Biological Waste Treatment & Investment in Energy from Waste Plant. A Briefing Paper and Consultancy Report for Waste Management Companies

      Аннотация: In pursuit of Scotland's Zero waste initiative and strict compliance with current landfill directives practiced all over Europe, the choice of a suitable biological waste treatment technology for biodegradable wastes becomes a necessity. A combination of Anaerobic Digestion and In-vessel Composting have been proposed after a critical analysis on the said technologies using a multi-criteria decision analysis (MCDA) and several considerations. Thermal hydrolysis has also been recommended as a pre-treatment method based on its compliance with PAS110 and ability to improve the secondary products. Besides the energy generated from the proposed hybrid plan (AD+IVC), novel digestate products - such as concentrated nutrient streams for the production of standardised fertiliser products are also generated. Huge revenues can be generated from these secondary products if properly harnessed and can also cover for the operational cost. Every waste management company looking forward to invest in an energy from waste facility in Scotland, using thermal treatment technology, needs to be fully abreast with the Thermal Treatment of Wastes Guidelines set out by the Scottish Government.
