    Gipsavfall från bygg- och rivning, gipsanvändning inom jordbruk och vattenvård: Kunskapssammanställning2022Report (Other academic)
    Abstract [sv]

    Gips är ett mineral, ett naturligt hydrerat salt av svavelsyra och kalcium, som förekommer globalt i jordskorpan. Gipsavfall kan materialåtervinnas till 100% sett till grundråvaran gips, kalciumsulfat dihydrat. Åtgärder för utsortering från bygg- och rivningsverksamheter och återföring till industrin som sekundär råvara innebär en mer cirkulär hantering jämfört med att använda gipsavfallet som jordförbättringsmedel där möjligheten för cirkularitet bryts. Internationellt sett har man sedan länge använt naturgips som jordförbättringsmedel inom jordbruket. Erfarenhet och forskning har visat att alkalisk jord och tunga lerjordar kan erhålla förbättrade odlingsegenskaper. I tempererade länder som Sverige har gips däremot inte använts historiskt och det saknas forskning som visar på nyttan med gips på jordbruksmark i Sverige. Med Öland, Gotland och avgränsade områden i Västra Götaland undantaget har Sverige generellt svagt sura jordar i vilka gips inte visat sig ge förbättringar för markens odlingsegenskaper. Gipsavfall från bygg- och rivningsverksamhet och förbränning rekommenderas inte för användning inom jordbruk och vattenvård. Avfallet klarar inte kraven som ställs för användning inom livsmedelsproduktion som jordbruket eller miljövårdsinsatser som vattenvård. Åtgärder där naturgips tillsätts för att minska lakning av fosfor från jordbruksmark till sjöar och vattendrag har studerats i Finland inom projektet SAVE (Saving the Archipelago Sea by applying gypsum to agricultural field) som sedan 2016 studerat hur läckaget av fosfor kan minskas. Resultatet visar att läckaget av fosfor kan minskas med tillsatser av naturgips till alkaliska och svagt sura jordar. Det krävs dock omfattande insatser med en centralt organiserad projektstyrning samt att provningar, kontroller och uppföljningar utförs systematiskt över lång tid. Samma krav på gipsets ursprung och innehåll gäller som vid jordförbättring i produktionshöjande syfte.

    Ny teknik inom grisproduktionen2022Report (Other academic)
    Abstract [en]

    Investments in pig operations often involve investments in various technical equipment and systems. Automatic feeding and automatic regulation of the ventilation in pig units are commonly installed today. The future technologies, being under development, are more advanced technical solutions as the pigs' growth, behavior, well-being, and health are monitored with the aim to give the pig producer real time data of the production and eventually, what measures required to be taken. Precision Livestock Farming (PLF) aims to combine hardware, e.g., cameras, microphones and sensors, with computer software to collect and analyze data. By real time automatic monitoring, the production results and pigs’ welfare and health are easier to follow-up instantly. The PLF technology function as a warning system for disturbances in the pig units before the stockperson has had time to notice the changes making it possible for quick and targeted interventions. Different types of cameras are being developed to record different behaviors in pigs, such as aggressive behaviors. Face recognition, by a mobile phone application, is being developed for individual recognition of pigs and as a replacement of ear tags. In addition, attempts are made to monitor the pigs' activity and body measurements with camera technology to obtain information about pig health and growth. Finding a reliable system for automatic weight estimation of the pigs would gain profitability. Thermal cameras, IR technology, will be of great importance in pig production in the future. Other equipment already on the market are sensors for sound analysis with the aim to early detect any respiratory disturbances among the pigs. Prior to any technology investment, it is essential that the pig producer has been ensured that the system and equipment have been carefully tested, and especially applied in commercial herds. Some of the technologies presented in this report have only been tested in small herds and in controlled research environments, and therefore need further development before commercialization. Additionally, the technologies must have been tested under different production conditions, e.g., among different pig categories, housing conditions and pen designs. Future commercial technologies preferably include continuous monitoring of the individual pig's behavior, well-being, and health, along with production results and indoor environmental parameters. It is important that the techniques are developed based on the needs of the pig and the stockperson to avoid any inconveniences. The technologies must also be profitable and user-friendly.

    Potential to reduce climate impact with digitalisation in agriculture – literature review and a case study of milk2021Report (Other academic)
    Abstract [en]

    The agricultural sector in Sweden needs to reduce greenhouse gas (GHG) emissions. Digitalisation has the potential to contribute to this reduction. The term digitalisation is used to describe a process for digital transformation of products and processes. The purpose is to enable better decisions by using an increased insight through collecting data, and to process the collected data using different smart algorithms. In this report, we present a literature review on research of the potential to reduce climate impact with digitalisation in agriculture. The result of the literature review was applied on a case study, where different scenarios with varying degrees of digitalisation were tested to quantify possible reductions in GHG emissions when introducing digitalisation techniques at a Swedish dairy farm. The results shows that implementation of various digitalisation technologies at a Swedish dairy farm has a potential to reduce the carbon footprint of Swedish milk by 16 %. Precision livestock farming shows the largest potential with an estimated reduction of 14 %, primarily due to feed efficiency and improved animal health and longevity, reducing the total number of animals while maintaining high milk output. It is however important to evaluate the whole system, as changes in the dairy system might impact other farms and food producing systems. This indicates a need for research to further investigate the potential GHG reduction when introducing digitalisation in agriculture.
