Two I 100-Lprimary-secondary sludge (3:I by volume) samples from an RMp/ci1/Ip newspl-int mill were composted for six weeks using a static pile, forced-aerationprocess in insulated reactors with different control regimes. The raw sludge was nonhazardous and was easily composted without a bulking agent or urea amendment. Composting rate was unaffected by mokture content over the range investigated Little change in m a s or volume was observed except for water loss. The six-week-oldcomposts produced in the two reactors were similar, with physical and chemical properties suitable for plant growth. Germination of lettuce seed was similar in extracts from both composts and from peat moss. The growth of tomato plants in soilless media amended with six-week-oldcomposted sludge was comparable with growth in a peat-moss-amended medium. Two variables- cation-exchange capacity and total humus content-were strongly correlated with compost age andplant growth. Thk suggests that these twopkysical properties could be used aspredictors of compost maturity in an industrial compost facility. |
