Following to the implementation of Arcola Waste Management Strategy, a detailed resource monitoring was carried out, for the period from September 2006 to October 2007, to observe materials intake and energy consumed annually, so as to produce efficient waste reduction schemes.
The monitored areas included: electricity, gas, water, glass, paper and plastics. It was conducted by tracking bills and invoices on the aforementioned areas during that specific period of time, on how much Arcola has consumed and spent.
After consolidating all the raw data collected, a detailed analysis is made as follows:
Among the three areas of waste, paper, glass and plastics, the amount of paper waste produced in Arcola accounted to 72% of the whole sum, which weighed close to 14150kg, while glass and plastics taking up 27% and merely 1% of the sum respectively (as shown in Chart_General). Meanwhile, glass and paper consumption took up to 41.7% and 43.6% of the total expenditure on the monitored areas.
Brochures were the main culprit for the paper waste, which took up to 57% of the sum, followed by printing materials (posters by 15% and flyers by 11%), sanitary waste (napkins, paper towels and toilet rolls by 7%), office A4 paper and plain tickets surprisingly amounted to 4% and 3% as well (as shown in Chart_Paper).
As for glass, it showed an average disposal of 347.52 kg per month. The relatively steep slope for August to September 2007 on the chart for glass consumption suggested a larger amount of glass waste were produced over the summer from our foyer café due to alcohol consumption (as shown in Chart_Glass).
For electricity consumption, it summed up to the level between 2000 to 3000 kw/h from our two meters each month and there is a reasonably larger amount of electricity consumed from November to January due to less daylights. It is noted that there is a 24% increase in electricity charge from June 2007 onwards. Whereas for gas consumption, it varied significantly from December to March and reached up to 9000 units in March, that was possibly due to misread of our three meters or incorrect estimation, which exact reasons cannot be retrieved by now (refer to Chart_Gas&Electricity).
Generating from the findings, recommendations are listed below:
First, there was a huge difficulty to retrieve exact and correct data on electricity, gas, water consumption and waste disposal, since no system was set before to keep track on the bills and no regular check-up of meters were done, which rest it hard to investigate suspicious or missing data and generate a full report. Especially for Arcola’s water consumption, meters were never read before, either by Arcola or the service provider. Arcola has been charged all the time by just an annual lump sum and make it impossible to retrieve data needed on water consumption. It is strongly recommended that meters should be read at least on a weekly basis and bills should be read thoroughly and monitored all the time if energy reduction plans are to be carried out.
Second, paper is the major waste among all in Arcola and seasonal brochures account to over half of the annual paper waste. Given that Arcola has been encouraging e-Newsletter for some time, it would be viable if Arcola actually starts an e-Newsletter campaign and actively cut down its paper consumption on seasonal brochures. Before actually making the drastic change to publishing e-Newsletter, considering the possibility that some of the customers prefer not to use email or give out email address, seasonal brochures which are printed on recycle or thinner paper would be an alternative.
Third, another note for paper waste is on plain tickets. It is surprising that paper waste on tickets amounted to 3% of the sum and 2% of the annual expenditure. This can be drastically reduced if e-ticket or m-ticket (mobile ticket) could be used to substitute paper tickets in the long run. But it is noted that the difficulty to monitor the auditorium and the huge cost incurred to set up the system may be a drag to adopt this alternative for now.
Fourth, plastics are not currently recycled in Hackney and all of the plastics waste went straight to the bin. One possibility is to use degradable plastic bottles in the café and refrain from consuming plastic forks, knives, spoons, plates, etc.
Fifth, the 205kg of paper towels thrown in the bin can be reduced by installing hand dryers and offering clean towels in bathroom for customers.
