Introduction This paper reports the influence of vermi-composts prepared from cow dung and house hold waste on the growth and flowering of marigold crop. A total of seven potting media were prepared containing soil, cow dung vermicompost... more
Background King oyster mushroom (Pleurotus eryngii) contains many medicinal and nutritional values, excellent flavors, and a long shelf life. Cultivation of edible mushroom on agricultural and lignocellulosic waste like wheat straw and... more
A study was carried out to determine the effects of organic, inorganic fertilizers and integrated soil fertility management and irrigation levels (1,000, 750 and 500 ml per planting station) on coffee growth. There were no significant... more
El presente documento contiene el Estudio de Factibilidad del Proyecto Producción de Biogás a Partir de los Residuos Orgánicos del Rastro Municipal de Juigalpa, el cual es el resultado del trabajo conjunto realizado entre los... more
Introduction Vermicomposting could increase nutrients availability including phosphorus. During vermicomposting, a decomposition of organic substrates leads to the production of several organic acids, such as malonic, fumaric, succinic... more
Purpose A study was conducted to assess production of Pleurotus columbinus mushroom fruiting bodies for different formulations of rice or corn straw substrates mixed at different percent portions with the corresponding com-posted straw.... more
Background: Vermicomposting is a biological process which may be a future technology for the management of animal excreta. This study was undertaken to produce vermicompost from cow dung and biogas plant slurry under field conditions. To... more
Background: Vermicompost (VC) made from cattle dung as raw material was used as soil supplement in the plots of size 4.5 x 4.5 m. Five treatments were given viz. Soil (control), VC@5 t/ha, VC@10 t/ha, VC@20 t/ha and NPK (recommended by... more
Purpose Catha edulis, commonly called as khat or chat is an evergreen plant cultivated in Ethiopia for its stimulant leaves. The young leaves are chewed as a part of social recreation and the older leaves along with the twigs are... more
Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung : kitchen waste in 30:70... more
Yard waste is either dumped or is being openly burned to get rid of it, instead of using it as a valuable renewable energy source. In this study, hydrothermal carbonization of yard waste was conducted to val-orize it as a solid bio fuel,... more
Recent trend of declining sustainability in agricultural production is appearing as a major threat to most of the Asian countries. To combat the situation, increasing importance is now being paid on incorporation of organic materials for... more
Background: Chicken processing results in the production of a lot of blood which if disposed on land poses environmental hazards in terms of land pollution. The aim of the study was to develop an aerobic composting process for chicken... more
Background Macrophytes (fresh water plants) comprise a diverse group of the flora which play important roles in the maintenance of trophic food chains and biogeochemical processes, but are deleterious when present in excess. However, due... more

Purpose Field experiment was carried out in Akure in the rainforest zone of Nigeria to determine the effect of poultry manure, wood ash and rice bran on the soil fertility improvement, growth and head yield of cabbage (Brassica oleraceae... more
If valorisation strategies are implemented, horse manure is a valuable resource to be used as organic soil amendment and for renewable energy generation. Huge amounts of equine residues are generated in the EU and elsewhere, most of which... more
The potential of pineapple peel as a source of cellulose nanocrystals was evaluated. Peels skin from fresh-cut fruit was used as raw material. These residues were purified to remove pigments, lipids and hemicellulose, and a bleaching... more
Background Organic solid waste management is a major challenge in high population density areas like apartments, educational institutions, hospitals, etc., as their disposal with other wastes could not only lead to issues like vector... more
Purpose The disposal of solid waste is a serious environmental problem for humanity. Vermicomposting is used as one of the methods for recycling of organic waste, resulting in a humified material of great agronomic potential which... more
By using Lumbricus rubellus, vermicomposting started after 3 weeks of pre composting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment... more
Essa pesquisa apresenta uma análise que fizemos de iniciativas para a reciclagem de resíduos orgânicos em duas capitais no Brasil: São Paulo e Florianópolis. Realizamos pesquisa bibliográfica sobre o tema compostagem orgânica e urbana e... more
