting process in a completely different way than in e.g. open windrow composting. But the drum composting process has not yet been optimized from an environment perspective, which first requires knowledge of the emissions levels of nitrous oxide and ammonia.
In this project, JTI and SP examine whether emissions from drum composting can be limited by controlling the process and how the emissions from post-composting are affected. Furthermore, it is to be examined whether the large amount of heat released during composting can be utilized in an efficient manner.
The project, which is a joint project between JTI and SP, is expected to be of great importance for "Horse Sweden".

Controlled composting with small carbon footprint
The " Mistra - Closing the Loop " program consists of seven individual research project :
1. Realizing Resource Efficient Recycling of Vehicles - Realize
2. Closing the Loop for phosphorous in chemical industry residues
3. Material Efficiency Management in Manufacturing - MEMIMAN
4. Sustainable recycling of " Green " plastics and industrial plastic waste
5. From Industrial Waste to Product Design
6. Increased use of by- products and wastes from the steel industry in cement production
7. Quick Flux - Production of calcium aluminate out of aluminum black dross
Research and development for over 50 million SEK will be carried out under the program for three years.
SP as the program host has the task of coordinating the individual projects to allow for synergy effects and to simplify internal and external communication of the projects and the program.
Program host role includes also working on synthesis between the projects and writing synthesis report . The purpose of these activities is to create added value to the program through the integrated analysis of knowledge gained by individual projects. Synthesis report aims to describe the results of the entire program. In this report , the results will also be presented and analyzed in a larger context than it has done in the individual projects.
