Leaf protein concentrate from paunch grass and green waste: A technoeconomic analysis and lifecycle assessment
… from negative value paunch grass (PG) and leafy green waste (GW). The chemical compositions PG and GW have therefore been determined for the first time in New Zealand. Their protein contents (15.2 to 16.2 DM%) are comparable to those of alfalfa and ryegrass, making them suitable LPC feedstocks. …

Composted green material and its use in growing media
… this research was to establish various trends in green waste production for example variation in source and treatment of green waste. A comprehensive overview of the current green waste cycle was undertaken via a questionnaire titled 'Management of Green Waste'. From the producers of composted …

The use of organic materials as amendments in the remediation of soils contaminated by lead, copper and zinc
… experiments in contaminated media, and greenhouse pot experiments. Batch sorption studies were conducted to evaluate the ability of bone meal, composts, peat, coir and wood bark to sorb Pb, Cu and Zn. Single sorption carried out over a metal concentration range of 0.1 mmol 1-1 using …

COMPOST QUALITY RECOMMENDATIONS FOR REMEDIATING URBAN SOILS
… We found composts made from food scraps or leafy green waste provided sufficient nutrients for plant growth without excess nutrient loss. Using our findings along with those found in the literature, we provided ranges of compost characteristics to inform the selection of compost for on-site soil …

Implementation of Sustainable Management Practices at Two California Central Coast Vineyards and Their Effects on Soil Fertility
… All.], and zorro annual fescue [Vulpia mourns]), green waste compost (Forest Blend), and reduced tillage on soil fertility were investigated in San Luis Obispo, California on a clay and sandy loam soil. Between the fall 2007 and spring 2008, which had a low precipitation amount (13.3 & 15.6 …

Carbon in urban, brownfield and heavy metal contaminated soils
… fluxes were enhanced by adding a small amount of green waste compost to these soils but large applications did not greatly increase carbon storage further. Enhanced losses of carbon by dissolved organic carbon leaching and increased soil respiration rates were consequences of greenwaste compost …

Optimisation of anaerobic digestion of organic solid waste for the production of quality compost for soil amendment
Organic Fractions of Municipal Solid waste (OFMSW) is rich in organic matter, which can be recycled through energy recovery and compost production. The move towards sustainable management of OFMSW is shifting from energy recovery alone to the integration of separation at source, feedstock selection …
