The aim of this paper is to identify patterns of waste management in the Bali archipelago tourism area. The Nusa Penida District is a new tourism destination located in the Southeast of Bali. In 2018, there were average 391,071 tourists/day coming and 45,520 local residents live in this area. The total amount of waste produced in Nusa Penida District is 15.90 tonnes/day or 173.61 m3/day. High tourist activities have not been handled by a good waste management. Questionnaires were distributed randomly to the public and tourists to find out the pattern of waste management. Observation also conducted to build the material flow analysis as a waste information baseline. Around 48.21% organic waste used as livestock feed and 8.45% dumped carelessly to the environment. Around 32.51% anorganic waste be burnt and 45.68% waste dumped carelessly. Moreover, Nusa Penida District facing offering waste management problem caused by their cultural activities. In total, around 8.82 tonnes/day waste is dumped in landfills and total unmanaged waste around 6.73 tonnes/day.

Abstract In Kenya, agriculture is an important economic activity, which implies that a significant amount of bio-waste is generated. This is on one hand a waste management problem, but on the other hand, it is an opportunity for creating a sustainable bioeconomy. Therefore, this study investigates the potential recovery of bioresources from Kenyan bio-waste. The study first quantifies occurrence, current usage and disposal of three selected biomass types, being banana, potato and coconut waste. Next, material flow analysis (MFA) is used to systematically track the mass flow of these wastes. Finally, the potential of biomolecules, biomaterials and bioenergy from the waste streams is evaluated. The study revealed that 6007, 426 and 49.5 kt of banana, potato and coconut biomass is wasted. All these wastes can be biorefined, offering potential towards recovery of; flavonoids (88.3 kt), starch (377 kt), cellulose (2000.7 kt) and biogas (1757.0 GWh), being the total potential of the main bioresources from the three waste streams. The study therefore, concluded that, with proper waste collection, sorting and valorisation, there is a huge potential for bioeconomy in Kenya, at the same time reducing waste management problems.

Starting Point

Waste of electrical and electronic equipment (e-waste) is the outcome of the technological progress in electronic industry determining the exponential growth in amount and variety of the electrical and electronic products (EEE), the growth of economical welfare and unsustainable consumption. E-waste management systems (MS), implemented in the EU countries are not able to cope with the e-waste problem properly, especially in the new EU member countries. The best case scenarios of e-waste MSs from advanced countries could not be transposed directly to the countries behind the requirements of efficiency. The analysis of particular e-waste MS is essential for evaluation of its complexity and peculiarity. The aim of this paper is to represent the research of agent based material flow analysis (MFA) in the e-waste MS, as the measure to reveal the potential points for improvement. MFA was performed as a flow of goods (EEE). The case study of MFA employment for the Lithuanian e-waste MS represents the following benefit: 1) estimation of the real EEE flows, including amounts of e-waste generated; 2)detection of the roots of inefficiency; 3) starting point to perform structural selection of relevant impact factors determining the current operation of the system. The study demonstrates that agent based EEE flow analysis incorporating life cycle thinking approach for the national e-waste MS gives a broader view to the system than the administrative system used to cover. Therefore employment of EEE flow analysis is useful for improvement of the e-waste MS.

Organic Waste Management

Kegiatan komposting sampah kota umumnya tidak berjalan sinambung karena kegagalan pasar, lemahnya dukungan pemerintah, lemahnya manajemen dan ketidaklayakan teknik yang digunakan. Penelitian ini bertujuan menyusun  konsep metabolisme pengelolaan sampah organik melalui teknologi komposting di wilayah internal perkotaan. Metodologi penelitian ini dilakukan dengan metode kuntitatif dan eksploratif deskriptif melalui analisis matematis, analisis multikriteria pengambilan keputusan, analisis aliran material, dan analisis finansial. Penelitian menyimpulkan bahwa metabolisme pengelolaan sampah organik melalui teknologi komposting di wilayah internal perkotaan adalah metabolism sistem fisik, sosial, dan ekonomi dari kegiatan pengelolaan sampah organik yang bercirikan metabolisme antropogenik untuk keberlanjutan kota sedang. Kata kunci: Pengelolaan sampah organik, metabolisme, aliran material, komposting, analisis multikriteria. AbstractComposting of municipal solid waste activities generally do not run continuously because of market failure, lack of government support, poor management and inability of the techniques used. This study aims to develop the concept of the metabolism of organic waste management through composting technology in internal urban areas. Theresearch methodology was conducted by the method of quantitative and descriptive explorative through mathematical analysis, multicriteria decision analysis, material flow analysis, and financial analysis. The study concluded that the metabolism of organic waste management through composting technology in internal urban areas is themetabolism system of physical, social, economic and environmental of organic waste management activities characterized by anthropogenic metabolism to the sustainability of medium cities. Key words: Organic waste management, metabolism, material flow, composting, analysis of multicriteria
