The free market underpins our economy and our way of thinking around enterprise and value, but it is also a major factor in the sustainability problems that we now live with. Climate change, child labour and oil spills are just a few of the many problems associated with our economic activity and, although many companies have made an effort to produce more sustainably, the pace of change is much too slow. This engaging and accessible textbook teaches students the relationship between the economy and sustainability, assessing the hand of the free market on company behaviour and, ultimately, providing a framework for transition to a sustainable economy. Using case studies and optional assessment questions, this textbook explains to students what a market is at the macro level and then translates the effects of the market to industries and subsequently to the strategic choices of companies at the micro level. It adopts a model of 8 guiding principlesthat underpin the current free market economy and 8 guiding principles for the sustainable market economy. Switching these deeply held principles will be essential to any serious transition to a sustainable economy.
In the Netherlands and some neighbouring European countries, the electric vehicle (EV) charging sector is receiving attention from market regulators. Concerns relating to competitive processes in this developing and rapidly growing sector are being raised. This paper identifies specific markets where regulation can help increase the level of competition for the development of affordable and accessible public charging infrastructure, both within the built environment (slow charging) as well as along highways (fast charging). Barriers to competition include exclusive concessions at the municipality level and long-term exclusive concessions at locations along highways.

Peer-to-peer (P2P) energy trading has been recognized as an important technology to increase the local self-consumption of photovoltaics in the local energy system. Different auction mechanisms and bidding strategies haven been investigated in previous studies. However, there has been no comparatively analysis on how different market structures influence the local energy system’s overall performance. This paper presents and compares two market structures, namely a centralized market and a decentralized market. Two pricing mechanisms in the centralized market and two bidding strategies in the decentralized market are developed. The results show that the centralized market leads to higher overall system self-consumption and profits. In the decentralized market, some electricity is directly sold to the grid due to unmatchable bids and asks. Bidding strategies based on the learning algorithm can achieve better performance compared to the random method.
Uit cijfers van het CBS zien we dat de vraag naar biologische producten achterblijft. De meerprijs die consumenten moeten neerleggen voor biologische productalternatieven blijkt een belangrijke belemmering te zijn voor de overstap naar biologisch. Hoe kunnen we deze gepercipieerde prijsbarrière bij de consument overkomen?
In this proposal, a consortium of knowledge institutes (wo, hbo) and industry aims to carry out the chemical re/upcycling of polyamides and polyurethanes by means of an ammonolysis, a depolymerisation reaction using ammonia (NH3). The products obtained are then purified from impurities and by-products, and in the case of polyurethanes, the amines obtained are reused for resynthesis of the polymer. In the depolymerisation of polyamides, the purified amides are converted to the corresponding amines by (in situ) hydrogenation or a Hofmann rearrangement, thereby forming new sources of amine. Alternatively, the amides are hydrolysed toward the corresponding carboxylic acids and reused in the repolymerisation towards polyamides. The above cycles are particularly suitable for end-of-life plastic streams from sorting installations that are not suitable for mechanical/chemical recycling. Any loss of material is compensated for by synthesis of amines from (mixtures of) end-of-life plastics and biomass (organic waste streams) and from end-of-life polyesters (ammonolysis). The ammonia required for depolymerisation can be synthesised from green hydrogen (Haber-Bosch process).By closing carbon cycles (high carbon efficiency) and supplementing the amines needed for the chain from biomass and end-of-life plastics, a significant CO2 saving is achieved as well as reduction in material input and waste. The research will focus on a number of specific industrially relevant cases/chains and will result in economically, ecologically (including safety) and socially acceptable routes for recycling polyamides and polyurethanes. Commercialisation of the results obtained are foreseen by the companies involved (a.o. Teijin and Covestro). Furthermore, as our project will result in a wide variety of new and drop-in (di)amines from sustainable sources, it will increase the attractiveness to use these sustainable monomers for currently prepared and new polyamides and polyurethanes. Also other market applications (pharma, fine chemicals, coatings, electronics, etc.) are foreseen for the sustainable amines synthesized within our proposition.
Our unilateral diet has resulted in a deficiency of specific elements/components needed for well-functioning of the human body. Especially the element magnesium is low in our processed food and results in neuronal and muscular malfunctioning, problems in bone heath/strength, and increased chances of diabetes, depression and cardiovascular diseases. Furthermore, it has also been recognized that magnesium plays an important role in cognitive functioning (impairment and enhancement), especially for people suffering from neurodegenerative diseases (Parkinson disease, Alzheimer, etc). Recently, it has been reported that magnesium addition positively effects sleep and calmness (anti-stress). In order to increase the bioavailability of magnesium cations, organic acids such as citrate, glycerophosphate and glycinate are often used as counterions. However, the magnesium supplements that are currently on the market still suffer from low bio-availability and often do not enter the brain significantly.The preparation of dual/multiple ligands of magnesium in which the organic acid not only functions as a carrier but also has synergistically/complementary biological effects is widely unexplored and needs further development. As a result, there is a strong need for dual/multiple magnesium supplements that are non-toxic, stable, prepared via an economically and ecologically attractive route, resulting in high bioavailability of magnesium in vivo, preferably positively influencing cognition/concentration
