empto is a platform that brings together waste-disposal firms and business operators. It provides each of them with a platform on which waste-disposal orders can be transacted quicker, more simply, and with more transparency.

As a digital assistant for waste disposal, empto enables waste-disposal firms and business operators to take the disposing of waste materials into their own hands – over 16 different kinds of waste including building debris, bulky waste, restaurant waste, or green waste. The communication and the order transaction are simple and digital. With only a few clicks, you as a business operator determine which kind of waste material has to be disposed of, where the container is to be delivered, and whether it is a single order or a recurring order. After placing your order, you will then receive individual offers from different waste-disposal firms. From these you can choose the offer that is best for you. Order status, certificates, invoices, credited amounts, and verifications of performance are accessible on the platform at any time – whether from somewhere on the road or from the office.

The integrated empto Waste Manager allows you to not only manage the orders placed via the platform but the management of external processes as well – free of charge. empto answers questions, reviews verifications, generates invoices, and carries out payment procedures – while you always have everything in view.

To ensure the fairest prices for you at all times, our platform is designed in a way that prevents the waste-disposal firms from seeing the offers made by the other firms. You of course can see all the offers, including ratings and prices – utmost transparency from which you profit.

Everything can be managed digitally via empto – which saves you not only time but valuable resources as well.
