Extended Producer Responsibility in East Asia: Approaches and lessons learnt from the management of waste electrical and electronic equipment

Environmental protection has become high in the policy agenda of East Asian countries by the end of the last century due to both internal and external stimuli. One of the main environmental issues is the management of solid waste. The concept of circular economy which encourages reduce, reuse, and recycling, i.e. 3Rs, together with the principle of Extended Producer Responsibility (EPR) has been p

Can I be an Instantaneous Stage and yet Persist Through Time?

Abstract in Undetermined An alternative to the standard endurance/perdurance accounts of persistence has recently been developed: the stage theory (Sider, 2001; Hawley, 2001). According to this theory, a persisting object is identical with an instantaneous stage (temporal part). On the basis of Leibniz’s Law, I argue that stage theorists either have to deny the alleged identity (i.e. give up their

Ord

Vad är ett ord? Hur många ordklasser finns det egentligen? Finns det några begränsningar på vilka nybildningar som kan göras? Hur lär sig ett barn hur orden ser ut i det egna modersmålet? Ovanstående frågor är några av de som Ord försöker ge svar på. Boken är en modern ordbildningslära som kombinerar klassisk ordbildningsteori med de senaste rönen inom grammatisk forskning.

Activated Wet-Dry Scrubbing of SO2

A new concept for enhancing wet-dry scrubbing of SO2 has been tested on a laboratory and pilot scale. By adding small amounts of promotor, e.g. calcium chloride, to a limestone or lime slurry, a considerable increase in the removal efficiency can be obtained. The experimental findings in a 0.5 MW wet-dry pilot indicate promoted limestone to be a feasible option for SO2 removal when burning low sul

Biological removal of chlorinated organic compounds from kraft bleaching plant effluent

Popular Abstract in Swedish Vid blekning av pappersmassa använd i många fall klorinnehållander blekkemikalier. Detta resulterar bildandet av olika klororganiska föreningar som hamnar i avloppsvattnet. Många klororganiska föreningar är giftiga och skadliga för miljön. För att minska utsläppen av dessa föreningar kan avloppsvattnet renas innan det släpps ut. I detta doktorsarbetet har nedbrytningen The microbial decomposition of chlorinated organic compounds in kraft bleaching plant effluent (KBPE) was studied. An aerobic bacterium, Strain TCA1, able to grow on trichloroacetic acid as the sole source of energy and carbon was isolated and characterized. Cultivations of Strain TCA1 and another bacterium, Strain DCA1, on acetic acid and its chlorinated analogues mono-, di-, and trichloroacetic
