Sustainability-inspired composting latrine design
In support of the Millennium Development Goals to provide improved sanitation to the world, a sustainability-inspired composting latrine design based on work in rural Panama, but also applicable to similar situations, is offered here. The design is based on the three aspects of sustainability namely economic, social, and technical. The new design will allow for improved health for current and ...

Composting of washed Ulva reticulata seaweed: process parameter variations and compost quality
Co–composting process of unwashed (Run A) and washed (Run B) seaweed Ulva reticulata with bagasse and broiler litter was studied. Peak temperatures of 48.9°C and 55.2°C were recorded for Runs A and B, respectively. For Run A, the starting wet bulk density was 43.31 kgm–3 and increased by 5.2 times on day 23. Net biodegradable Volatile Solid (VS) reductions were 2.19 and 11.44% for Runs A and B, ...

Kinetic study of compost liquor nitrification
This study is a first kinetic approach about the compost liquor treatment by activated sludge. This industrial wastewater is highly loaded in organic and nitrogen compounds (COD≈12,000 mg L−1 and NH4+-N≈4,000 mg L−1). The possibility of its treatment in an urban WWTP is studied measuring ammonia oxidation rate with non-acclimated sludge to the industrial effluent. Compost liquor appears as an ...

Sludge composting, sludge pretreatment and radiation technology: a review
The paper reviews the state-of-the-art technologies on sludge conditioning and stabilisation. Radiation technology, best contextualised within the concept of Green Chemistry, is yet another developing area of sludge pretreatment. Besides revisiting some important aspects of sludge treatment by composting, this review paper also appraises the application of gamma ray and ultrasound irradiations ...

Use of manure, compost, and cover crops to supplant crop residue carbon in corn stover removed cropping systems
The emerging cellulosic-based ethanol industry will likely use corn (Zea mays L.) stover as a feedstock source. Growers wishing to maintain, or increase soil C levels for agronomic and environmental benefit will need to use C amendments such as manure, compost, or cover crops, to replace C removed with the corn stover. The objective of this research was to determine the effect of cover crops, ...

Dairy manure compost effects on corn silage production and soil properties
Accumulation of dairy manure compost has created a need to identify alternative uses for this plant nutrient source. This field study determined compost effects on corn (Zea mays L.) silage production, nutritive value, and soil characteristics for three growing seasons following incorporation of dairy manure compost at 0, 35, 70, and 105 Mg dry matter (DM) ha–1. Yields from subplots receiving ...

The state of composting and biological waste treatment in the UK
In 2005/06 3.4 million tonnes of source segregated waste was composted, an increase of 28% on the previous year. 85% was municipal waste, with just over half of this collected at civic amenity sites Less than one per cent of municipal waste was kitchen waste collected at the kerbside 65% of waste composted was composted at dedicated composting / biological treatment sites, with 10% on farm ...

Commercial composting provides food for thought
The retail sector and food manufacturers produce a mountain of waste but, unlike householders, they cannot simply throw it in the compost and wait for it to rot down. The Compost Association told edie about the obstacles in the way of recycling waste from the commercial sector. Compared to household domestic waste, biodegradable matter from the retail and catering sector represents only a small ...

Quality of compost: the experience of veneto region
The Regional Administration of Veneto Region (Italy) established in 1991 the rules for authorisation of composting plants for treatment of pre-selected organic wastes, including urban sludges, organic fraction of municipal solid wastes and animal manure. Also chemical composition of compost were regulated (Table 1). Some composting plants started working in 1994; at the moment seven farms are ...

Composed based growing and potting media source Material - Production - Market - Utilisation – Use
The increasing biological waste treatment (composting) in Germany provides now and in future sufficient quantities of composts for the most different markets. However a closed loop management is only sensible if the produced composts can be utilised in a profitable manner. For the time being the Stender GmbH, as a manufacturer of growing media, is exclusively interested in growing media quality ...
