Waste Handling

In a sustainable society based on an eco-cycling philosophy it is important to establish efficient waste recycling, as well as systems for re-use. Such systems include both material recovery and the extraction of bio-energy and nutrients using natural ecological techniques. In order to save energy and reduce transportation, which accounts for more than 60 % of the waste handling costs, it is essential to develop small-scale and local systems for the recovery of nutrients from waste products. The organic waste is an important resource of nutrients and should therefore be recycled and put back into the eco-cycling system. Every year in Sweden approximately 2,5 million tons of organic waste is not recycled, but instead incinerated or landfilled (Naturvardsverket, 1996). From an eco-cycling point of view the organic waste should not be landfilled as most of the environmental problems during the lifetime of a landfill is shown to be connected to the organic waste. Landfill gaz, leachate, odours and hygienic problems are all a result from landfilled organic waste, which instead ought to be composed or digested (Naturvardsverket, 1996). Investigations have shown that over 75 % of mixed solid household waste is biologically degradable and that nearly 50 % can be composted and re-used as a nutritious top-soil additive. Therefore, a recent Directive from the European Community prescribes that at least 75 % of the household waste in Europe shall be recycled and re-used by year 2005.

Waste is a problem that must be faced by residential communities both in urban and rural settlements, so it needs to be systematically structured and sustainable. Conventional waste handling that has been implemented by the community cannot produce an appropriate solution, this is evident that there is still a large volume of waste that has not been managed properly. The purpose of implementing community service activities in the village of Sedapurklagen in Benjeng Gresik is to utilize household waste through compoter and biopori as well as the application of Biopori to treat household waste that can also reduce waterlogging during rain. The implementation method is used so that the purpose of this service activity is to empower the community about managing household waste to be composted through composter, as well as training on composting from composter and biopori. The target of this activity is the mothers of family welfare coaching (PKK) in the village of Sedapurklagen, Benjeng Gresik. The result of this service is that the community has begun to process organic waste to make compost and million biopori pipes around the Posapur, Sedapurklagen Gresik to reduce the presence of standing water during the rainy season.

A lot of waste from agriculture, industry, household and food waste is accumulated every year in Lithuania. Waste is polluting environment very intensively. From sanitarian point of view there can appear dangerous sources for people and other biological objects. The main method for utilisation of waste still remains landfilling. So as a huge problem appears operation of landfills, cumulation of leachate and biogas. The last years Vilnius city municipality directly changed the waste managing strategy. As it was estimated, food waste forms about 46,6 -56,6 % from total household waste amount. It was decided to turn this source from landfill to composting facilities, organise separate food waste collection from companies and habitants. The system was iniciated in 1997, but it develops very slowly. A private company "Chitinas" has started its work independently in neighbouring Vilnius city district. Two main unordinal methods were used for destruction of organic waste, both very usual in nature, but still rarely used in practice by farmers. Such methods are called in Lithuania "nontraditional farming". We estimate these methods as modem and perspective for organic waste destruction in big cities. With their help we can get ecologically safe, good natural fertilizers, without seeds and infections, having less nitrates and fosphates. Besides, we get an alternative product - material called "chitin", which could be chemically purified and has a perfect future in chemistry and medicine.

Urban Waste Management

Organic waste management is a growing issue due to the unsustainable practices of its disposal. Sewage treatment plants are designed to treat wastewater to produce a safe effluent. However, one of the by-products, the sewage sludge which is disposed off in landfill or used as fertilizer in agricultural operation is high in pathogens. Sustainability can be achieved by Vermicomposting of organic matter which involves accelerated cycling of nutrients though a closed cycle whereby waste products are put to productive end use. Vermicomposting and vermifiltration are natural waste management processes relying on the use of worms to convert organic wastes to stable soil enriching compounds. Domestic wastewater management can be accommodated through these processes in a sustainable manner. A considerable reduction in pathogens has been noticed in the end product to a level that it can be safely applied to land. This paper provides an overview of the system characteristics of management systems utilising vermiculture, to manage wastewater. The process can be used in a small scale for household waste treatment to rural or urban waste management.

