with considering importance of post harvest operation on quality criteria of pot marigold (calendula offıcinalis l.), the effect of flower nutrient source (organic inputs such as cattle manure (25 t ha-1), municipal waste compost (20 t ha-1), spent mushroom compost (15 t ha-1), vermicompost (15 t ha-1) and control) as well as different drying methods including microwave (300, 600 and 900 w), ov...

this fertility experiment was carried out using split plots based on a randomized complete block design of three replications in 2006 at sari agricultural sciences and natural resources university. the aim of the experiment was to investigate some macronutrient and micronutrient accumulation in leaves of different soybean cultivars as influenced by some organic fertilizer types and levels. main...

In 1993, the Georgia Diagnostic and Classification Prison (located near Jackson, GA) initiated an on-site composting operation to convert food waste into a useable by-product. Each week, inmates compost about 20 tons of food waste, which are mixed with ground cardboard, hay, yard leaves, or wood products. The operation takes place on a 1.2-ha site (3 acres) that drains towards a small, paermial...

Agricultural operations generate large quantities of manure which must be eliminated in a manner that is consistent with public health guidelines. Meanwhile, construction and demolition waste makes up about 25% of total solid municipal waste. Co-composting of manure with construction and demolition waste offers a potential means to make manure safe for soil amendment and also divert constructio...

In a column experiment with horizontal permeable barriers, the effects of a biodegradable chelator-nitrilotriacetic acid (NTA) on the uptake of heavy metals from municipal solid waste (MSW) compost by Festuca arundinacea and metal leaching were investigated. The use of NTA was effective in increasing Cu, Pb, and Zn uptakes in shoots of two crops of F. arundinacea. In columns with barriers and t...

This study examined macro-nutrient content of solid waste compost to determine the potential of the compost for soil fertility amelioration in Ghana. Heavy metal concentrations in the compost were also examined to assess the potential health implication of compost application in urban and peri-urban agriculture. It was observed that the overall NPK concentration was low in the different compost...

Effects of yard waste compost and maize (Zea mays) cultivar on population densities of plant-parasitic nematodes were examined in four experiments in north Florida. In one experiment, eight maize cultivars were evaluated; the other three experiments involved split-plot designs with compost treatments as main plots and maize cultivars as subplots. The three compost treatments used in these exper...

Rapid urbanization and industrialization, population growth and economic growth in developing countries make management of municipal solid waste more complex comparing with developed countries. Furthermore, the conventional municipal solid waste management approach often is reductionists, not tailored to handle complexity. Therefore, the need to a comprehensive and multi-disciplinary approach r...

Taiwan’s Environmental Protection Administration (EPA) has enacted a food waste recycling policy since 2003 as an alternative of landfill and incineration for the final disposal of municipal solid waste. Recycled food waste is currently seen as a valuable material, especially when appropriate technology is developed. This paper conducts a cost/benefit analysis based on six cases of food waste c...
