Multiomics analysis of naturally efficacious lipid nanoparticle coronas reveals high-density lipoprotein is necessary for their function
In terms of lipid nanoparticle (LNP) engineering, the relationship between particle composition, delivery efficacy, and the composition of the biocoronas that form around LNPs, is poorly understood. To explore this we analyze naturally efficacious biocorona compositions using an unbiased screening workflow. First, LNPs are complexed with plasma samples, from individual lean or obese male rats, and then functionally evaluated in vitro. Then, a fast, automated, and miniaturized method retrieves the LNPs with intact biocoronas, and multiomics analysis of the LNP-corona complexes reveals the particle corona content arising from each individual plasma sample. We find that the most efficacious LNP-corona complexes were enriched with high-density lipoprotein (HDL) and, compared to the commonly used corona-biomarker Apolipoprotein E, corona HDL content was a superior predictor of in-vivo activity. Using technically challenging and clinically relevant lipid nanoparticles, these methods reveal a previously unreported role for HDL as a source of ApoE and, form a framework for improving LNP therapeutic efficacy by controlling corona composition.</p
Myndighetsdialog cirkulÀr ekonomi : Slutrapport
SamhĂ€llet stĂ„r för stora utmaningar vad gĂ€ller hĂ„llbarhet. DĂ€rför Ă€r det positivt att cirkulĂ€r ekonomi Ă€r pĂ„ uppgĂ„ng och att nya typer av produkter, tjĂ€nster och affĂ€rsmodeller utvecklas. Nuvarande lagar och regler Ă€r dock inte alltid i linje med den logik som följer av cirkulĂ€r ekonomi. Projektet Myndighetsdialog cirkulĂ€r ekonomi har syftat till att identifiera utmaningar och möjligheter relaterat till cirkulĂ€r ekonomi och produktrelaterad lagstiftning och krav, för att pĂ„ sĂ„ sĂ€tt underlĂ€tta cirkulĂ€r ekonomi i praktiken. Eftersom det Ă€r en ny praktik, sĂ„ finns olika tolkningar av produktlagstiftning i ljuset av cirkulĂ€ra produkter och produktflöden. I arbetet med att identifiera utmaningar och möjligheter Ă€r samarbete och kunskapsdelning mellan myndigheter och industri en viktig del. DĂ€rför har vi inom projektet bl.a. arrangerat tvĂ„ rundabordssamtal med myndigheter och bransch för att ha en samlad dialog. Ett viktigt mĂ„l för projektet har varit att bidra med guidning kopplat till cirkulĂ€r ekonomi och produktrelaterad lagstiftning och krav, för att underlĂ€tta ett mer cirkulĂ€rt och resurseffektivt samhĂ€lle. Men ocksĂ„ för att undvika att företag avvaktar med cirkulĂ€ra aktiviteter pĂ„ grund av osĂ€kerhet kring lagar och regler, bĂ„de nuvarande och kommande. Ett annat viktigt mĂ„l var att skapa en plattform för diskussioner kring cirkulĂ€r ekonomi, dĂ€r myndigheter och industri kan skapa en gemensam förstĂ„else för utmaningar och möjligheter kring cirkulĂ€r ekonomi. Slutsatserna frĂ„n projektet Ă€r flera. Den mest uppenbara Ă€r att den produktrelaterade lagstiftningen: ⹠Àr svĂ„r att tolka dĂ„ den bestĂ„r av mĂ„nga direktiv och lagar vilka inte Ă€r synkroniserade ⹠Àr otydlig kring vad som fĂ„r eller inte fĂ„r göras âą inte Ă€r anpassad för de olika strategier som en cirkulĂ€r ekonomi medför och som företag vill agera pĂ„ Mer specifikt finns ett behov bĂ„de av att olika cirkulĂ€ra begrepp lĂ€ggs till i lagstiftningen, och att dessa begrepp definieras och ensas mellan de olika lagstiftningarna och direktiven. Speciellt begreppet âny produktâ Ă€r svĂ„rtolkat vid cirkulĂ€ra flöden och cirkulĂ€rt designade och uppgraderingsbara produkter. Andra slutsatser Ă€r att det skulle underlĂ€tta för cirkulĂ€ra flöden och affĂ€rer om produktinformation kunde följa med produkten under dess livslĂ€ngd och olika anvĂ€ndningar, och att detta tillsammans med t.ex. standardisering skulle underlĂ€tta en mer situationsanpassad hantering av riskbedömning. Dessutom, i tillĂ€gg till lagstiftning, kan ekonomiska styrmedel dĂ€r kostnader för externaliteter inkluderas vara en kraftig möjliggörare för mer cirkulĂ€ra flöden. Sammanfattningsvis visar vĂ„r studie att de breda samtal som förts runt bordet med deltagare frĂ„n myndigheter och industri varit mycket uppskattade och öppnat upp för konstruktiv dialog med potential att göra skillnad, men ocksĂ„ att utmaningarna med att anpassa dagens produktrelaterade lagstiftning till mer cirkulĂ€ra produkter och flöden Ă€r stora, och att det troligtvis kommer att behövas