Indonesia has a wealth of natural resources is high, including mineral resources into pavement materials. Utilization of natural resources such as raw materials pavement still has not been developed, especially to overcome the problems related to premature pavement damage. Asphalt Pen. 60/70 and natural zeolite is a natural asset that can be used, but the study linked the two materials are still not widely practiced.Merging the two materials in the testing done with the design of the test specimen using 5 filler content variation, the variation of 1 (100% stone dust: 0% natural zeolite), variation 2 (75% stone dust: 25% natural zeolite), variation 3 (50% stone dust: 50% natural zeolite), variations 4 (25% stone dust: 75% natural zeolite) and variation 5 (0% stone dust: 100% natural zeolite). Then from the value obtained KAO Marshaal testing to obtain VITM value. And the results obtained that the higher bitumen content, then the value of VITM will decrease. This means that the higher the bitumen content, the cavity in the mix will be reduced. This happens because the addition of asphalt to make the air cavity that there is increasingly reduced because filled by asphalt.

Legislative Framework

Abstract In 1996, Georgian mining and extractive industry moved to a new stage as a result of the adoption of a new law on subsoil, which prepared grounds for the development of a legislative framework regarding the use of country’s subsoil and created new economic settings for the industry. Mining and extractive industry play a significant role in Georgia’s sustainable economic development. From 1999 through 2020, the output value of the industry (excluding non-renewable energy resources: coal, natural gas and oil products)is estimated at of 5,6 billion Lari (GEL). The majority of deposits of mineral resources in Georgia are mainly small and medium in size. Considering the current rate of their exploitation, within 15-20 years their majority will be exhausted. Over time, the country’s economy will face a serious problem as it will need to import raw materials. It is therefore important to look for feasible technologies for the application of unconventional raw materials, namely secondary raw materials that come with essential mineral resources. This will allow to maintain the potential of mineral resources of the country. The work presents the outcomes of the Mining Institute’s current studies on qualitative, quantitative and assimilative technologies and possibilities of the application of mining waste as secondary natural resources. Research methodology is based on the principles of Green Economy that implies linking mining and extractive industry to circular economy, aiming at rational assimilation of natural resources by applying the 3R (reduce, reuse and recycle) approach. Within the frames of the study, technologies were developed for obtaining construction, glass and porcelain raw materials (from spoiled rock layers stored and extracted from operating open pit mines of the Chiatura manganese and Bolnisi ore deposits/queries), along with those for manufacturing products with such materials.

Abstract Growing awareness of limits set by exhaustibility of natural resources has led to a conclusion that only through their valuation in monetary terms one may assess a comprehensive economic impact of their use. Thus mineral resources have been included from the beginning to almost all studies regarding natural resources assessments. The first result, widely recognized by international community, of researches came in the 1993 – edition of the “Handbook of National Accounting: Integrated Environmental and Economic Accounting”. One of the key outcomes of these works was a conclusion that measuring value of mineral resources for mineral raw materials production, alongside with physical flows of these materials, environment related transactions and measuring impact of the economy on the environment, should make basic pillars of this newly designed system, later named as the System of Integrated Environmental and Economic Accounts (SEEA). As implementation of SEEA is still in a primary stage, many methodological issues remain unsolved. This article attempts to enumerate achievements made so far and indicate issues in need for further development. Taking into account the importance of mineral resources for further economic development of Poland authors indicate a necessity to develop and implement methodologies for monetary assessment of resources/reserves available, extracted and depleted in order to form a methodological base for a meaningful policy of sustainable growth. The special challenge results from monetary assessment of explored but yet undeveloped mineral deposits.

The Republic

The mineral resources of the Republic of Srpska enable the exploitation and processing of mineral raw materials in the metal, metal processing, construction, chemical industry, cement industry, ceramics and construction materials, etc. The largest part (over 90% in terms of value) are reproductive materials for processing in other industries and a smaller part are products that go directly to the market. In the conditions of increasing and faster technological development and with the tendency of increasing exploitation of natural resources in the world with changes of previous life conceptions, there was a need to analyze the sustainability of the mineral resources and natural resources use for further development of the Republic. The importance of a clearly defined Strategy for Management and Utilization of Mineral Resources and Raw Materials in the Globalization and Advanced Technologies Era is shown in the paper, which would enable planning and defining the goals of the use of mineral resources, clearer identification of the potential mineral resources, and basic starting data for creating the activities in order to more rational and economically efficient management of the natural resources in the Republic of Srpska. At the global level, it has become clear that geology is a very important geopolitical factor in the 21st century. Тhe importance of disposition аnd knowing where, how many and what types of mineral resources we have, can be achieved through to the several strategic activities. The development of the Strategy for the Management and Utilization of Mineral Resources of the Republic of Srpska, the "central interactive" database of mineral resources and the establishment of the Agency or the Directorate for Mineral Resources, are some of the proposals for these strategic activities.

The twenty-first century is being touted as the Asian century. With its stable economy, good governance, education system, and above all the abundant natural resources, will Australia to take its place in the global economy by becoming more entrepreneurial and accelerating its rate of growth, or will it get infected with the so-called Dutch disease? It has been successful in managing trade ties with fast-developing economies like China and India as well as developed countries like the United States. It has participated in the growth of China by providing iron ore and coal. Because it is a low-risk country, it has enabled inflow of large foreign capital investments. A lot will depend on its capability and willingness to invest the capital available in entrepreneurial ventures, its ability to capture the full value chain of natural resources, and to export the finished products instead of raw materials, while building a robust manufacturing sector.

Key Resources

Natural resources play a significant role in the development of the global economy. This refers, in particular, to strategic fuel and mineral resources. Due to the limited supply of natural resources and the lack of substitutes for most of the key resources in the world, the competition for the access to strategic resources is a feature of the global economy. It would seem that the countries which are rich in resources, because of this huge demand, enjoy spectacular economic prosperity. However, the results of empirical studies have demonstrated what is known as the ‘resource curse’. This article concentrates on the characteristics of the paradox of plenty, and in particular on the possibilities of preventing this phenomenon. The aim of this article is to identify the measures of economic policy with which to counteract the resource curse, based on the relationship between the state and the extraction business. Upon the critical analysis of the relevant literature, we concluded that the state’s economic policy, implemented in cooperation with the extraction business, is increasingly important for the prevention of the resource curse. In the context of the resource curse, the optimal and most consensual instrument, in comparison with other resource sharing agreements, is a production sharing agreement (PSA), which should also be adjusted to the current local economic conditions in a given country.
