| Thermophilic composting of faecal matter from urine diverting toilets can effectively reduce the numbers of faecal bacterial indicators and pathogen. Already at 50C, the numbers of pathogens, including the Salmonella phage, and indicator organisms analysed were effectively reduced within a few days of exposure. Although the numbers of enterococci were reduced, they were continuous isolated as purple colonies on Slanetz and Bartleys agar after prolonged exposure at all temperature levels studied. This indicates that certain micro-organisms present in the composted faecal material, Enterococcus spp. or micro-organisms resembling enterococci on the agar medium, can survive and multiply even at 60C. These findings question the use of enterococci as faecal... |

| Organic farmers are concerned about the use of genetically modified plants (GM plants) in conventional agriculture. The concern is mainly focused on the risk of spreading of pollen or seeds from GM plans to adjacent fields. There has been less focus on the environmental impact of exposing the soil to genetically modified DNA (i.e. transgenic DNA) from GM plants residues left in the field. Yet, the new EU directive on the deliberate release into the environment of genetically modified organisms (EU, 2001) requires a "description of post-release treatment methods for the genetically modified plant material including wastes". |

| Large variations in numbers of faecal indicator bacteria were found irrespective of the storage time of collected human faeces. Little heat seemed generated from composting processes when bin units were stored locally in households. The low reduction in microbiological parameters and very limited temperature increase were generally corroborated by the results obtained in experiment 2 when pathogen indicators were added to thoroughly mixed faecal matter. Even though Salmonella died of rapidly the other faecal bacterial indicators survived in large numbers. We conclude, that the collection and storage of human faeces in the closed plastic bins studied here is associated with only little temperature increase and subsequent reduction in faecal bacterial... |

| Biological treatment of organic waste by aerobic composting and anaerobic digestion (biogas production) was compared with respect to a number of environmental effects and sustainability criterias including energy balance, nutrient recycling, global warming mitigation potential, emission of xenobiotic compounds and economy. The parameters were assessed based on case studies in the literature as well as our own research. Assessment of energy balance, nutrient recycling and global warming came out in favour of biogas production, but especially the results regarding estimation of global warming mitigation differ according to the assumptions made. Our calculations showed that a fugitive loss of approx. 14% of the biogas produced by anaerobic digestion will turn... |

| Short-Circuit is an on-going EU-LIFE ENVIRONMENT funded project (KVL is project leader) with the aim of 'short-circuiting' the carbon and nutrient cycle between urban and rural districts by establishing three new systems for source separation, collection and composting of organic waste in the greater Copenhagen area. The project is a collaboration between research institutions (KVL and Küngl. Tekniska Högskolan in Stockholm), and industry represented by the composting firm Solum Ltd. and the Internet-based box scheme business Aarstiderne Ltd. KVL´s part of the activity is co-funded by the Danish Research Centre for Organic Farming, via the CRUCIAL project. These two projects form part of a coherent effort to re-invent urban waste management with... |

| Som resultat af projekterne kan drages følgende hovedkonklusioner om kompostering af fæces fra mennesker: Fæces fra de undersøgte typer af kompostbeholdere bør ikke anvendes til jordbrugsformål uden viderebehandling, da dette skønnes at være behæftet med hygiejne- og sundhedsrisici. Det skyldes, at der ikke blev dokumenteret egentlige termofile temperaturstigninger i fæcesmaterialet i komposttoiletenhederne i Hjortshøj, Dyssekilde og Sverige, og at fækale indikatorbakteriers antal varierede voldsomt, og der ingen entydig tendens var til forekomst af lavere kimtal ved lange opbevaringstider af de opsamlede fækalier. |

| Using denaturing gradient gel electrophoresis (DGGE) and simultaneously measure the enzymatic activity of chitinase, we could link genetic and functional diversity of the indigenous microbial communities in compost samples. Two types of compost, a garden/park waste compost (D-Gro A) and a source separated organic household waste compost (Biovækst), showed different genetic diversity as measured by PCR-DGGE of total DNA extracted from the composts. The composts also had different chitinase activity, 0.46 and 3.97 µmole 4MU/hour x g dry matter for the D-Gro A and Biovækst composts, respectively. To increase chitinase activity the two composts were amended with chitin. This addition induced a change in both the bacterial and fungal genetic diversity when... |
