Pyrolysis Products as Soil Fertilizers: Screening of Potentially Hazardous Aromatic Compounds
This study investigated the concentrations of polycyclic aromatic hydrocarbons (PAHs) in pyrogenic carbonaceous materials (PCM) produced from three waste materials during slow pyrolysis at 400 and 500°C.

Nutrient balance of a two-phase solid manure biogas plant [PDF]
So called "dry fermentation" prototype plants for anaerobic digestion of organic material containing 15-50 % total solids show added advantages compared to slurry digestion plants (Hoffman 2001): Less reactor volume, less process energy, less transport ...

Environmental Dynamics in Animal Waste Reclamation in the Scaling up of Livestock in Thailand [PDF]
Thailand has seen a scaling up of pig production in numbers and structure. Nonetheless, in-house separation and agricultural reclamation of pig solid waste are common practice.

Effects of Three Biochars as Adsorbents on Soils Adsorbing Ammonium Nitrogen in Biogas Slurry
The increasing concern of biogas slurry disposal and nitrogen loss in soils has brought back the interest in using biochar as an adsorbent of biogas slurry in soils. Three types of biochars, commercial activated carbon, pyrolysis productions derived from

Comparative Biogas Generation from Cow Rumen Waste and Human Fecal Slurry at Different Retention Times [PDF]
The generation of biogas from cow rumen waste and human fecal slurry at different retention times was investigated. Microbial growth, pH, and the volume of biogas produced from the two substrates were monitored over a 60-day retention period ...

Biogas on-farm: energy and material flow [PDF]
Objectives: European countries are committed to reduce CO2 emission originating from fossil fuels. On-farm produced biogas may replace energy produced from fossil fuels and so contribute to achieve the target. Up to now only in Germany a greater number

Biogas production from renewable lignocellulosic biomass
Effect of raw and biologically treated lignocellulosic biomass using cow dung slurry for biogas production is reported. Biomass is an energy source. Water containing biomass such as sewage sludge, cow dung slurry and lignocellulosic waste, has several ...
