The Western Mail reports that Welsh entrepreneurs have pioneered a way to turn biodegradable household waste into an “aphrodisiac for plants”, using 32 million “workers”. With the help of millions of worms, the transformation from rubbish to fertiliser takes less than two weeks, and the company has won cash backing from the National Assembly to develop the process.
Pioneered by John Winslow and Malcolm Rich of Brecon-based VitalEarth Group, the scheme not only helps tackle the massive problem of what to do with the rubbish, but produces a natural plant food which makes a dramatic difference to plant growth, appearance and disease resistance, according to experts. The fledgling company, assisted by business support specialists Entrepreneur Action, has won a £175,000 Regional Selective Assistance grant from the Assembly to help establish three sites operated by council rubbish disposal contractors LAS Waste. The sites, at Lampeter, Pembroke Dock and Johnstown, near Carmarthen, will eventually employ 25 people.
They have also lodged planning and licensing applications for several sites in England. Wales produces 1.5 million tonnes of domestic waste a year, much of it biodegradable. Currently, only 7% is recycled, but the mandatory target for the UK is 25% by 2005 – hence the recent speculation that householders may face a “black bin-bag” charge for rubbish collection.
With the support of the Welsh Development Agency, Mr Rich and Mr Winslow spent two years developing a computer controlled “Rapid In-Vessel Composting System”, which accelerates the normal decomposition process from around two months to just seven days [not sure about this claim – KS]. In full-scale production, the waste will then go through a vermistabilisation plant, where around 32 million worms will be introduced.
Tonnes of worm droppings, called casts, which contain hormones that stimulate plant growth, will be collected each day and marketed as “Vitalizer”, which is already proving popular with gardeners. The process has attracted widespread attention, with local authorities facing new waste recycling targets

Egypt reviews Red Sea waste management system – Dailynewsegypt
Egypt’s Minister of Local Development and Environment, Manal Awad, and Red Sea Governor Walid El-Barqi held an extensive meeting to review the performance of the governorate’s waste management system and discuss measures to improve environmental services and operational efficiency. The meeting, held during Awad’s visit to the Red Sea Governorate to mark World Environment Day, focused on assessing current challenges facing waste collection, sorting, recycling and disposal operations, as well as identifying priority actions to strengthen the system’s performance. Awad stressed that the government places significant importance on developing an integrated waste management system in the Red Sea Governorate, given its strategic importance as one of Egypt’s leading tourism destinations. She emphasized the need to comply with environmental and technical standards governing sanitary landfills, waste treatment facilities and environmentally sound disposal practices. During the meeting, officials reviewed the current status of waste management operations in Hurghada, including collection, transportation, sorting, recycling and final disposal activities. Discussions also covered the infrastructure upgrades required to improve system efficiency and ensure the proper operation of sanitary landfill facilities. Yasser Abdullah, head of Egypt’s Waste Management Regulatory Authority, presented updates on temporary waste collection and sorting sites and outlined measures to strengthen operational management and oversight. He highlighted the importance of improving monitoring mechanisms for waste handling activities and maximizing the recovery of recyclable materials while reducing informal and unregulated practices.
