Waste-​Polymer Enhanced Asphalt

ReSource International ehf. have been working hard at experimenting with waste-​polymer enhanced asphalt. The project has been funded by Tækniþróunarsjóður Rannís and the results are strikingly good.

The research objective is coined in order to ensure an economically feasible, residual resource-​reliant and environmentally friendly solution for bound asphalt which simultaneously enhances asphalt and supports Iceland’s goals on sustainability.

Main results: 28 asphalt mixtures were tested, four replicates for each asphalt mixture, which were tested for: Marshall stability and flow, density and void content.

The results indicate that a doubled force is needed to break asphalt enhanced with waste-​polymers. Lastly, wheel-​track tests were performed which shows the tendency of asphalt to form wheel-​tracks.

Wheel-​track results show that the addition of waste-​polymer decreases the asphalt‘s tendency to form wheel-​tracks. Waste-​polymer enhanced asphalt has set a record for the lowest wheel-​track formation recorded by the Icelandic Innovation Center (NMÍ) for the last 10 years (at least).

Next steps: To contionue, this project ReSource is going to send asphalt samples to test the resistance of spiked tires and monitor the particulate matter for microplastics. Additionally, there are plans to lay a test section of waste-​polymer enhanced road in order to monitor the performance of the asphalt in a real-​life situation.

ReSource is looking forward to developing the project further and is excited to see the impact it will have on plastic recycling in Iceland.


Operation of Gas Collection System at the Landfill Site in Glerárdalur

Since its beginning, ReSource International has been working on developing new approaches and methods for landfill gas collection management. We help our customers in their daily operation in order to optimize the gas collection and reduce greenhouse gas emissions. Today we start our field work with Norðurorka which produces biofuel from the old landfill of the town in the North of Iceland. Methane gas is being utilized and supports Norðurorka’s environmental policy in reducing greenhouse gas emissions and utilizing renewable energy resources.

New Method Developed for Microplastic Measurement in Drinking Water

ReSource International is happy to announce that the company finalized its method development for microplastic counting in drinking water. Due to the difficulty of detecting and identifying microplastics, the method developed includes large samples as standard and uses fluorescence microscopy in laboratory quantification. Large efforts are also undertaken to quantify and prevent contamination in the sampling process, which has significantly affected most studies to date.

The project is done with the support and the participation of Orkuveita Reykjavikur, HS Orka (Reykjanes), Hafnarfjörður Municipality and Norðurorka (Akureyri).

Other water facilities are welcome to join the project and contact us for further information.


How Robots With Lasers Can Fight Climate Change: Mapping Landfill Methane Emissions with an UAV-​mounted Laser Sensor

These last weeks ReSource International has been testing a laser methane sensor supplied by Pergam Suisse on landfills in the southwest of Iceland. The sensor is normally used for ground-​based leak detection in the natural gas industry, and we have been able to mount it on one of our drones to detect methane leaks in the landfills which we work on. After processing raw data with our 3D elevation models using GIS software, we can create high-​resolution maps of emissions and compare them to visible and thermal photographs. Our goal is to be able to quantify emissions and thus monitor the effectiveness of the mitigation measures which we work with, such as gas collection systems and bio-​covers.

ReSource International has specialized itself for the past years in landfill monitoring and landfill gas collection systems. In addition, the company is operating a drone program, offering perfect opportunities to apply this technology to landfills.

Leak Detection on Hot Water Pipelines

ReSource International has successfully completed the detection of leakage on hot water pipelines. Our company is using drones equipped with a thermal camera to inspect several kilometres long hot water pipelines for the water facilities in Iceland. This method allows to document hot water leaks and can be applied even in remote areas. Using this method in partnership with the water facilities operators, it becomes possible to increase transport efficiency and reduce loss in hot water pipelines.


Measuring Microplastics in Landfill Leachate

In collaboration with the Swedish consulting company ÅF, ReSource has completed the sampling of two Icelandic landfills in Álfsnes and Fílfholt. The project is supported by the Nordic Co-​operation and the Swedish EPA and aims at the sampling and analysis of microplastics particles from landfill leachate.

During this project, the equipment designed and built by ReSource will be used in Iceland, Norway and Finland. The novelty of the equipment lays in the fact that large samples can be filtered straight on site, increasing the volume filtered and facilitating the processing of the samples for further analysis. Results will be published later this year.


Remote Sensing for Landfill Site in Iceland

The environmental engineering company ReSource International ehf. has signed an agreement with the municipal waste management company SORPA bs. (Great Reykjavík) concerning the use of regular drone surveys at their landfill site. ReSource has already developed in the past with SORPA some advanced monitoring method for the landfill gas collection system which resulted in more quantities and quality of the collected landfill gas used later on as biofuel for the capital area. The new agreement will push forward boundaries in landfill surveying and scientific knowledge in the field. Use of regular UAV geo-​surveys will help the landfill operator to save costs for daily operation and more accurately control their landfilling process in addition to collecting a new type of data relevant for research purposes. Furthermore, the partnership proposes to develop new methods to monitor landfill gas emissions based on laser technology and thermal mapping.

This new partnership is the achievement of the strong collaboration between SORPA and ReSource International and will offer new applications for UAVs in the field of environmental engineering and waste management.


Microplastics Research

Microplastics have been in the spotlight recently in Iceland following news about how widespread it is in wastewater in other countries. Wastewater treatment is limited in Iceland and microplastics are not actively removed from it. RSI has for the past year been working on method development for microplastics analysis in collaboration with Veitur and Hafnarfjarðarbær. Our main task was to develop scientifically valid sampling and analysis methods for microplastics in both wastewater and drinking water.

Plastic in Asphalt – Research Project

ReSource International is pleased to announce the award of a research grant from the Icelandic Technical Development Fund for a project to assess the technical possibilities of the addition of mixed waste plastic to asphalt.

The project will assess the technical feasibility of using mixed waste plastic, currently exported to Sweden for recycling and energy recovery, as an additive in hot mix asphalt. Numerous studies and real-​life evidence from India suggest that not only would this help solve an economic and environmental problem of waste, but that it could also strengthen asphalt considerably and increase its lifespan. As Iceland has an unforgiving climate and one of the highest lengths of road per capita in the world – almost 50m per person – this has the potential to have a large impact on the Icelandic economy.

RSI will also use its expertise in microplastic monitoring to conduct in-​depth assessments of any possible negative environmental effects from the process, including from road dust and leaching.

RSI will lead the project in partnership with two main Icelandic asphalt companies, Hlaðbær Colas and Malbikunarstöðin Höfði, the waste management company SORPA and the asphalt testing centre at the Icelandic Innovation Centre, and lifecycle assessments of the project will be conducted by a student from the Technical University of Denmark.
