UK-Mexico Project

— ObjecCves: Develop integrated processes for high-efficiency and flexible

uClisaCon of lignocellulose to produce biofuels and added-value products.

— Scopes: aviaCon fuel producCon, lignin valorisaCon, chemical producCon,

biomass supply chain modelling

— Focused on Mexico local agricultural residues (e.g. sugarcane bagasse,

agave bagasse)

Microbial Fuel Cell (MFC) Electricity genera>on Microbial Electrosynthesis Cell (MEC) Product genera>on

• Examining the economic performance and environmental impacts of copper

recovery from disCllery wastewater using MFC/MEC systems.

• SensiCvity analysis of MFC and MEC parameters on LCA.

Waste Management Project

• 4. Mul>-parametric Assessment of Policies for Resource

Recovery from Waste (MAPeRR), 2016-2017

Ash disposal and nutrient recovery Digestate disposal & nutrient recovery Mineral extrac>on & nutrient produc>on Agriculture and food produc>on Thermal & biological energy recovery

Scopes

— Phase 1: Reviewing key policies and regulaCons relevant

to organic waste management

Ø SWOT analysis

— Phase 2: QualitaCve and quanCtaCve analyses of impact

associated with resource recovery from organic waste management system

Ø PESTEL (poliCcal, environmental, social, technological,

economic and legal)

Ø LCA

17

Summary

Success in resource recovery and waste management projects requires:

— MulCdisciplinary research approach — Experience sharing and learning through internaConal

collaboraCon

— Applying systems approach and enhancing exisCng

methodology (e.g. to include policy and social assessment).
