A few cups and plates go a long way. Request caterers to use reusables rather than disposables and ask that leftovers be donated to charities. However, batteries are difficult to recycle and must be disposed of as hazardous waste. So, why not try reusing them. You can now buy rechargeable alkaline batteries for most products.
Many companies ask their customers to return used toner cartridges.
They will provide a UPS shipping label and will pay shipping costs. Contact the manufacturer for more information about their recycling program. The only company in our area providing toner cartridge recharge is CartriCharge West. They can recharge cartridges for several different models of printers as well as some copiers. The company offers free pick-up and delivery service, making it easy to reduce waste while improving print quality and saving money.
