# Mechanical Separation > Mechanical Separation means the process of dividing a material using techniques, devices, or machines. **Term:** Mechanical Separation **Last updated:** 2026-07-29 ## Definition ## What Mechanical Separation Means in a Contract Mechanical Separation, within a contractual context, describes the use of physical devices, tools, or machines to divide a material into its component parts. This might involve sieving, crushing, magnetic sorting, filtration, or centrifugal separation, depending on the industry and material involved. When a contract references Mechanical Separation, it is usually specifying how a party must process, sort, or extract materials as part of a manufacturing step, waste management obligation, or supply chain requirement. The term is distinguished from chemical separation, thermal separation, or manual sorting because it relies purely on mechanical force or physical properties such as size, density, or magnetism. Contracts that reference this process often do so to set a technical standard that must be met, whether for quality assurance, regulatory compliance, or cost allocation between parties. Understanding the term matters because it defines both the method and, indirectly, the expected outcome. A party agreeing to perform Mechanical Separation is agreeing to a specific technical approach, not simply an end result, which can affect liability if the separation is later found to be inadequate. ## How Mechanical Separation Is Defined or Measured Because Mechanical Separation is a technical process, contracts typically define it by reference to the equipment used, the separation efficiency required, or an applicable industry standard. For example, a supply agreement might specify a minimum purity percentage achievable through mechanical means, or require that separated materials meet a defined particle size range. Measurement can also involve third-party verification, such as inspection reports or laboratory testing confirming that mechanical processes achieved the agreed separation threshold. In some agreements, the parties incorporate a
