Household organic waste recovery as key element for a circular economy

It is of utmost importance to collect organic waste from households as a separate waste stream. If collected separately, it could be used optimally to produce compost and biogas, it would not pollute fractions of materials that can be recovered from residual waste streams and it would not deteriorate the quality of some materials in residual waste (e.g. paper). In rural areas with separate organic waste collection systems, large quantities of organic waste are recovered. However, in the larger cities, only a small fraction of organic waste is recovered. In general, citizens dot not have space to store organic waste without nuisances of smell and/or flies. As this has been the cause of low organic waste collection rates, collection schemes have been cut, which created a further negative impact. Hence, additional efforts are required. There are some options to improve the organic waste recovery within the current system. Collection schemes might be improved, waste containers might be adapted to better suit the needs, and additional underground organic waste containers might be installed in residential neighbourhoods. There are persistent stories that separate organic waste collection makes no sense as the collectors just mix all municipal solid waste after collection, and incinerate it. Such stories might be fuelled by the practice that batches of contaminated organic waste are indeed incinerated. Trust in the system is important. Food waste is often regarded as unrein. Users might hate to store food waste in their kitchen that could attract insects, or the household pets. Hence, there is a challenge for socio-psychological research. This might also be supported by technology, e.g. organic waste storage devices and measures to improve waste separation in apartment buildings, such as separate chutes for waste fractions. Several cities have experimented with systems that collect organic wastes by the sewage system. By using a grinder, kitchen waste can be flushed into the sewage system, which in general produces biogas by the fermentation of sewage sludge. This is only a good option if the sewage is separated from the city drainage system, otherwise it might create water pollution. Another option might be to use grinders, that store the organic waste in a tank. This tank could be emptied regularly by a collection truck. Clearly, the preferred option depends on local conditions and culture. Besides, the density of the area, the type of sewage system and its biogas production, and the facilities that are already in place for organic waste collection are important parameters. In the paper, we will discuss the costs and benefits of future organic waste options and by discussing The Hague as an example.

Redelijke sociale verhoudingen, redelijk sociaal gedrag

Debates about social theory and social policy are highly fragmented and unclear in subject and direction. A recognised paradigm is failing. Maybe we have to accept that social reality is not to reconstruct in social theory. But we certainly need social theorists and social theories to support citizens, policy makers and social workers in improving social reality. Social reality in post modern societies is to be characterized by problematic relationships among citizens and between citizens and the public sector and by a sharp rise in problematic behaviour. The affluent society has failed to create a more sensitive world where people behave more socially. The dominant social problem is no longer seen from a social economic perspective but from a social cultural one. Social competences and social capital are considerer to be essential assets to cope with life in post modern society. For people weak ties and thin trust are essential to integrate into society. Thick trust and strong ties can bind people to much and cause inflexibility. The current social problem is a matter of designing a social world where relationships and behaviour are fair and reasonable. It asks for an interesting and creative social policy and social work, not too much stressing the problematic issues but encouraging people to trust each other. Current social policy is too much focused on the needs and problems. It has to change into a more expressive social policy, a policy that people challenges to express them and to create new relationships. Social behaviour asks for flexibility and creativity, for being authentic and playing roles. Scientists, policymakers, social workers and citizens are in the same field and have access to the same knowledge.

‘Een kunstgebit schoonmaken met groene zeep? Ik wist het niet’

In de media is er de laatste maanden veel aandacht besteed aan de slechte mondgezondheid van ouderen. Verpleegkundigen in de maatschappelijke gezondheidszorg kunnen een effectieve bijdrage leveren om de mondgezondheid bij hun cliënten te verbeteren. Het project Mondzorg ouderen, bewustwording onder zorgprofessionals van de Hogeschool Utrecht draagt bij aan het vergroten van de kennis van en bewustwording bij verpleegkundigen als het gaat om de mondzorg en mondgezondheid van hun cliënten.
