Indonesia has a big problem with solid waste, because there is no proper system to deal with the produced trash. Therefore a lot of trash ends up in the ocean, mangrove areas and in forests. Manengkel Solidaritas had a project to teach coastal communities to adapt to the trash problem and it was a success. Currently they are looking for new funds to transfer the concept to more villages.


  • Solid waste can be found in every area of the coasts of North Sulawesi, it destroys the marine system and kills a lot of animals living in the ocean

  • Many coastal communities are not aware of the long term effects of throwing solid waste in the ocean

  • There is no system to deal with the trash produced in daily life, therefore no one feels responsible for the trash

Waste on a scale



The project is focused on three major themes:


Waste management

  • To improve the sustainability of waste management systems in coastal villages around the bay of Amurang

  • Training to increase community income based on plastic segregation and sales

  • Training sessions that will provide communities with effective recycling tools and techniques, especially for making compost and preparing vertical gardens in Arakan village


Food Security

  • Encourage communities to produce food locally and become less dependent on external supplies

  • Training in VertiCulture and organic farming

Environmental Education

  • Classes to raise awareness of the threats to marine and coastal environments

  • Training for teachers

Training organic farming


Waste Management

  • Successful implementation in the villages of Rap-Rap, Arakan, Sondakan villages, North Sulawesi, Indonesia\

  • Households in three villages were equipped with double containers bins

  • Waste collection centres were established in all three villages

  • A monthly monitoring system of household waste was established

  • Five households of each village took part in a pilot composting system

Food Security

  • Raising awareness of the benefits of traditional and locally grown food

  • Dependency on external food supply was decreased by 20%

  • The number of households practising VertiCulture and organic farming increased by 20%

Environmental Education

  • 70% of students (grade 4 and 5) from the villages attended classes about coastal environmental care.

  • Three teachers from three primary schools were trained to deliver lessons on marine and coastal environment issues ensuring the long term suitability of marine education in these areas

Training in Waste Management

Manengkel Solidaritas organised training sessions that covered two areas: organic and solid waste management. The first one was about simple way of making compost. The second session concentrated on solid waste, in particular on plastic bottles.

The most important issue was how to combine those two waste sources in efficient way. In this regard, concept of the vertical garden using both organic compost and plastic bottles was introduced and practiced. In first session attended 12 participants representing households (out of 20 targeted), in the second one the number increased to 20. People, who were trained received plants seeds and within practical sessions they constructed vertical gardens in front of their houses.
