The UrbanGold technologies are solutions for proper metallurgical treatment of all non-ferrous qualities of e-waste – including the lowest grades. Core of our technology is a flexible and customer tailored metallurgy with optimized slag chemistry and most modern environmental protection. We combine the advantages of both pyrometallurgical and hydrometallurgical processes while minimizing the disadvantages of each. Our portfolio includes the newly developed HENRI smelter as well as the TBRC technology, depending on raw material mix and boundary conditions. Targets are a maximized metals yield, as well as a best possible utilization of e-waste – to make e-waste recycling both a profitable and sustainable business.

UrbanGold’s core competence is the development and design of recycling processes for the metals industry. The focus is on complex, non-ferrous secondary raw materials and materials that pose a major challenge for established standard processes. • Technical and economic feasibilty Due to its many years of experience, UrbanGold can very quickly carry out a basic technical feasibility analysis and a rough economic assessment for a wide range of problems. All relevant, environmentally specific issues are considered. • Process development If the first technical and economic feasibility leads to a promising result, UrbanGold develops the recycling process step by step until the technology is ready for investment. • Process modeling Every process development at UrbanGold is accompanied by process modelling, and mass & energy balancing, respectively. This enables tailor-made solutions and is the basis for plant engineering. • Process engineering By process engineering we mean a detailed elaboration of the individual process stages, each with individual mass & energy balancing, the description of critical process parameters, relevant influencing factors, a meaningful illustration of the process flows and much more. • Implementation Together with our partners, we also offer further engineering packages and plant deliveries.

UrbanGold offers customised consulting services in the metallurgical recycling industry. • Fitness check Where do they stand compared to the best in the industry. • Recycling Process Optimization From modelling and creation of a digital twin to parameter studies and on-site optimisations • Metallurgical consulting & coaching We develop measures for process optimisation and offer customised training for your employees • Studies Tell us your challenge - we will find the right solution.

UrbanGold has all the knowledge required for the proof of feasibility, the creation of a technical concept, the consideration of legal aspects and environmental protection, and the realization of the project on behalf of the project owner. What is more, we are also your partner for commissioning, start-up, training, and long-term operation – including further optimization for continuous improvement of the economic success. • Planning phase Planning a metallurgical recycling plant is the pinnacle of project development. Expertise in a wide range of complex technical topics is required, as well as profound knowledge of the business model of smelting and refining valuable metallic and complex raw materials. In addition, environmental protection and sustainable operation are of great importance and can have a significant impact on the business case. • Interface management In complex processes with different plants and partners, interfaces are of crucial importance. UrbanGold is happy to support here with its experience and thus makes a decisive contribution to ensuring that implementation runs smoothly. • Technical consulting UrbanGold supports the project management during the entire project realization, of course technically and metallurgically, but also in all areas that are not directly related to the recycling process – such as environmental issues, permitting processes and the infrastructure area. • Support during plant ramp-up During commissioning, we ensure that no technical question remains unanswered, and we support the ramp-up to the contractually agreed conditions. • Continuous improvement The operation of a recycling plant is subject to constant changes in the boundary conditions. Be it a changing raw material, the growing demand for product quality or simply the desire for a successive expansion of the processing capacity. We see ourselves as a partner beyond commissioning and provide support for all future challenges.
