Product service systems (PSS) are an example of a novel business model billed as having the potential to significantly reduce the environmental burdens of production and consumption processes. However, despite widespread interest in PSS, consensus regarding their actual environmental impacts, particularly with regard to salient issues such as global warming, is lacking. Hence this paper explores existing research to investigate the state of the art regarding the climatic impacts of PSS, alongside the set of factors that influence climatic impacts. The paper comprises a systematic review of peer-reviewed academic literature, quantifying the extent to which different types of PSS have the capacity to reduce greenhouse gas emissions across multiple product categories. Our study shows that significant reductions in climatic emissions are possible, but PSS are in many cases associated with more modest reductions and, in some cases, increased emissions. Further, we observe no clear differences in climatic impacts according to the type of PSS model that is deployed. Rather, differences in climatic impact are influenced by factors such as production and design alongside use-phase impacts and contextual factors such as transportation and the energy mix. The study argues that further research is needed to establish a more robust baseline upon which to draw conclusions regarding the sources of climatic impacts, and outlines fruitful ways for companies to tackle the complexities of climatic emissions that are beyond their control.

Immense beyond imagination, the untamed rainforests of western New Guinea represent a biodiversity hotspot, home to several unique species of flora and fauna. The territory’s astonishing beauty and diversity is underpinned by a stunning array of natural resources. The island is also home to many indigenous communities practicing hundreds of local languages and traditions and depending on their natural environment for maintaining their traditional livelihoods, identity and culture. The territory’s much-contested decolonization process in the 1950-60s led to widespread discontent among indigenous Papuans and gave rise to persistent dissent from Indonesian rule, routinely met with disproportionately violent action by Indonesian security forces. Adding to these longstanding colonial ills and grievances, indigenous Papuan communities also struggle to grapple with inequitable allocation of land and resources, extreme pollution and environmental degradation caused by the mining and palm oil sectors. In the meantime, climate-exacerbated weather events have become more frequent in the region creating new tensions by putting an additional strain on natural resources and thus leading to an increased level of insecurity and inequality. In particular, these challenges have a disproportionate and profound impact on indigenous Papuan women, whose native lands are deeply embedded in their cultural and ethnic identity, and who are dependent on access to land to carry out their prescribed roles. Displacement also puts women at further risk of violence. Adding to sexual violence and displacement experienced by indigenous Papuan women, the loss of traditional lands and resources has been identified as having a singularly negative impact on women as it impedes their empowerment and makes them vulnerable to continued violence. The Papuan experience thus serves as a timely illustration to exemplify how environmental factors, such as resource extraction and climate change, not only amplify vulnerabilities and exacerbate pre-existing inequalities stemming from colonial times, they also give rise to gendered consequences flowing from large-scale degradation and loss of the natural environment.
Many citizens experience ambivalence – having simultaneously positive and negative evaluations – about changing their behaviour towards a more environmentally friendly lifestyle. Based on 36 studies, this study identifies and synthesises the current evidence on how ambivalence impacts environmental behaviours. In most studies, ambivalence is shown to be directly and negatively associated with environmental behaviours, i.e., higher levels of ambivalence are linked to lower levels of environmentally friendly and unfriendly behaviours. This applies to both types of ambivalence: objective (OA) and subjective (SA). Mediator analyses show, in line with the theory, that SA, not OA, drives behavioural change. In addition, results indicate that ambivalence moderates the relationship between independent–dependent variables mainly negatively, for example, by weakening attitude–behaviour relationships. This review shows the potential of ambivalence to facilitate behaviour change: SA about environmentally friendly behaviour can hinder, whereas SA about environmentally unfriendly behaviour can motivate, behaviour change. In addition, this review highlights some significant knowledge gaps in this body of research. A lack of validated standardised measurements of ambivalence makes it challenging to compare studies and reach conclusions about underlying theoretical constructs. Methods, research designs, and theoretical underpinnings need improvement to fully understand ambivalence and progress towards the transition of environmentally friendly behaviours.

Currently, many novel innovative materials and manufacturing methods are developed in order to help businesses for improving their performance, developing new products, and also implement more sustainability into their current processes. For this purpose, additive manufacturing (AM) technology has been very successful in the fabrication of complex shape products, that cannot be manufactured by conventional approaches, and also using novel high-performance materials with more sustainable aspects. The application of bioplastics and biopolymers is growing fast in the 3D printing industry. Since they are good alternatives to petrochemical products that have negative impacts on environments, therefore, many research studies have been exploring and developing new biopolymers and 3D printing techniques for the fabrication of fully biobased products. In particular, 3D printing of smart biopolymers has attracted much attention due to the specific functionalities of the fabricated products. They have a unique ability to recover their original shape from a significant plastic deformation when a particular stimulus, like temperature, is applied. Therefore, the application of smart biopolymers in the 3D printing process gives an additional dimension (time) to this technology, called four-dimensional (4D) printing, and it highlights the promise for further development of 4D printing in the design and fabrication of smart structures and products. This performance in combination with specific complex designs, such as sandwich structures, allows the production of for example impact-resistant, stress-absorber panels, lightweight products for sporting goods, automotive, or many other applications. In this study, an experimental approach will be applied to fabricate a suitable biopolymer with a shape memory behavior and also investigate the impact of design and operational parameters on the functionality of 4D printed sandwich structures, especially, stress absorption rate and shape recovery behavior.
Due to the existing pressure for a more rational use of the water, many public managers and industries have to re-think/adapt their processes towards a more circular approach. Such pressure is even more critical in the Rio Doce region, Minas Gerais, due to the large environmental accident occurred in 2015. Cenibra (pulp mill) is an example of such industries due to the fact that it is situated in the river basin and that it has a water demanding process. The current proposal is meant as an academic and engineering study to propose possible solutions to decrease the total water consumption of the mill and, thus, decrease the total stress on the Rio Doce basin. The work will be divided in three working packages, namely: (i) evaluation (modelling) of the mill process and water balance (ii) application and operation of a pilot scale wastewater treatment plant (iii) analysis of the impacts caused by the improvement of the process. The second work package will also be conducted (in parallel) with a lab scale setup in The Netherlands to allow fast adjustments and broaden evaluation of the setup/process performance. The actions will focus on reducing the mill total water consumption in 20%.
Duurzame ontwikkeling staat hoog op lokale, nationale en internationale politieke agenda’s. Denk alleen al aan klimaatverandering, biodiversiteit, de stikstofcrisis, de gezondheidscrisis, de teloorgang van stilte en stiltegebieden en de ontwikkeling van de circulaire economie.Duurzame ontwikkeling bestaat nadrukkelijk uit aspecten op het gebied van milieu, mens en economie. Daarbij is het perspectief van de stakeholders in de sector, de bedrijven, overheden, omwonenden, klanten en belanghebbenden van groot belang.De gastvrijheidssector speelt hierin een dubbele rol: enerzijds creëren deze sector veel waarde uit natuurlijke hulpbronnen zoals juist de kwaliteit van natuur, biodiversiteit, landschap, stilte, schone lucht. Anderzijds speelt de sector een rol bij het ontstaan van klimaatverandering, stikstofoxiden, verlies van biodiversiteit en stilte.Het project beoogt voor bovenstaande problematiek een onderzoekagenda op te stellen. De onderzoekagenda geeft een systematisch overzicht van de problematiek, een vertaling naar de potentiële onderzoeksvragen en mogelijke resultaten.Partners: Hogeschool Zeeland (HZ), NHL/Stenden.
