    摘要: A method of incorporating a peroxide source that produces reactive oxygen species and optionally also incorporating steam with the peroxide source (or other source of heat), into soil as a method of soil remediation, i.e., to destroy or remove chemical contaminants that pose a threat to plant or animal life. The invention also relates to the use of the peroxide source along with optional steam (or other heat source) or hot vaporized peroxide solution to treat soils, in particular those intended for agriculture, as a pesticide for controlling nematodes, pathogenic fungi, insect pests and bacteria. The peroxide source may be applied to the soil using soil cultivation equipment to increase contact between the peroxide source and the soil to be treated. The peroxide source and/or steam or other source of heat or hot vaporized peroxide solution can also be applied with injection wells or infiltration galleries, for instance, for the pesticide use and soil remediation.

    摘要: One or more techniques and/or systems are disclosed for a bio-derived, environmentally friendly soil conditioner to facilitate the removal of overburden (also known as spoil) in tunneling and mining operations. The bio-derived, biodegradable, and non-toxic formula may be injectable into the soil-cutter interface, and can thicken the tunnel water and disperse the soil to improve the removal of the spoil. The biodegradable soil conditioner may comprise: 1) about 45% to about 75% triglyceride oil by weight; 2) about 20% to about 50% super absorbent polymer by weight; and 3) about 1% to about 4% surfactant by weight. Further, the biodegradable soil conditioner may comprise about 0.1% to about 1.0% viscosity thickening agent.
