The Impact

One way to improve compost quality of typical organic waste is by addition of additive such as wood chips. This study aims to analyze the impact of the wood chips addition (ratio 1:10) on compost quality of typical organic waste (fruits, vegetables, yard waste, and food waste) in home composter, and to compare the compost quality with the standard of domestic compost according SNI 19-7030-2004. Analysis was conducted on composts raw material, compost maturity process in every 5 days measurement, and on compost product. Analysis of compost product of typical organic waste with addition of wood chips showed that parameters of temperature, moisture content, and pH of vegetables and yard waste has complied the standard whilst parameter of C/N ratio has not complied. The addition of wood chips caused the drop of compost temperature and moisture content, resulted in the decomposition process located in aerobic condition, resulted in production of compost in form of humus in greater volume. The addition of wood chips also caused the compost pH and C/N ratio increased.Keywords: compost quality, home composter, typical organic waste, wood chipsAbstrakSalah satu upaya untuk memperbaiki kualitas kompos sampah organik adalah dengan penambahan bahan aditif, seperti serpihan kayu.

The composition of organic waste reaches 59% of the total municipal solid waste in Indonesia. One way to process organic waste is composting by utilizing microorganisms to break down waste into compost. Naturally, the composting process took a long time but can be accelerated by adding microorganisms to the activator. This study analyzes the quality and quantity of compost using the Biopore Infiltration Hole (BIH) method with activator addition. Composting was duplicated in the yard area with clay soil type and water infiltration rate of 0,3 cm/hour. The BIH was made in a 10 cm diameter, a 100 cm depth, and the distance between the holes was 50 cm. Composting variations consist of variations in the composition of the raw materials and the activators' uses. Variations in the raw material composition consisted of 100% yard waste, 100% food waste, 50% yard waste and 50% food waste, and 70% food waste and 30% yard waste. In contrast, the activator variations consisted of no activator, EM4 activator, and Stardec activator. Compost analysis consists of maturity, quality of physical and macro elements, and quantity of compost. The results showed that all variations of composting had met the standard of maturity and quality of physical and macro elements according to SNI 19-7030-2004. The addition of activator affected composting time and compost quantity. The composting time in BIH with activator ranges from 41-60 days. In BIH without activator ranges from 65-75 days, there was a reduction in composting time by 15-25 days with the activator addition. However, the activator addition caused reducing the compost quantity by 10-20%. The selection of compost variations by scoring results in compost with a composition of 50% yard waste and 50% food waste and the addition of Stardec activators was the best variation in terms of compost maturity, quality, and quantity.

The Impact

In Poland the use of solid biomass obtained from intentional plantations of energy plants is increasing. This biomass is most often processed into solid fuels. There are growing indications that renewable energy sources, in particular biomass production, will continue to develop, so the better we know the raw material, the more effectively we will be able to use it. The results of tests that determine the impact of compaction pressure on selected quality parameters of pellets made from selected biomass types are presented. Material from plants such as Giant miscanthus (Miscanthus × giganteus Greef et Deu), Cup plant (Silphium perfoliatum L.), Virginia mallow (Sida hermaphrodita (L.) Rusby) was studied. The compaction process was carried out using the SIRIO P400 hydraulic press with a closed chamber with a diameter of 12 mm. Samples were made in four pressures: 131; 196; 262; 327 MPa and three moisture levels: 8%, 11%, 14%. It was found that with increasing compaction pressure and moisture content up to a certain point, the density and durability of the pellets also increased. Each of the materials is characterized by a specific course of changes in the parameters tested.

Tilapia can be commercialised to produce sausages. However, the use of minced tilapia or tilapia surimi as the raw material and different mixing durations of the ingredients using the bowl cutter during the sausage production could affect the quality of the products. This study determined the effects of different mixing durations (10, 15 or 20 min) on the physicochemical, microstructural and sensorial properties of sausages made from minced tilapia and tilapia surimi. The washing of the minced tilapia during the surimi production significantly increased the tilapia surimi moisture content and pH, while reducing the protein, fat and ash contents. Subsequently, the addition of other ingredients to produce the sausages influenced the moisture, fat, ash and carbohydrate contents of both types of sausages. The type of raw material and mixing duration showed significant interactions in terms of linear expansion, water holding capacity and colour properties of the sausages. Individually, the tilapia surimi sausage had a better linear expansion, cohesiveness, colour and sensory acceptability than the minced tilapia sausage. The mixing times of 15 and 20 min produced better results for the physicochemical and sensory properties of both types of sausages. However, the gel strengths of both types of sausages were better when mixed for 15 min and the microstructure images supported this. Based on the results obtained, this study concluded that tilapia surimi as the raw material with 15 min of mixing duration is recommended to produce a better-quality sausage.

The Impact

Abstract The formation and storage of man-made waste of water-soluble ores creates a global environmental problem that entails changing landscapes in mining areas and environmental degradation. The involvement of man-made waste in a closed cycle of the production and technological chain makes it possible to reduce the impact of mining and processing on the environment. The use of non-waste (low-waste) technologies, in addition to reducing the environmental burden, allows you to expand the raw material base of the enterprise by replacing the traditional components of the backfill mixture with man-made waste from mining and processing enterprises. The possibility of replacing the traditional, specially extracted aggregate in the backfill mixture with industrial waste of water-soluble ores is experimentally proved. The possibility of creating a cementless backfill mixture is proved. The possibility of replacing the cement binder with magnesium-containing slags of the Chusovsky Metallurgical Plant was confirmed. It was found that the separate activation treatment of the components of the backfill mixture has a positive effect on its rheological properties and increases the strength of the joint mass. The use of lignosulfonate improves the quality of the mixture and the resulting mass. The development of a backfill composite from man-made waste makes it possible to implement the principle of organizing mining production, which provides for the use of intermediate products in cyclic production and excludes the formation of man-made waste of water-soluble ores.
