Grimes SM, Tanpoonkiat W, 2013, Thailand: Steps towards integrated solid waste management, Proceedings of Institution of Civil Engineers: Waste and Resource Management, Vol: 166, Pages: 167-176, ISSN: 1747-6526
The current waste management practices in Thailand have been analysed to identify changes that would be beneficial in achieving the criteria set by authorities for improvements in recycling and diversion from landfill to 2030. The numbers and combinations of selected treatment plants that would have to be introduced into Thailand to meet targets for diversion of biological waste from landfill and the production of energy over the planning period have been calculated for a number of scenarios. Sensitivity analyses are performed on the results obtained to account for changes in future assumptions on the amount of waste generated and the organic content of the residual waste. The methodology adopted in this work, to aid planning decisions on technology requirements into the future, was previously used to predict the treatment options for handling the organic fraction of waste generated in London. As a generic methodology, applied in this work to illustrate the types of results obtained from the analyses using specific sets of assumptions relevant to Thailand, it offers the capability and flexibility to take account of the effects on the outcome of any relevant scenarios that planners might wish to consider and any assumptions that they might wish to make.

Abbe OE, Grimes SM, Fowler GD, 2011, Decision support for the management of oil well drill cuttings, Proceedings of Institution of Civil Engineers: Waste and Resource Management, Vol: 164, Pages: 213-220, ISSN: 1747-6526
Depending on the hole size and mud type used in the drilling process, oil well drill cuttings can be a relatively high-volume solid waste stream from drilling operations in the oil and gas exploration and production industry. Current management practices tend to involve thermal treatment followed by landfill disposal. The waste-to-resource conversion approach, however, provides opportunities that are not reflected in the current management system. The drill cuttings waste management decision support tool described in this work allows for the consideration of alternative reuse applications such as in construction materials, oil well reinjection, wetlands restoration, and the manufacture of stable leach-resistant material such as glass ceramics, in a move to divert treated drill cuttings from landfill towards zero waste disposal.

BACKGROUND: The production of paper makes use of cellulose and lignin as a rawmaterial, and almost all cellulose and ligninproduction comes from raw wood materials, contributing to deforestation and resulting in potential environmental harm. It istherefore beneficial to develop technologies for cellulose and lignin recovery for re-use and sustainability of resources.RESULTS: Three imidazolium based ionic liquids (ILs), 1-(2-cyanoethyl)-3-methylimidazolium bromide (cyanoMIMBr), 1-propyl-3-methylimidazolium bromide (propylMIMBr) and 1-butyl-3-methylimidazolium chloride (butylMIMCl), were synthesised bymicrowave technology and fully characterised bymass spectrometry, thermogravimetric differential scanning calorimetry, thinlayer chromatography, nuclear magnetic resonance and Fourier transform infrared spectroscopies. Cellulose and lignin weresoluble in all three ILs with solubility being greatest in cyanoMIMBr. Regeneration of cellulose and lignin was achieved fromsaturated solutions of cellulose in IL and lignin in IL for all three ILs. The ILs propylMIMBr and butylMIMBr have been used forthe first time in the separation and recovery of cellulose and lignin and regeneration of the IL from a mixture of cellulose andlignin in IL. FTIR analysis confirms successful recovery.CONCLUSIONS: This work demonstrates the ability of ILs to separate and recover cellulose and lignin from a mixed system.

Cebrian Gomez MG, Grimes SM, Moore D, 2008, In-Vessel Composting Of Food Waste –A Catering Waste Management Solution, Communications in Waste and Resource Management, Vol: 9, Pages: 19-23, ISSN: 1754-5714
An economically viable system for converting catering food waste into a high quality compost has been developed. The scientific and technical requirements for composting, with food waste as the main feedstock, and fully compliant with EU regulations, to give a marketable product is described. Chemical and physical analyses of catering food waste show that it does not have the correct composition or consistent particle size for direct use as a composting feedstock. For food waste specifically there is alsoa requirement to achieve high temperatures in the composting process for long enough to destroy any pathogens present. The conversion of food waste to a high grade compost has been achieved in this work by a combination of macerating and dewatering to homogenize the feedstock and reduce the water content, with the addition of a carbon-rich bulking agent to achieve the correct C:N ratio and absorbany excess of water in a closed in-vessel composter. The composting process in a catering establishment trial was completed after 34 weeks without external heating giving a product that had been treated at sufficiently high temperatures to ensure pathogenic depletion to give a high quality product measured against BSI PAS 100 standards.