omfattande förĂ€ndringar.With the contemporary sustainability challenges the world is facing, it is encouraging that circular economy is on the uprising and generates new type of products, services and business models. However, current laws and regulations are not always in line with the logic of a circular economy.The project Roundtable for circular economy aimed to identify challenges and opportunities regarding circularity and product related regulation and legislation, in order to facilitate circular economy in practice. Important in doing so, is the collaboration and knowledge sharing between authorities and industry. As this is a new practice, there are different interpretations of legislation and regulation. Therefore, in this project, two round tables were organized with authorities and industry in order to have a joint discussion on these issues. This was combined with an interview study with relevant actors.One important goal of this project was to aid with guidance concerning challenges and opportunities regarding circularity and product related regulation and legislation, for a more circular and resource efficient society, as to avoid inaction and uncertainty on how to act circular and within the legal boundaries, now and in the future. Another important goal was to have a platform for discussions on circular economy, where authorities and industry can create a common understanding of challenges and opportunities of circular economy.There are several conclusions from the project. The most obvious conclusion is that the product-related legislation is:âą difficult to interpret, as it involves many directives and laws which are not synchronizedâą ambiguous as to what may or may not be done and still fulfil legislationâą is not adapted to the different strategies that a circular economy entails and that companies wish to act uponMore specifically, there is a need both for different circular concepts to be added to the legislation, and for these concepts to be defined and harmonized between the various legislations and directives. The term "new product" in particular, is difficult to interpret in relation to circular flows and products designed for circularity and upgradeability. Other conclusions are that it would be easier for circular flows and business if product information could accompany the product during its service life and different uses, and that this, together with e.g. standardization, would facilitate a more pragmatic approach to risk assessment. In addition to legislation, economic policy where costs for externalities are included, could be a powerful enabler for more circular flows.In summary, our study shows that the broad conversations that took place around the table with participants from authorities and industry have been much appreciated and opened up for a constructive dialogue with the potential to make a difference, but also that there are huge challenges of adapting today's product-related legislation to more circular products and flows, and that major changes are likely to be needed

The connected, sustainable and inclusive society : IoT implementation in a Swedish municipality
The Internet of Things (IoT) is expected to transform the way we live, work, and learn. Using IoT could thus be a game-changer for municipalities towards sustainability. The Swedish municipality of SödertÀlje strives to develop IoT concepts and use open data for a sustainable and inclusive society. The goal of this study was to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The goal was also to enhance the knowledge of the environmental and social benefits of IoT systems in the waste collection system in SödertÀlje. The analysis is based on Life Cycle Assessment (LCA) and interviews. The results show a minor climate change impact for the IoT solutions in the overall smart waste collection system. The major climate impact contributor was instead associated with the trash bags used. Additionally, the study showed that the performance of the system relies on smart planning of the operations and the transportations.Original conference held October 2021. Selected presentations were invited to submit full conference papers to be included in proceedings published in May 2022.Det inkluderande, hÄllbara och uppkopplade samhÀlle
Det inkluderande, hÄllbara och uppkopplade samhÀllet : UtvÀrdering och framtidsanalys
