# Glossary

The words Circular OS and this Help Center use, from AVV code to weighing slip, each with a short definition, its German name and the guides that explain it.

Each term has its own link: copy it from the term to point a colleague, or an AI tool, at one definition. The German name is listed under every term, so you can match the English app to the German one.

- **AI Upload** (DE: KI-Upload): The part of Circular OS that reads your invoices, weighing slips and delivery slips and turns them into orders. Uploads, and documents sent to your processing email address, arrive as batches for you to review. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/), [Upload a delivery slip](https://portal.staging.resourcify.com/help/documents/upload-a-delivery-slip/).
- **Auto-approve** (DE: Automatische Genehmigung): AI Upload imports a recycler's documents without your review once you have approved three of its batches without a fix. Anything doubtful is held back in its own batch, with the reason. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **AVV code** (DE: AVV-Schlüssel; waste code; EWC code): The six-digit waste code from the German waste catalogue (Abfallverzeichnis-Verordnung), written in pairs such as 17 04 05. Every waste type carries one, and Circular OS fills in the hazardous flag from it. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **Batch** (DE: Charge): A set of documents uploaded together, or sent to your processing email address together, that AI Upload reads and you review and approve as one. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **Cancellation invoice** (DE: Stornorechnung): An invoice that cancels an earlier one. AI Upload cancels the order it names, also against a credit note, and labels it as a cancellation.
- **Collection** (DE: Abholung; pickup): The pickup of waste from one of your locations on a given day, the most common kind of order. The Orders list shows every collection, newest first. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/).
- **Container type** (DE: Behältertyp; container): The kind and size of container a waste is collected in, such as a 1.1 m³ bin or a 40 m³ roll-off container. Container types are master data under Settings, and AI Upload reads them from your documents.
- **Cost per Location** (DE: Kosten pro Standort): The table in the Cost Report that shows what each location spends on each waste type, with the all-in cost per tonne and the orders behind every figure. See: [Read the Cost per Location report](https://portal.staging.resourcify.com/help/reporting/read-the-cost-per-location-report/).
- **Credit note** (DE: Gutschrift): A document in which the service provider pays you instead of invoicing you, usually for valuable material such as metal scrap. Credit notes can follow a price index.
- **Delivery slip** (DE: Lieferschein; delivery note): The document handed over at a collection that says what was collected, from where and how much. Uploaded to an order, it is read and kept as proof with the record. See: [Upload a delivery slip](https://portal.staging.resourcify.com/help/documents/upload-a-delivery-slip/).
- **Density factor** (DE: Dichtefaktor; density): The weight of one cubic metre of a material in a container. With a density on the waste type, Circular OS estimates the weight of a collection that was not weighed. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/).
- **Estimated weight** (DE: Geschätztes Gewicht): A weight worked out from the container and the material's density factor when no one weighed the collection. Totals that include an estimate are marked, and hovering the marker shows how much is estimated. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/).
- **Location** (DE: Standort; site): One of your sites where waste is collected. Orders, costs and reports are grouped by location, and duplicate locations can be merged in Settings. See: [Read the Cost per Location report](https://portal.staging.resourcify.com/help/reporting/read-the-cost-per-location-report/).
- **Order** (DE: Auftrag; service order): One service for one of your locations: a collection, a transport or a container rental, with its lines, weights, costs and documents. Every figure in a report leads back to orders. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/), [Getting started](https://portal.staging.resourcify.com/help/start/getting-started/).
- **Price index** (DE: Preisindex; index price): A market index a contract price can be linked to. Credit notes then follow the index's monthly value without anyone changing the price by hand.
- **Processing email address** (DE: Verarbeitungs-E-Mail-Adresse): Your organisation's own address for documents. Everything sent to it arrives in AI Upload as a batch, the same as an upload. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **Reading rule** (DE: Regel; AI rule): A correction you save in AI Upload as a sentence, such as reading “Mixed scrap” from one recycler as steel scrap. The file is read again with it, and so is every later document from that recycler. Rules stay within your organisation. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **Recycler** (DE: Entsorger; disposer): The service provider that takes your waste and recycles or disposes of it, and whose weighing slips and invoices AI Upload reads. In the app, recyclers are listed with the service providers. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
- **Recycling rate** (DE: Recyclingquote): The share of your waste that is recycled, as your organisation defines it: recycling only, recycling and recovery, or everything diverted from landfill.
- **Role group** (DE: Rollengruppe): The kind of access a team has in Circular OS, for example insights only or running operations. Release notes in What's new are shown to the role groups they apply to.
- **Separation rate** (DE: Getrenntsammlungsquote): The share of your waste collected as separated streams rather than as mixed waste. It is the inverse of the mixed waste rate and shows on the Home dashboard.
- **Service provider** (DE: Dienstleister; supplier): A company that carries out services for you: collecting, transporting, recycling or disposing of waste. Service providers and their locations are master data under Settings. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/).
- **Surcharge** (DE: Zuschlag): An extra charge on an order on top of the service, reported by type: CO2 surcharge, energy surcharge, toll and other surcharge. See: [Read the Cost per Location report](https://portal.staging.resourcify.com/help/reporting/read-the-cost-per-location-report/).
- **Tenant** (DE: Mandant; organisation account): Your organisation's own space in Circular OS, with its data, users, settings and reading rules. You log in to your tenant, and nothing in it is visible to other customers. See: [Getting started](https://portal.staging.resourcify.com/help/start/getting-started/).
- **Waste balance** (DE: Abfallbilanz): The yearly summary of the waste each site produced. Circular OS exports it per site as a spreadsheet for the authority report.
- **Waste type** (DE: Abfallart; material; waste material): A material you dispose of, such as steel scrap or paper and cardboard, with its AVV code, hazardous flag and density. Waste types are master data under Settings, and duplicates can be merged. See: [Find and filter your orders](https://portal.staging.resourcify.com/help/orders/find-and-filter-your-orders/).
- **Weighing slip** (DE: Wiegeschein; weighbridge ticket): The record from the weighbridge with the weight of a collection. AI Upload reads it, and the weight shows on the order as weighed. See: [Review an AI Upload batch](https://portal.staging.resourcify.com/help/documents/review-an-ai-upload-batch/).
