Resumen:
Una pyme británica ha desarrollado un nuevo proceso para obtener productos de valor a partir de residuos sólidos urbanos mediante la recuperación de pulpa de celulosa y materiales reciclables. La pulpa puede utilizarse como un producto de fibra y convertirse en azúcares que se fermentan en biocombustibles celulósicos o se convierten en otros productos de alto valor. El proceso utiliza una planta de digestión anaerobia en fase líquida de alta eficiencia para generar biogás. La empresa busca socios con el fin de establecer acuerdos de comercialización y cooperación técnica para crear oportunidades de mercado.

Tittle:
Waste to biofuel technology offers zero waste and value extraction solution for municipal solid waste processors
Summary:
A UK based SME has a new process which derives value -Y- products from residual Municipal Solid Waste by recovering cellulose pulp -Y- recyclable materials. The pulp can be used as a fibre product, converted to commodity sugars which can be fermented into cellulosic biofuels or converted to other high value products. The process utilises a highly efficient liquid phase Anaerobic Digestion (AD) plant to generate bio-gas. Commercial -Y- Technical agreements are sought to develop market opportunities.
Description:
The UK based SME has an innovative ´waste´ recovery process which generates biogas, clean sugars and recyclable materials from Municipal Solid Waste (MSW). The process is designed to recover and recycle materials from the residual waste stream diverting them from landfill and providing associated environmental and economic benefits.
The company has developed a solution which supports the move towards a circular economy through the continual circulation of resources. The process involves pulping and washing residual MSW to recover cellulose, producing biogas (bio-methane) and dry recyclables such as rigid plastics and metals.
The washing stage of the process produces a clean, activated cellulose substrate which can either be sold as a fibre product or converted to commodity sugar via enzyme hydrolysis. The sugar can be used as a platform chemical for other markets such as fermentation to bio-ethanol.
The washwater, which is rich in soluble organics feeds a high-rate liquid phase anaerobic digestion (AD) plant which produces a high concentration (>70%w/w Methane) bio-gas without digestate production, thus removing a significant disposal issue for conventional AD/MBT (Anaerobic Digestion/Mechanical Biological Treatment) operations.
Any recyclates (metals and rigid plastics) are removed from the process for recycling.
The company is currently engaged in a high-level feasibility project to develop the process beyond demonstration stage. A small-scale pilot plant is being established in the UK to demonstrate the process and undertake further optimisation activities.
The company is interested in hearing from potential partners for R-Y-D collaboration projects for process optimisation, commercialisation and end user/market applications.
Advantages and Innovations:
There are a number of advantages and innovations which are inherent in the process.
- The process fits within the existing waste collection and treatment infrastructure as it is designed to take residual waste. It is also possible to process Material Recovery Facility (MRF) rejects or compost-like output (CLO) from Mechanical Biological Treatment (MBT) plants.
- The recyclates recovered from the process have been cleaned in the washing plant so these products are relatively free of contamination and suitable for reprocessing.
- The process also generates heat so that the recyclates can be dried.
- The use of the liquid phase AD plant significantly reduces residence time, consequently reducing capital costs.
- The process recovers materials previously destined for landfill, which could increase recycling rates by 10 - 15% (depending on the composition of the inlet material).
- The variety of end products generated means that the process is less vulnerable to market fluctuations.
- The sugar produced can displace food grade sugar in certain applications, with associated environmental and social benefits.
- Fermenting the sugar to ethanol is a low temperature process, providing a low operating cost business model.

Partner sought

Type and Role of Partner Sought:
Partners are sought to facilitate the commercialisation of demonstrator plants and the development of commercial opportunities across the MSW value chain.
This could be down-stream to resource distributors, material converters/re-processors or end users (of fibre products, commodity sugars, cellulosic biofuels -Y- recyclate), Also up-stream stakeholders such as public sector/local authorities and pre-processors.
