TIM EVANS ENVIRONMENT is independent. It is not linked to any particular technology and although it does work for technology providers it is independent of them. Its objective is to give impartial, confidential advice to clients in order that they are able to achieve sustainable, cost-effective solutions that use the technology that is most appropriate for their particular situation.

This is based on many years’ experience of actually working with and managing a wide range of technologies for wastewater treatment, biosolids and residuals treatment, recycling, farming and other land uses.

A key principle is that solutions must comply with current (and reasonably anticipated future) legal requirements, and that this compliance should be demonstrable. On top of this the concerns and perceptions of stakeholders should be recognised. If recycling is involved there should be a market for the material being produced, and there should be due diligence and an awareness of emerging issues.

Work to date has included:-

• Designing and managing sustainable biosolids recycling that was fully traceable and compliant with all legal requirements and met all time and financial targets.
• Internal benchmarking to identify opportunities for quality, efficiency and cost improvements.
• Field trials into the effects of biosolids and composts on the yields and quality of crops, soil metals, earthworm populations and effects on soil microorganisms.
• Risk evaluation and development of good practice protocols for the use of wastewater biosolids and other organic residuals as soil improvers based on the principles of Hazard Analysis and Critical Control Point (HACCP) so as to enable strict-liability latent-defect insurance, including gradual pollution, for a period of 25 years.
• Conducting HACCP analyses for biosolids and waste processes from prevention of pollution by control at sources, through treatment to the planning and application of biofertilisers to land. Designing internal control questionnaires and training their personnel so that they are enabled to conduct internal audits and gap analyses and to roll out HACCP across their companies.
• Advising technology providers on opportunities for new treatment technologies for organic residuals, benchmarking them against their potential competitors, SWOT analyses and in particular the likely impact of emerging legislation.
• Standards for composted materials
• A scoping study for a stakeholder partnership for using organic resources on land, this involved stakeholder meetings, drafting a business plan and a residential workshop.
• Re-evaluating a biosolids strategy to provide a sustainable solution that was affordable and practicable in the context of local geography, climate and farming and that uses appropriate technology.
• Contributing to a multidisciplinary team advising on a politically acceptable solution for first time sewerage scheme in an arid region with high quality tourism, that made the best use of all available resources for financing the lifetime of the scheme.
• Designing safe compliant composting systems.
• Advising on emerging legislation.
• Strategic and organisational studies for new biosolids and residuals facilities.
• Design and costing a food waste recycling facility producing biofertiliser and biogas by anaerobic digestion
• Formulating peat-free products for gardeners based on composted materials. Designing the packaging, market research, launching these fast moving consumer goods onto the wholesale market and managing production, sales and distribution.
• Designing land drainage to intercept up-slope seepage and under-drainage to remove surface water
• Advice on phosphate recovery and ammonia treatment from process liquids.
• Environmental impact study of the contribution food waste disposers can make to household waste management
• Advice on residuals management for a wastewater treatment plant dedicated to a large petrochemical and industrial complex and preparation of a code of practice.
• Developed the Airbeam Roller Stockpile Cover (patented) the practicable solution to safe containment of stockpiles

Projects to date have been in Brazil, Cyprus, Egypt, England, Ireland, Nigeria, Slovakia, Scotland and USA.
