delivered the opinion of the Court.
This is а dispute between a county, which asserts the power to regulate the disposal of solid waste, and a landowner, which contends that its activities are exempt from regulation because they constitute recycling. Wе conclude that the activities in question are subject to regulation by the county.
The essential facts were stipulated in the trial court. Ticonderoga Farms, Inc. (TFI) operates a 1200-acre farm in Loudoun County upon which it rаises Christmas trees, nursery stock, and pulpwood. The topsoils are thin and contain little organic matter. The subsoil is heavy clay and the land is flat, resulting in poor drainage.
For many years, TFI has engaged in a comprehensive program to improve the land for agriculture. Tree prunings, leaves, brush, stumps, and other organic materials have been systematically collected as they were cleared from TFI’s own lands, and piled in long windrows in order to permit them to decompose. The resulting compost is to be spread over and incorporated into the poorer soils on the farm.
In the spring of 1989, TFI accelerated this program by receiving, for a fee, the sаme kinds of woody waste materials from builders, developers, and others clearing lands elsewhere, and adding those materials to the windrows. In addition, TFI brought in “clean fill” dirt in order to alter the grade of the land in some fields to improvе the drainage.
The windrows of organic material average twelve feet in height. They are periodically turned over and are watered and covered with vines to facilitate decomposition. The materials are never buried or burned, and it is undisputed that they will eventually be converted into agriculturally valuable compost, although it is a matter of conjecture how long it will take the stumps to decompose. All the compost is to bе used on-site, and TFI has not sold *173 or distributed any of it to others. State officials have inspected the composting operations and have found no evidence of any harmful effluent or pollutant. The Loudoun County Fire Marshal has found no fire hazard arising from the composting operations.
In 1978, Loudoun County (the County) adopted an ordinance regulating the collection, storage, and disposal of solid waste, designated Chapter 1080 of the Codified Ordinаnces of Loudoun County (the ordinance). The ordinance required all persons operating facilities for the disposal of solid waste to obtain a permit from the County’s Director of Technical Services as well as a State solid waste disposal permit. The ordinance imposed substantial fees, bond requirements, operational regulations, and construction standards upon the operators of such facilities.
In November 1989, the Lоudoun County Department of Engineering cited TFI for operating a solid waste disposal facility without a permit, in violation of the ordinance, and demanded that TFI cease accepting solid waste from off-site sourcеs. TFI refused the demand and promptly instituted this suit in the trial court against the County and its Director of Engineering. TFI’s bill of complaint prayed for a declaratory judgment and injunctive relief against the enforcement of the ordinance. The County filed an answer and a cross-bill for injunctive relief.
The parties submitted the case to the court on cross-motions for summary judgment and a stipulation of facts. By written opinion, the chancellor ruled that the ordinance was valid, that it applied to TFI’s composting operations, and that TFI was not exempt from its provisions. The court entered a final decree on August 24, 1990, enjoining TFI from the continued receipt of organic waste from off-site sоurces until it obtained all applicable permits pursuant to the ordinance. We granted TFI an appeal. 1
TFI challenges the County’s authority to adopt the ordinance and argues that the court erred in finding that its activities constitute the disposal of solid waste rather than recycling, which is exempt from solid waste regulation. TFI also contends that the court erred in awarding injunctive relief because of the County’s failure to prove irrepаrable harm.
TFI cites the Dillon Rule as we expressed it in
Tabler
v.
Fairfax County,
The chancellor ruled that TFI’s argument was contrary to our holding in
Resource Conservation Mgmt.
v.
Bd. of Sup.,
We also held in
Resource Conservation
that the adoption of the Virginia Waste Management Act did not preempt the field of waste management regulation so as to exclude local involvement in that field. There, we said, “the Act displays legislative intent to permit active local involvement in the field of waste management regulation.”
Id.
at 22,
TFI concedes, as it must, that our holding in
Resource Conservation
would warrant Loudoun County in enacting a total
prohibition
of solid waste disposal activities, but argues that the
regulation
of such activities, which may involve highly technical fine tuning to minimize environmental effects, lies outside the County’s authоrity and resides exclusively with the Virginia Waste Management Board. We do not agree. The power to prohibit includes the power to regulate. Indeed, we have gone so far as to say, “where the power exists to prоhibit the doing of an act altogether, there necessarily follows the power to permit the doing of the act upon any condition, or subject to any regulation, ... as the greater power includes the less.”

v.
Smith,
When the State, in the exercise of its police power, enacts certain regulations, a political subdivision may, if it acts within its delegated powers, legislate on the same subject unless the Gеneral Assembly has expressly preempted the field.
King
v.
County of Arlington,
The chancellor found as a fact that the reception of woody waste from off-site sources constituted the disposal of “solid waste” as defined in Code § 10.1-1400. TFI contеnds that this finding was not supported by the evidence. Rather, TFI argues, its activities actually amount to recycling, which is exempt from the regulations pertaining to the disposal of solid waste. Code §§ 10.1-1408.1(J); 10.1-1414; 15.1-28.01; 15.1-28.03.
TFI’s argument is premised upon the theоry that the statutory definition of “solid waste,” which includes the term “discarded material,” does not apply to TFI’s operations because TFI’s intention is not to abandon or discard the material, but to convert it into compost fоr agricultural use. That argument applies the statutory definition from TFI’s perspective as the recipient of the material. We think the General Assembly intended that the definition be applied from a different perspective. The materials are brought to TFI by developers, builders, and others who have so strong an incentive to discard them that they are willing to pay TFI a fee to receive them. From that perspective, it is difficult to conceive a clearer example of “discarded material.” We hold that the chancellor’s finding was fully supported by the evidence.
Code § 10.1-1408.1(J) (formerly § 10.1-1408.1(H)) provides:
*176 No permit shall be required pursuant to this section for recycling or for temporary storagе incidental to recycling. As used in this subsection “recycling” means any process whereby material which would otherwise be solid waste is used or reused, or prepared for use or reuse, as an ingredient in an industrial process tо make a product, or as an effective substitute for a commercial product.
In our view, the foregoing provision is inapplicable to TFI’s composting activities. There is no immediate use for the waste. No onе can state with assurance how long it will take the stumps to decompose into useful compost. In the meantime, they will lie on the surface of the land as solid waste discarded by developers. At some future time, the stumps and оther waste may become an “effective substitute for a commercial product,” but that expectation is too remote to exempt the composting activities from solid waste regulation in the meantime. They will nеver, according to TFI’s representations, constitute an “ingredient in an industrial process to make a product.” We agree with the chancellor’s conclusion that TFI’s activities are not exempt from regulation as “recycling.”
Finally, TFI contends that the chancellor erred in granting the County injunctive relief in the absence of proof of irreparable harm. TFI points out that the record is devoid of any showing that its composting activities threaten any irreparable injury to the County or to the public.
Although proof of irreparable harm and proof of the lack of an adequate remedy at law are prerequisites to a grant of injunctive relief under a court’s traditional equity jurisdiction, neither showing is required when a statute or ordinance expressly empowers a court to grant injunctive relief against its violation. In that case, “[a] 11 that is required is proof that the statute or regulation has been violated.”
