Here's a green tip
for holiday weekend picnics and gatherings: instead of paper or foam disposable tableware, consider using plates made from biodegradeable materials: bamboo or bagasse
(sugar cane fiber).
Bambu makes their sturdy plates and dining utensils from veneer of sustainably grown bamboo. These disposables are free of dyes and bleaches and are both more expensive and much nicer looking than their paper counterparts. You may be tempted to wash and re-use, but they are indeed designed for single use.
Bagasse doesn't have the same great looks, but plates made from this stuff are cheaper and microwaveable.Bambu Veneerware: A set of 8 plates ranges from $6-$14, depending on size, at SF's Branch. Utensils are also available, though often out of stock.
(The Bambu line is also available at Cole Hardware's four stores.)
Bagasse Tableware These come in packs of 25 and range from $4 - $5.50/pack, depending on size, at Branch. Utensils, cups, and serving pieces are also available.
