GreenE Waste To Energy S.L. (GreenE), from Alicante Spain, is one of the latest companies to implement CADMATIC software. GreenE’s mission is to design, build, set up, commission and promote turnkey waste-to-energy power plants. The plants recover energy from waste, among others, from municipal solid waste (MSW), biomass, and end-of-life tires (ELTs), also known as waste or scrap tires. Sustainability and environmental friendliness are values that GreenE share with CADMATIC. We are proud that GreenE has chosen CADMATIC for the design of these highly complex and environmentally friendly plants.
What sets GreenE apart from its competitors is the innovative technological process it has developed for the implementation of energy recovery plants. The company’s gasifiers produce high quality syngas suitable for combustion in alternative CHP engines. The syngas is also transformed into thermal heat and electrical power.
Gasification is preferable to incineration as it uses much less oxygen in the process. Just 25–30% of oxygen is required to complete the combustion of organic matter and, as such, comes with clear environmental benefits.
GreenE’s solutions are suitable for a wide range of waste types, but it has developed special expertise in three core know-how areas: biomass to energy, municipal waste to energy, and end-of-life tires to energy.
Turning waste into energy
GreenE sets up state-of-the-art plants for the generation of renewable energy from biomass gasification. This is a business area in which it has set the benchmark thanks to its cutting-edge technology. The biomass processed includes, e.g. pine chips, pine pellets, olive pomace, beech chips, sawmill waste, and rice husk pellets. In the area of municipal waste, GreenE designs plants that not only recover energy from the reject fractions of waste, but also manage waste reception, waste sorting, organic matter treatment, and gasification. Despite the rapid growth in recycling, a large amount of waste still finds its way to landfills. In order to mitigate the problem, sorting centers are required where recyclable materials (e.g. plastics, paper and cardboard) can be sorted, the resulting organic matter dried or composted, and energy recovered from the reject fraction. GreenE’s designs and implementations cover the entire chain from municipal waste to energy. Tire waste is a massive global problem due to its non-biodegradability, flammability and hazardous chemical composition. According to Wikipedia, 450 million ELTs are generated annually in the U.S. alone. Figures indicate that more than 80% of tires are simply disposed of in landfills. GreenE has developed high quality and environmentally friendly processes used to gasify old tires, thereby solving a waste problem and also generating much needed energy. The company’s management plan for this type of waste consists of controlled storage, shredding and processing, recycling, and energy recovery.
Highly complex plants require a complete software solution
The gasification plants designed and built by GreenE are highly complex. They make use of between 1,000 and 5,000 kg/h of raw materials and produce up to 6 MW electrical power. The plants commonly have up to 700 sensors and different pieces of equipment. According to GreenE Product Development Manager, Vicente Centelles Chuliá, the complexity of the gasification plants requires the use of a comprehensive software package. He has been at GreenE for three years and is responsible for the design of plants and the innovation and design of new processes and reactors. “In the past we used Draftsight® and Solidworks® together with a custom database to create both the P&IDs and layouts. The problem with this solution was that the P&IDs and the layout were not connected. We decided to implement CADMATIC when we realized that we needed a more complete solution to handle the complexity of our plants. With CADMATIC we have a solution that connects the 2D, 3D and the database. This has been a key factor in helping us to reduce errors,” says Mr. Centelles Chuliá.
Pilot plant project designed with CADMATIC
The GreenE design team is currently using CADMATIC Diagram and Plant Modeler for the design of a 50–100 kg/h pilot plant both for biomass and sludge gasification, which will also be used in tests for solid urban waste gasification. The pilot plant project will be completed in June of 2018.
Reduction in errors
GreenE has been using CADMATIC for some months now, but some of the software benefits are already clear in Mr Centelles Chuliá’s mind. “The use of CADMATIC has improved the collaboration between the different members of our team and has also reduced the number of errors that are made. Fewer errors not only mean better quality, but also save time, which will assist us to complete projects on tighter schedules.”