Law No. 18 of 2008 on Waste Management prioritizes waste handling nearer the generator by considering economical value remained. In Depok City, waste handling at the community level has been performed at the Waste Treatment Unit (WTU) and waste bank. WTU focuses on organic waste treatment, while waste bank for inorganic waste recycling. The paper aims to identify waste generation and to evaluate the operational activity of the facilities. The sampling procedure proceeded for 8 days consecutively for 14 WTUs and 1 day for 7 waste banks applying stratified random sampling from a total of 30 WTUs and 428 waste banks operated in Depok City. Waste received daily were varied between 95,32-1.436,98 kg of organic waste at each WTU and 69,65-868,40 kg of inorganic waste at each waste bank. The variation of waste received was proportional to the number of inhabitants served and the character of the community surrounding the facility. The performance of the facilities could be improved including through promotion and financial support attained from the retribution. Waste handling at the community level could reduce the amount of waste transported to the Final Disposal Site (FDS) and reduce land required for FDS which becomes difficult to find especially in big cities in Indonesia.

Recycle Plastic

The use of plastics has increased over the past two to three decades especially in the areas of medicine, engineering and domestic application. Consequently, it consumption has generated increase in industrial and domestic waste. Since most plastics are not biodegradable they tend to have adverse short and long term effects on the environment, living organisms and the economy and the situation is not different in Ghana. Although some efforts are being made to reclaim the waste, it is very prudent that recycling of the collected waste is included in this scheme. This paper seeks to outline the design of a machine to recycle plastic waste. This will help keep the environment clean, safe, save energy and will also leads to resource recovery and the creation of jobs for the unemployed.

Biogas Reactor

In Sweden the utilization of household waste for energy purposes is quite significant already today. Individuals sort the household waste in different fractions where the organic biologically degradable material is separated into one fraction, while other type of combustible materials into one or more fractions. The rest of the waste is normally going to recycling, like metal, glass and paper. Concerning industrial waste we have a similar situation. In Vastmanland and eastern Uppland a collection system with sorting of waste into many fractions has been in operations for 15 years. This has led to a situation, where most waste is sorted in a very good way. Just 1-2 % of the waste is put into the wrong container. At the central waste recycling plant at Gryta in Vasteras, the biologically degradable organic waste is mixed with fat sludge from restaurants and lay crops like clover and grass into a large biogas reactor. This now has been in operations for four years. It has been proven that the residue from the reactor is not causing any problems with heavy metals or organic toxics when used as fertilizer, and the residue is actually even CERALIA and KRAV certified. When it comes to extension of biogas production, we are running into a shortage of feed stocks generally in most cities in Sweden. It therefore becomes more interesting to utilize more agricultural wastes like straw, but also to introduce high temperature gasification for e.g. methane production. Today most recycled wood and similar is combusted. This gives heat, but unfortunately no organic materials to the farmlands. We also see a trend towards low energy buildings reducing the need for heat, while the wish to replace fossil fuels fortransportations is increasing. In Västmanland and other parts of Sweden high temperature gasification processes with circulated fluidized beds (750-900 oC) as well as CORTUS high temperature processes using steam for the actual gasification at 1100 oC are investigated. These techniques are also discussed in the paper.

In September 2015, the United Nations included ‘sustainable consumption and production’ as part of its 12th goal of sustainable development. The EU announced its Circular Economic Package in December 2015 to move from the existing linear economic structure to the net environmental system. Recycling of household waste has become more significant as a circular economic policy has been implemented to reflow waste into the economy through recycling worldwide. In this study, Korea’s household waste generation for 20 years from 1998 to 2017 was analyzed through statistical techniques. Waste generation tended to increase in the order of plastics and cans, and papers tended to decrease. The amount of bottle wastes has been on the decline after increasing. A questionnaire survey on recycling priority was conducted on 261 people, including participants in the EARTH-2019 recycling experience hall, using the analytic hierarchy process (AHP) technique. According to the survey, the recycling priorities of six types of household waste are (first) plastic, (second) cans, viny, scrap metals, (third) paper, and (fourth) bottles. Statistical analysis of mid- to long-term household waste generation and AHP-based household waste recycling priority survey results can be used as basic data, such as environmental analysis in Korea’s recycling-related policies and research.