SödertĂ€lje kommun har höga ambitioner att drastiskt sĂ€nka sin klimatpĂ„verkan och har ambitionen att inte ha nĂ„gra nettoutslĂ€pp av vĂ€xthusgaser Ă„r 2030 (SödertĂ€lje kommun Miljö- och klimatstrategi 2022â2030, 2022). För att nĂ„ dessa mĂ„l spelar avfallssektorn i SödertĂ€lje kommun en avgörande roll, vilket ocksĂ„ innebĂ€r ett behov av större involvering och ett större engagemang frĂ„n medborgare och företag. Som en del i det arbetet skapades projektet Det inkluderande, hĂ„llbara och uppkopplade samhĂ€llet. Projektet Ă€r ett samarbete mellan SödertĂ€lje kommun, Telge Ă
tervinning, RISE Research Institutes of Sweden och UmeĂ„ Universitet och avser att undersöka hur maskingenererad data kan ha dubbel nytta i att bĂ„de skapa externt medborgarvĂ€rde och internt organisatoriskt vĂ€rde i SödertĂ€lje kommuns omstĂ€llning till en hĂ„llbar stad. Denna rapport inkluderar en nulĂ€gesanalys över tre tematiserade omrĂ„den; digitalisering, livscykelanalys (LCA), och medborgardialog. SödertĂ€lje kommun har tillsammans med Telge NĂ€t byggt upp ett sĂ„ kallat LoRaWAN2 (ett trĂ„dlöst nĂ€tverk med dubbelriktad kommunikation3) i SödertĂ€lje för att underlĂ€tta kommunikation mellan sensorer i uppkopplade enheter. 169 papperskorgar har ocksĂ„ försetts med sensorer som mĂ€ter fyllnadsgrad, vilket genererat ett proof-of-concept för hur uppkopplad utrustning kan möjliggöra ruttoptimering och placeringsplanering. Att koppla upp en papperskorg har i det hĂ€r fallet inneburit att man fĂ€ster en sensor i locket pĂ„ befintliga kĂ€rl. Denna sensor kĂ€nner sedan av fyllnadsgraden i papperskorgens plastpĂ„se med jĂ€mna mellanrum. Initiativet kring uppkopplade papperskorgar har medfört inlĂ€rning pĂ„ flera nivĂ„er â sĂ„vĂ€l utvecklarna som utformar sensorerna, som medarbetarna som förlitar sig pĂ„ dem, har behövt tĂ€nka i nya banor och ompröva invanda arbetssĂ€tt. VĂ€rt att notera Ă€r att personalen behöver besöka samtliga omrĂ„den dĂ€r papperskorgar finns trots sensortekniken i och med att deras arbetsuppgifter Ă€ven inkluderar renhĂ„llning av gator och vĂ„rd av grönytor. Det vill sĂ€ga, det föreligger i nulĂ€get inte en kvantitativ ekonomisk vinst utan snarare en kvalitativ nytta i form av ökade möjligheter att planera sin arbetstid vilket kan leda till en renare stad. Bland de system som SödertĂ€lje kommun anvĂ€nder ses tvĂ„ som sĂ€rskilt intressanta i relation till Sakernas Internet (Internet of Things (IoT)) enligt denna nulĂ€gesanalys. PĂ„ en operativ nivĂ„ har Infracontrol potential att anta rollen som âspindeln i nĂ€tetâ dĂ€r status pĂ„ uppkopplad utrustning kan hanteras. PĂ„ en strategisk nivĂ„ erbjuder verktyget Maptionnaire möjligheter att aggregera, analysera, och presentera data frĂ„n uppkopplad utrustning. För att realisera potentialen hos dessa (och andra) verktyg krĂ€vs dock att SödertĂ€lje kommun stĂ€ller nya krav och utarbetar nya rutiner vid upphandling dĂ„ kostnaderna för att integrera uppkopplad utrustning annars skulle bli ohĂ„llbar. En LCA har genomförts för att utvĂ€rdera miljöpĂ„verkan frĂ„n sakernas Internet i SödertĂ€lje centrum för smart sophĂ€mtning ur ett livscykelperspektiv. Med koppling till kommunens klimatstrategi har miljöpĂ„verkan med fokus pĂ„ klimatpĂ„verkan prioriterats. Den visar att IoT-systemet enbart utgör en liten del av klimatpĂ„verkan (122 kg CO2-ekv per Ă„r4), vilket frĂ€mst hĂ€rrör frĂ„n gateways (50%) och sensorer (27%) och anvĂ€ndning av Internet (23%). SophĂ€mtningen bidrar med cirka 12 ton CO2-ekv per Ă„r, vilket frĂ€mst bidrog till anvĂ€ndningen av fossilbaserade avfallspĂ„sar i plast (96%) och Hydrerad Vegetabilisk Olja (HVO)-baserade transporter (4%). Vidare visar LCAn att potential för framtida klimatsmart sophĂ€mtningssystemet ligger inom minskad anvĂ€ndning av fossila plastpĂ„sar och smart planering av sophĂ€mtning för att reducera transporter. SödertĂ€lje har redan minskat sin klimatpĂ„verkan frĂ„n transporter (under 2016) genom byte frĂ„n diesel till HVO. För ett system med 169 papperskorgar (studiens utgĂ„ngspunkt) innebar detta 83% minskning, frĂ„n 2,3 ton till 380 kg. Enbart tvĂ„ ton av denna minskning hĂ€rrör frĂ„n fossilfria transporter (resp. 8,75 ton för ett möjligt framtida system med 700 papperskorgar). Dock visar resultaten att Ă€nnu mer klimatpĂ„verkan kan minskas genom att inte anvĂ€nda fossila plastpĂ„sar, nĂ€stan 12 ton (resp. 50 ton för 700 papperskorgar). Detta motsvarar fem resor till Thailand (2,5 ton per resa) eller utslĂ€pp för fyra invĂ„nare (2,8 ton per invĂ„nare) för Ă„ret 2030. För ett system med 700 papperskorgar betyder det minst 20 resor till Thailand eller utslĂ€pp för upp till 20 invĂ„nare per Ă„r. Vidare har projektet ett fokus pĂ„ inkludering av medborgare i frĂ„gor kring hĂ„llbarhet, med syftet att informera, engagera och inkludera medborgare i mĂ„let med att uppnĂ„ hĂ„llbar resurshantering. Medborgardialog kan ske pĂ„ mĂ„nga olika vis och innebĂ€ra olika saker. NulĂ€gesanalysen visar att flera olika aktiviteter genomförts pĂ„ omrĂ„det, och att dessa framförallt kan kopplas till kategorierna âinformationâ och âkonsultationâ, men dĂ€r ocksĂ„ det finns kommande inslag av âdialogâ med till exempel det Hackathon som planeras. FrĂ„n nulĂ€gesanalysen noterades dock en möjlighet till utökat fokus pĂ„ medborgardialog i SödertĂ€lje, samt att det finns en medvetenhet om behovet av att inkludera mĂ„nga olika grupper i denna dialog, men det noterades Ă€ven en utmaning vad gĂ€ller inkludering och olika sprĂ„k.Denna rapport Ă€r en del av projektrapporteringen för det Vinnovafinansierade projektet (en del av Strategiska innovationsprogrammet IoT Sverige1, en gemensam satsning av Vinnova, Formas och Energimyndigheten) Det inkluderande, hĂ„llbara och uppkopplade samhĂ€llet. Rapporten har fokus pĂ„ UtvĂ€rdering och framtidsanalys och Ă€r en pĂ„byggnadsrapport frĂ„n den tidigare projektrapporten om NulĂ€gesanalys. Med det avses att nuvarande rapport inkluderar aktiviteter som skett under senare delen av projektet, specifik inom arbetspaket (AP) 3 Konceptutveckling och AP4 Test och utvĂ€rdering.

REMAnufactuRing â Key enABLEr to future business (REMARKABLE)
Circularity through remanufacturing Remanufacturing can be described as a process of bringing used products to âlike-newâ functional state. It is an industrial process whereby products referred as cores are restored to useful life. During this process the core pass through a number of remanufacturing steps, e.g., inspection, disassembly, part replacement/refurbishment, cleaning, reassembly, and testing to ensure it meets the desired product standardsâ. Remanufacturing involves not only new processes but also necessitates changes in product design, the adoption of new business models, advancements in information management, and the inclusion of sustainability assessments. These assessments ensure that the new designs and circular business models implemented are not only circular but also sustainable. All these aspects form a crucial part of the REMARKABLE project, contributing to the development of a comprehensive remanufacturing ecosystem. The purpose of the REMARKABLE project is to support manufacturers to become more resilient, circular, and sustainable through remanufacturing and contribute to a more efficient use ofresources. Project activities and initial results The REMARKABLE project involves six highly engaged manufacturing companies from a variety of sectors that will collaborate during 2022-2025. At first, workshops have taken place with each company to identify needs, challenges and ambitions. In addition, five student projects have been conducted during spring 2022 along with two study visits at participating companies. Initial company discussions shows that remanufacturing tends to question current business models and generate grounds for circular business models development (e.g. leasing, rental, deposit system). Remanufacturing often also questions the current value network and the actors in it, as remanufacturing flows can generate need of new business relationships whilst maintaining current business models. Remanufacturing poses challenges due to small batch sizes, low automation, and reliance on manual labor. Flexibility and specific capabilities are needed to handle uncertainties, complexity in planning, and ensure efficiency. Tools, methods, and frameworks are necessary to effectively balance all three pillars of sustainability. The development process of remanufacturing systems plays a critical role in achieving sustainability performance which also requires effective information management. Commonly, the products are not adapted for remanufacturing. Within the REMARKABLE project we are investigating how to make the products easier to remanufacture by design. This includes for example aspects of making the product easier to clean and disassemble
