Research finds that the global market value of cargo bikes will hit 2.4 billion euros by 2031. Analysts with Future Market Insights assessing the growth of cargo bikes have placed the parcel courier industry as a key buyer of electric cargo bikes, forecasting that 43 per cent of sales could go to this industry. This growth is driven by city logistics trends, particularly as studies emerge showing the high efficiency and cost saving of the cargo bike versus the delivery van. It will not solely be direct incentives that drive uptake, however. The policy that restricts motoring and emissions is expected to be a key driver for businesses that seek profitability, with three-wheeled electric cargo bikes making up nearly half the market. The advance of e-bike technology has seen a strong rise in market share for assisted cargo bikes, now accounting for a 73 per cent market share. Potentially limiting the growth is the legislation governing the output and range of electric cargo bikes (FMI, 2021).To deal with the issues of faster delivery, clean delivery (low/zero emission) and less space in dense cities, the light electric freight vehicle (LEFV) can be–and is used more and more as–an innovative solution. The way logistics in urban areas is organized is being challenged, as the global growth of cities leads to more jobs, more businesses and more residents. As a result, companies, workers, residents and visitors demand more goods and produce more waste. More space for logistics activities in and around cities is at odds with the growing need for accommodation for people living and working in cities.

Motor learning is particularly challenging in neurological rehabilitation: patients who suffer from neurological diseases experience both physical limitations and difficulties of cognition and communication that affect and/or complicate the motor learning process. Therapists (e.g.,, physiotherapists and occupational therapists) who work in neurorehabilitation are therefore continuously searching for the best way to facilitate patients during these intensive learning processes. To support therapists in the application of motor learning, a framework was developed, integrating knowledge from the literature and the opinions and experiences of international experts. This article presents the framework, illustrated by cases from daily practice. The framework may assist therapists working in neurorehabilitation in making choices, implementing motor learning in routine practice, and supporting communication of knowledge and experiences about motor learning with colleagues and students. The article discusses the framework and offers suggestions and conditions given for its use in daily practice.

In their developmental model, Stodden et al. (2008) propose age-dependent relations between motor competence, physical activity,perceived motor competence, physical fitness, and weight status thatcan lead to a spiral of (dis)engagement. The goal of this study was toexplore these relations in a large sample of Dutch primary schoolchildren. To our knowledge, this is the first study including all fiveaspects of the model and a large sample of children between four andthirteen years old. Cross-sectional data was collected in 2068 children(ages 4–13), divided over 9 age groups. During physical educationclasses, they completed the 4-Skills Test, a physical activity question-naire, versions of the Self-Perception Profile for Children, Eurofit testand anthropometry measurements. Correlation coefficients per agegroup were calculated (full information maximum likelihood) andtransformed using a Fisher’s r to z transformation, after which thetest-statistic z was calculated. The results show that all five factors arerelated to each other and that a tipping point exists at which relationsemerge or strengthen. Physical fitness is related to motor competenceand physical activity and these relationships strengthen with age. Arelationship between BMI and the other four factors emerges in middlechildhood. Although the model described that physical activity stimu-lates motor competence in early childhood, our data showed that at ayoung age, both motor competence and perceived motor competencehad no relation with physical activity, while they were weakly related toeach other. In middle childhood, both motor competence and perceivedmotor competence were related to physical activity. Our findingsdemonstrate that children in late childhood who have higher perceivedmotor competence are also more physically active, have higher physicalfitness, higher motor competence and lower BMI. Our results indicatethat targeting motor competence at a young age might be a feasible wayto ensure continued participation in physical activities throughoutchildhood and adolescence.

Paper sludge contains papermaking mineral additives and fibers, which could be reused or recycled, thus enhancing the circularity. One of the promising technologies is the fast pyrolysis of paper sludge, which is capable of recovering > 99 wt.% of the fine minerals in the paper sludge and also affording a bio-liquid. The fine minerals (e.g., ‘circular’ CaCO3) can be reused as filler in consumer products thereby reducing the required primary resources. However, the bio-liquid has a lower quality compared to fossil fuels, and only a limited application, e.g., for heat generation, has been applied. This could be significantly improved by catalytic upgrading of the fast pyrolysis vapor, known as an ex-situ catalytic pyrolysis approach. We have recently found that a high-quality bio-oil (mainly ‘bio-based’ paraffins and low-molecular-weight aromatics, carbon yield of 21%, and HHV of 41.1 MJ kg-1) was produced (Chem. Eng. J., 420 (2021), 129714). Nevertheless, catalyst deactivation occurred after a few hours’ of reaction. As such, catalyst stability and regenerability are of research interest and also of high relevance for industrial implementation. This project aims to study the potential of the add-on catalytic upgrading step to the industrial fast pyrolysis of paper sludge process. One important performance metric for sustainable catalysis in the industry is the level of catalyst consumption (kgcat tprod-1) for catalytic pyrolysis of paper sludge. Another important research topic is to establish the correlation between yield and selectivity of the bio-chemicals and the catalyst characteristics. For this, different types of catalysts (e.g., FCC-type E-Cat) will be tested and several reaction-regeneration cycles will be performed. These studies will determine under which conditions catalytic fast pyrolysis of paper sludge is technically and economically viable.
