_A full material profile per stream — identity, soil determination, regulatory status, composition, properties — that prints as the document a generator signs._ # The profile is the document a facility approves. A material profile data sheet per stream, kept as a record rather than a PDF in a folder — and started, for commercial clients, by the person who knows the material. _Screen: a material profile data sheet (MPDS) — regulatory status, soil determination, chemical composition and physical properties; prints as the document a generator signs._ - **What it carries.** Identity, the soil determination with its analytical tests, regulatory status (RCRA and DOT), chemical composition with constituent ranges, physical properties, and the certification. - **It prints and it signs.** The sheet prints as the document a generator signs and a facility files, and downloads as PDF. A client's whole profile book comes out as one PDF. - **No profile, no quote.** A C&I quote line naming a waste with no profile on file cannot be sent — the facility has nothing to approve. The screen says so in words. - **Started in the portal.** A commercial client fills in the profile for what it generates from its own login. The characterization starts with the person who knows the material and arrives with the service request. ## A profile on screen. Regulatory status, soil determination, chemical composition — the fields a facility reviews, kept on the stream's record and printed when a signature is needed. _Screen: a material profile data sheet (MPDS) — regulatory status, soil determination, chemical composition and physical properties; prints as the document a generator signs._ ## Questions ### What is a material profile data sheet? The characterization document for a waste stream — identity, composition, physical properties, regulatory status and the soil determination with its analytical tests — which a [designated facility](/glossary#designated-facility) reviews before it will accept the stream. In Mercovi it is a record that prints as the document the generator signs and the facility files. See the [glossary](/glossary#mpds). ### Can a client fill in its own profile? Yes. A commercial client starts the material profile from its own login in the portal — identity, composition, physical properties, regulatory status — with its own knowledge of the material. The submission arrives with the service request and walks into a quote to be priced once the profile is complete; until then the quote says, in words, what is missing. The eight records: [Clients and sites](/platform/clients-sites) · [Waste catalog](/platform/waste-catalog) · [Waste profiles](/platform/profiles) · [Manifests](/platform/manifests) · [Crew](/platform/crew) · [Billing](/platform/billing) · [Reports](/platform/reports) · [Configuration](/platform/configuration) - ‹ Previous — **Waste catalog** The catalog is where a waste is described once — its shipping description, its codes, where it goes and what it costs per measure — and then used by every line. [Waste catalog](/platform/waste-catalog) - Next › — **Manifests** Any RCRA code on a waste makes it a Uniform Hazardous Waste Manifest. Nobody picks the form from a dropdown, and the manifest tracking number lands back on the job. [Manifests](/platform/manifests) ## See it run a job end to end.
