Eriska Hotel Jora JK5100 automated composter supplied by Joraform Introduction The Eriska Hotel is a luxurious 25 bedroom 5 Star hotel located on a 300 acre site in rural Scotland. The complex includes a golf course. The business made a commitment to working in a sustainable way – to improve environmental performance, minimise waste, reduce resource use and to raise awareness and adopt sustainable business practices. Nature and quantity of waste treated on site The amount of food waste produced by the hotel is around 10-15kg per day and roughly 100kg per week The hotel now composts around 80% of its food waste Wood pellets are fed into the mix to maintain balance – the ratio is about 1 part wood pellets to 10 parts food waste. “We no longer buy compost and it has helped raise the quality of our soil” Beppo Buchanan-Smith, Co-owner of Eriska Enterprises Jora JK5100 in housing Key features Size: 295x117cmx150cm Spatial requirements: Requires its own building Weight: 850Kg Capacity: up to 5kg of catering waste per day Energy: requires electricity supply Housing: shed/covered area with a flue pipe Maintenance: annual service Output: compost can be used directly on the hotel's golf course and flower beds
How the on-site treatment system is managed The system is fully automated, requiring little operator time by ground staff. This amounts to 1 hour a week to empty and reset the chamber Food waste is emptied into a shoot with a grinder which chops the waste into smaller pieces The whole process takes around 4 weeks from the food first entering the composter to it coming out as compost. Compost is often mixed with soil to produce a mulch Maturation isn’t normally required; dependant on how wet the mix is it can normally go straight on the gardens and mulched with the soil to improve both. If the mixture is starting to smell or become too wet this can be adjusted by adding wood pellets Both sawdust and wood pellets come from the onsite biomass heating system The Jura machine has several in-built safety functions. The chute is locked during grinding. When the chute is open, the grinder motor is locked Lessons Learnt Avoid putting large amounts of citrus fruit peel into the composter as it makes the finished product too acidic Eriska Hotel Costs Capital costs were in the region of £19,000 for the unit, with no other costs incurred Operating costs - requires to be housed in a shed or covered area with an electricity supply Waste management savings - by composting their food waste on site they have reduced bin collections costs by 50%. This equates to a £2000 annual saving With the reduction of their waste uplifts the hotel projects that the composter will have paid for itself in less than ten years The hotel no longer buys compost as the compost produced is of good enough quality to use of the golf course and flower beds. How food is separated for treatment The composter is located a short distance from the kitchen The kitchen staff have a routine of collecting food preparation waste in one bucket and plate waste in another Once a waste bucket is full someone from the kitchen will take it to the shed to be emptied into the composter Use of outputs from treatment The hotel has found that the composted material is of a fine enough quality to be used directly on the hotel’s golf course greens and flower beds The output is also mixed with soil and used for replacing divots on the golf course.
