This report summarizes the main findings of the research conducted within the CircWOOD project during the period 2022-2026 and presents key recommendations for decision-makers towards wood reuse in the construction sector. CircWOOD aimed to enable and support a transition to a sustainable, competitive, and technologically optimized circular wood value chain through a transdisciplinary research approach. The project was carried out by five research institutions and universities, exploring technical, environmental, economic, and social dimensions in the value chain. Our research findings demonstrate potentials for wood reuse, while also highlighting a variety of practical and market-related challenges. The report presents eight key recommendations for policymakers, industry stakeholders, and other decisionmakers to drive wood reuse. Improving sorting systems and quality control for wood waste from construction and demolition activities and prioritizing deconstruction over demolition can enable reuse. Developing supporting infrastructure such as material banks, reuse centers, and logistics systems is also important. Wood reuse can create new opportunities for businesses, while continued research, better data, and AI can strengthen decision-making and support a more resource-efficient built environment.

A workshop was held during the VII International Symposium on Postharvest Pathology (held in conjunction with the IX International Postharvest Symposium and the X International Symposium on Human Health Effects of Fruit and Vegetables) to discuss reducing fungicides in orchards for controlling postharvest diseases. This article summarizes the discussion that was guided by four convenors (Burlakoti, Wenneker, Lennox, Alkan), stimulated by the two organizers (Scheper, Everett), and contributed to by 45 workshop participants. Alternative treatments and procedures discussed included the importance of an elucidated disease cycle and knowledge of pathogen biology to target control strategies. Also discussed were novel/unconventional controls such as inducing a defense response or RNA interference, biocontrol including new knowledge of the microbiome, manipulation of the environment and physical treatments. Given the complexity of fruit decay and pathogen resistance processes, a combination of treatments is likely to be the best solution. For instance, combining physical treatments like UV-C exposure with biological priming or chemical agents could result in synergistic effects that enhance resistance more effectively than any single treatment alone.

Core rot in apple has only been considered a problem in a limited number of cultivars and has not been a focus in Norway, or in many other countries. There is currently a high demand for apple juice and cider in Norway. As core rot is not detectable on the fruit surface until the rot reaches the outer fruit flesh, it is possible for infected fruit to be used for juice without noticing the rot. Since Fusarium spp., one of the known causes of core rot, is a known producer of mycotoxins, precautionary investigations are needed. Over several seasons it was found that both pre- and postharvest rot of Fusarium spp. were common on most of the cultivars grown in Norway. As in other countries, Fusarium avenaceum has dominated so far, but Fusarium paeoniae was also identified on apple. Inoculation experiments with attached fruit and in storage were successful both in establishing core rot and detecting different mycotoxins from the fruit. There were differences between isolates of F. avenaceum in both the type of mycotoxins produced and the amount. A potential life cycle for Fusarium spp. on apple fruit in Norway is suggested, and possible ways of reducing the incidence both pre- and postharvest are discussed.

A functional and low-impact forest road network is essential for sustainable forest management, yet maintaining such infrastructure is costly and requires monitoring tools that are reliable and simple enough for operational use. We present an automated approach to detect, map, and evaluate forest road surface deterioration, designed to support end-users, including those with limited road expertise, to indicate required maintenance actions. The system relies on data collected by the vehicle-mounted near-field sensor platform RoadSens, which integrates stereo camera imagery with GNSS-based geo-referencing to capture detailed road surface information. Collected data are processed within a monitoring and scheduling environment using a YOLOv8 object detection model trained on nearly 14,000 annotated images. The model identifies six key deterioration features: potholes, wheel ruts, gullies, washboards, stones, and vegetation. These detections are used to locate maintenance-relevant features and classify road segments into three deterioration levels based on coverage thresholds, which are then visualized through a traffic-light system. A case study on a forest road in southern Norway demonstrated the system’s ability to detect and classify maintenance needs. While performance was strong for more uniform features such as vegetation, irregular structures like wheel ruts proved more challenging, occasionally leading to misclassification of actual maintenance requirements. Nevertheless, the findings confirm the technical feasibility of integrating object detection models into data-driven forest road maintenance scheduling. Future improvements will require larger and more diverse training datasets, as well as classification frameworks tailored to local conditions and specific road-user needs.309671

In Norway, plum fruit is sold for fresh consumption in a similar way as sweet cherry for a high price. Different treatments were tested to ensure high quality at the consumer end. The fruit is normally picked with a range in ripeness. At packaging grading the fruit in different maturity classes for intended sale in shorter (Ripe+) and longer channels (Ripe-) has been partially implemented in the industry. As a further improvement, application of 1-methylcyclopropene (1-MCP) was tested on fruit of the two ripeness categories of two cultivars. After a period of cold storage and simulated shelf-life for two days at 20°C fruits were tasted by a sensory panel. Fruit quality and fungal decay were assessed both after cold storage and simulated shelf-life. It was clear that taste of less ripe fruit was associated with firmer fruit, more acidity and greener taste, and quality of riper fruit was associated with sweetness, higher colour value, softer texture and a higher taste intensity. The panel found that treated Ripe- fruit had a greener taste and flavour and were less juicy and less sweet. In general, quality analysis of less ripe plum fruit of both cultivars showed that they had higher content of acids, were firmer, and had less cover colour after storage compared to riper fruits. Also, treatment with 1-MCP impacted firmness, colour, and acidity. However, the treatment effect was different depending on cultivars and years. In 2022, the effect of 1-MCP was seen for both ripeness categories of ‘Reeves’, but only for Ripe- fruit in 2023. There was no effect of 1-MCP treatments on ‘Mallard’ in 2022, however, there was a slight effect of 1-MCP on firmness, acids and cover colour after self-life test for less ripe plum fruit in 2023. The Ripe+ fruit developed 2-10 times more fungal fruit decay than less ripe fruit. 1-MCP had no effect on development of fungal fruit decay. Preliminary conclusion was that management of fruit maturation is more effective than 1-MCP application in securing consumer end quality.

Evaluating the effect of different treatments after a simulated shelf life is common in postharvest industry experiments. As fungal fruit decay development is closely linked to preharvest factors, fruit quality, and postharvest treatments two other time points were added in recent experiments. When commercial packinghouses graded the different experimental units (from 1 to 4 bins) they made three different samples; 1) all the fruit manually discarded before size grading (mostly external symptoms of fungal fruit decay and physiological disorders), 2) a 100-fruit sample of the fruit not regarded as first class by the grading machine at size grading (fruit that could be used for industry purpose, processing fruit), and 3) packed fruit for shelf life testing. As expected, differences in pathogen presence were found varying with storage time, cultivar, season, treatments, etc., but overall, some important factors could be pointed at: up to 70% of the processing fruit had damages (caused by insects, weather or mechanical damage) that could be an entry point of fungal pathogens in storage. Apple scab was found on up to 60% of that fruit and up to 12% of the graded fruit in shelf-life tests, indicating a less effective fungicide strategy in some of the commercial orchards. The additional knowledge gained by having three sample types in the experiments is discussed.

RESTORE jobber med restaurering av artsrike naturtyper i kulturlandskapet. Disse naturtypene er formet gjennom langvarig tradisjonell skjøtsel, som beite, slått og brenning, og er viktige leveområder for mange arter. I dag er mange av dem truet av opphør av skjøtsel, gjengroing, intensivering av landbruket og nedbygging. Prosjektet bidrar med kunnskap om hvordan forringet natur kan føres tilbake til god økologisk tilstand — blant annet gjennom rydding, fjerning av problemarter og gjeninnføring av tradisjonell skjøtsel.
