Particulate compositions are described comprising an intimate mixture of a biomass char producedfrom the combustion of a biomass, such as switchgrass or hybrid poplar, with at least a second carbonaceous material, such as petroleum coke or coal, and, optionally a gasification catalyst, for gasification in the presence of steam to yield a plurality of gases including methane and at least one or ...Highlights Two copper mine soils were treated by planting trees and amending with wastes. The physical degradation of the untreated soils was considerable. The planted trees increased soil porosity in the mine soils. The added wastes increased MWD, WSA and SI due to their organic C content. To use both treatments is the best to improve the soil physical situation.
