Unfortunately an incorrect version of Figure 4 appears on p517 of this paper; the correct version is as printed below. A sentence (“Increased N2O emissions…. Conversely”) should then also be deleted from the corresponding paragraph of the main text as printed on pp516–517; the correct version of this paragraph is also given below. The authors and publisher regret any confusion or inconvenience this may have caused.

Change Impact

Nitrous oxide (N2O) and methane (CH4) emissions from the wastewater sector represent the second largest source of greenhouse gas (GHG) emissions of the waste sector. A protocol has been developed to measure GHG from sewage sludge treatment. GHG measurements were performed on two industrial sewage sludge composting plants. Measurement campaigns showed GHG emissions range between 0.18 to 3.40 kgCH4\t dry sludge and 0.74 to 0.48 kg N2O\t dry sludge. Converted to CO2 equivalent to assess climate change impact, emission factors of CH4 range between 4.5 and 85 kg eq.CO2\t dry sludge and N2O range between 143 and 221 kg eq.CO2\t dry sludge when calculated with global warming potentials (GWP) of 25 and 298, respectively. In terms of climate change impact, N2O emissions contribute much more than CH4 because of its higher GWP. N2O is linked to the treatment of nitrogen and produced during the nitrification and denitrification biological processes. Process emissions measured on the two sites were compared with indirect emissions linked to operational energy use.

An energy consumption model was developed for evaluating sewage sludge treatment plants (SSTPs) incorporating various treatment processes such as thickening, anaerobic digestion, dewatering, incineration, and melting. Based on data analyses from SSTPs in Osaka, Japan, electricity consumption intensities for thickening, anaerobic digestion, dewatering, incineration, and melting and heat consumption intensities for anaerobic digestion, incineration, and melting were expressed as functions of sludge-loading on each unit process. The model was applied for predicting the energy consumption and greenhouse gas (GHG) emissions of SSTPs using various treatment processes and power and heat generation processes using digestion gas. Results showed that SSTPs lacking incineration and melting processes but having power generation processes showed excess energy production at the high sludge-loading rate. Energy consumption of the SSTPs without incineration and melting processes were low, but their GHG emissions were high because of CH4 and N2O emissions from sludge cake at the landfill site. Incineration and melting processes consume much energy, but have lower CH4 and N2O emissions.

All Animals Are Equal, or Are They? The Ikhwān al-Ṣafāʾ’s Animal Epistle and its Unhappy End

Privileged Status

The Ikhwān al-Ṣafāʾ’s animal epistle is an intriguing work. Although in the body of the narrative the authors challenge anthropocentric preconceptions and present nonhuman animals in a more favourable light than human beings, inexplicably, the narrative ends by reconfirming the privileged status of humans. The aim of this paper is to propose an explanation for this discrepancy. I argue that the egalitarian message reflected in the body of the narrative is traceable back to the Qur'an, the main text with which the authors engage in the fable, whereas the final outcome is due to the Ikhwān's hierarchical worldview.
