The roles of the state and social licence to operate? Lessons from nuclear waste management in Finland, France, and Sweden
2019
The concept of social licence to operate (SLO) is an increasingly popular tool for companies to manage their relations with the local communities. SLO is very seldom used in the nuclear sector, which has nevertheless applied similar approaches, under notions such as partnership and participatory governance. This article explores the specific challenges that the application of SLO faces in the nuclear waste management (NWM) sector, by applying an often-used SLO framework of Boutilier and Thomson to illustrative case studies concerning nuclear waste repository projects in Finland, France and Sweden. Among the specificities of this sector, the article focuses on the central roles of the state …
Effects of biochar addition on anaerobic digestion and comparison of different biochar qualities
2017
Tässä pro gradu -työssä tutkittiin, voidaanko anaerobisen mädätyksen toimintaa parantaa lisäämällä mädätysprosessiin pieniä määriä biohiiltä. Anaerobista mädätystä tutkittiin laboratoriomittakaavan biokaasukokeilla, joissa biokaasureaktoreita käsiteltiin sekä pyrolyyttisesti että hydrodermaalisesti tuotetulla biohiilellä. Biohiilen mahdolliseen kykyyn lievittää ammoniakki-inhibitiota kiinnitettiin huomiota. Seitsemän pyrolyyttisen ja yhden hydrodermaalisen hiilen ominaisuuksia vertailtiin, jotta voitaisiin määrittää soveltuvia biohiiliä anaerobiseen mädätykseen. Biohiilistä analysoitiin ammonium-adsorptiokapasiteetti, irtoavan liukoisen orgaanisen kokonaishiilen (DOC) ja liukoisen kokonaist…
A technological approach towards integrated solid waste management in developing countries
2017
This research is grounded in the planning concept of Integrated Solid Waste Management (ISWM). ISWM was developed to promote sustainability in the waste management for developing countries. Waste managers and policy makers in developing countries have been adopting the principles of ISWM into their waste strategies for several decades. But despite their many efforts, still important problems remain, as is the case of low collection coverage, lack of proper treatment of the different waste types, high dependency on final disposal sites and even in some cities uncontrolled dumping is still accepted as the only way to handle the waste. For that reason, waste management in developing countries …
