Grassroots Project for Environmental Protection in Ha Long Bay Area, Vietnam (2009-2012)

Activity 1: Survey on generation of wastes and wastewater from floating village and tourist boats with participation of village residents and tourist boat companies

a. Floating villages
(i) Wastes
Measurement of wastes generated in a floating village (Vong Ving Floating Village) was carried out for 10 days in November 2009, January 2010, April 2010 and July 2010 by several waste categories. In addition, interview to residents were carried out about collection, disposal and recycling of wastes at Vong Vieng Village and Cua Van Village. Major findings are:
- Coal briquette are widely used for cooking and heating in floating villages, therefore, coal briquette ash occupies a large portion of waste generation.
- Some recyclable wastes, such as bottles, cans, PET bottles, have been collected separately and transported to land.
- Other wastes are collected once two days or a week. Since organic waste are easily rotten and smell, some residents throw away organic wastes into the sea. However, in Vong Vong Floating Village, the residents are utilizing food wastes as foods for their fish farming.

(ii) Wastewater
As for wastewater generation, interview and observation of dishwashing and clothes washing were carried out at Vong Vieng Village and Cua Van Village. From the observations, it was found that the residents tend to use too much detergent for dishwashing and clothes washing, therefore, reduction of the use of detergent can be effective for reduction of pollution load of wastewater and become an economic incentive for residents.

b. Tourist boats
Measurement of wastes generated targeting 8 tourist boats was carried out for 10 days in November 2009, January 2010, April 2010 and July 2010 by several waste categories. In addition, interview to managers of tourist boat companies were carried out about collection, disposal and recycling of wastes. Major findings are:
- Organic waste occupies a large portion of waste generation from tourist boats.
- One tourist boat company has adopted pre-cooking food materials on land before boarding, in order to reduce waste and wastewater generation on tourist boats on sea. This method is simple and applicable to other tourist boat company.
